Aminex PLC: The Ntorya Milestone That Changes the Narrative

From promise to pipeline — Ntorya moves decisively into execution

If you’ve been patient with Aminex (LSE: AEX), you’ve earned every ounce of satisfaction that comes with watching a project transition from promise to progress. The company’s latest RNS — paired with a noticeable uplift in the share price in the days since — isn’t just another update. It’s a confirmation that the long-anticipated Ntorya gas development is no longer theoretical; it’s happening.

Why This Matters

This isn’t corporate spin — it’s logistics. The announced manufacturing of the pipeline and the expected delivery timeline are landmarks in the Ntorya project schedule. Aminex and its partners have moved from feasibility and planning into tangible execution. For energy explorers, that’s when the story changes from “maybe” to “most likely.” And the market feels it.

Price Action Says “People Notice”

Look at the share price: in recent sessions, AEX has climbed significantly from levels not long ago near this year’s lows. On 23 December 2025, the stock was trading substantially higher than mid-December, reflecting tangible buying interest and a growing investor confidence.

That kind of move doesn’t happen on thin air — it happens when speculation meets substance. The share price is flirting with higher territory, suggesting that traders and holders alike are finally pricing in the real prospects of first gas and a concrete production pathway.

Operational Reality — Not Hope

Let’s be straight: upstream energy projects are marathon efforts. Decades of discovery, appraisal, drilling, pipeline agreements, and regulatory engagement go into getting from “we think there’s gas” to “gas is flowing.” What we’re seeing now with Aminex — pipeline build plans, supply chain activity, contractual progress — is the hard infrastructure phase that precedes revenue. That’s enormous. 

Long-term holders have known for years that Ntorya wasn’t a fairy tale. This latest update isn’t just another line in a quarterly release — it’s the proof of life for the project’s timetable. With manufacturing underway and delivery expectations now in sight, the narrative shifts toward the one everyone’s been waiting for: Ntorya delivering gas to market.

What This Means for Holders

For the steadfast investor who stuck through the dry spells, this is validation. It’s that moment when operational progress — not just optimism — begins to show up on your screens:

• Price catching bids again

• Supply chain activity confirmed

• Project milestones being cleared

That’s not speculative chatter. That’s the engine turning.

Final Thought

The doubters can debate charts and moving averages all they want — but in the energy game, the score isn’t kept purely by technicals. It’s kept in pipeline spools being fabricated, contracts being signed, and gas flowing into infrastructure. Aminex is now visibly crossing that threshold, and the market is finally starting to price it in.

If you’ve held this name long enough to remember when this was just a “potential,” enjoy the moment. This is what progress looks like

Momentum Builds: Aminex Focused on Delivery

Ntorya pipeline moves ahead as East Africa’s largest onshore gas project takes shape

Aminex has taken to social media to underline just how far things have come in the last six months — and just how close we are to seeing first gas. The company’s latest update highlights the transition from preparation to delivery, with Ntorya now firmly in construction.

Construction Under Way

The award of the Ntorya-Madimba pipeline contract is the pivotal milestone. Procurement has already begun, groundworks are scheduled for early 2026, and commissioning is targeted for mid-year. This isn’t planning on paper — it’s execution on the ground.

As Aminex noted:

“The Ntorya Gas Development has now advanced definitively into its construction phase… This milestone has in turn catalysed wider activity on the ground and across the project.”

An Expanded Vision

In parallel, operator APT has submitted a revised Field Development Plan. This is no small tweak. It lays out:

• A 35-year production horizon

• A phased development approach

• A materially higher long-term gas plateau than previously envisaged

The scale is transformative. Ntorya has the potential to deliver more gas than Tanzania currently produces as a nation, underpinning power generation, industry, and economic growth for decades to come.

From Restructure to Revenue

The past few years were about restructuring and positioning. That stage is now complete. Aminex is entering the second half of 2025 with:

• A clear pipeline construction schedule

• Strong operator and government support

• A free carry through development to material revenues

The focus is now squarely on delivery and value growth.

Ntorya: A Central Role in Tanzania’s Future

As Aminex put it:

“As the largest onshore gas development in East Africa, supported by a stable regulatory environment, expanding domestic demand, and long-term licence tenure, Ntorya positions Aminex to play a central role in Tanzania’s energy future.”

That’s the big picture. Aminex isn’t simply progressing a gas project — it is part of a national transformation.

Aminex: From Acorn to Oak – Chapter 10: To Be Continued

The road to first gas from Ntorya

---

Every story has a turning point, and for Aminex the next one is close at hand. With the discoveries made, the farm-out secured, and the seismic reinterpreted, the company now stands on the threshold of delivery. The years of exploration, frustration, and patience are about to give way to a new reality: first gas from Ntorya.

The foundations are already being laid:

• The Central Processing Facility (CPF) soon under construction, designed to handle volumes far beyond anything Kiliwani ever produced.

• A dedicated pipeline to Madimba will connect Ntorya directly into Tanzania’s national grid.

• The upcoming Chikumbi-1 (CH-1) well is set to provide the final data, confirming reserves and opening up deeper horizons.

For Aminex shareholders, the prize is tangible. With a 25% free-carried interest, the company is positioned to receive an expected $40 million net cashflow per annum once the Ntorya field is on stream. That’s not blue-sky speculation — it’s a contracted pathway underpinned by infrastructure already in build.

For Tanzania, Ntorya is about more than cashflow. It’s about energy security, powering industry, and supporting economic growth with domestic supply. Aminex’s journey from a struggling junior to a long-term gas partner mirrors the country’s own transition toward energy independence.

---

So the oak tree has not yet fully spread its branches, but the trunk is strong, the roots are deep, and the first harvest is within reach.

➡️ The story continues. The next RNS will write the next page — and when first gas flows from Ntorya, Chapter Eleven will begin.

Why the Aminex Ntorya CPF Remains Critical — Even with a Raw Gas Pipeline to Madimba

Why Ntorya still needs a CPF—explaining the critical role of field-level gas treatment before transport to Madimba via the raw pipeline.

Following questions about the need for a Central Processing Facility (CPF) at Ntorya — after it became known that the pipeline to Madimba is a raw natural gas pipeline — further investigation confirms that the CPF remains a critical component of Tanzania’s two-stage gas infrastructure.

Understanding the true function of a “raw” pipeline clarifies the issue.

---

What Is a Raw Pipeline?

In industry terms, a raw natural gas pipeline — also known as a gathering line — transports unprocessed gas from wellheads to a processing plant. This gas can include water, condensates, sand, carbon dioxide, and other impurities. These pipelines are typically lower-pressure, shorter-distance systems designed to collect gas before it is made pipeline-quality.

In contrast, a natural gas transmission pipeline carries fully processed, dry gas over long distances at high pressures to power stations, cities, and industries.

The planned pipeline from Ntorya to Madimba fits squarely into the “raw pipeline” category: it connects a producing field to a processing plant. But it does not remove the need for initial gas conditioning before transport.

---

Why the CPF Is Still Essential

The CPF (Central Processing Facility) at Ntorya performs field-level processing that is critical to both safety and system efficiency:

1. Protecting the Pipeline

• Raw gas straight from the well can contain sand, water, and condensates.

• These materials are highly corrosive and abrasive, and transporting them through 30–35 km of steel pipeline without separation can lead to blockages, corrosion, and operational failures.

2. Compression for Flow

• The CPF compresses the gas to the correct pressure for transport to Madimba.

• Without compression, gas may not flow reliably over the required distance, especially as volumes scale.

3. Dehydration & Impurity Removal

• Moisture in gas can condense and form hydrates in the pipeline — a major flow assurance issue.

• The CPF dehydrates the gas and removes solid or liquid impurities to meet minimum entry standards for transport.

---

What Happens at Madimba?

The Madimba Gas Processing Plant, located near Mtwara, is a central hub in Tanzania’s national gas system. It performs:

• Final purification: Removal of CO₂, acid gases, and any residual water.

• Blending: Mixing gas streams from Ntorya, Songo Songo, and Mnazi Bay.

• Metering & Dispatch: Delivering pipeline-grade gas into the national transmission system.

Madimba expects partially treated gas, not unfiltered output from a wellhead. Its infrastructure is not designed to manage raw contaminants at scale — that is the role of the CPF.

---

Industry Standard Practice

Globally, two-stage gas processing is the norm:

1. Field-Level CPF: Performs initial treatment, especially of liquids, sand, and basic impurities.

2. Processing Plant: Conducts final conditioning and prepares gas for transmission.

Trying to send untreated gas directly from a wellhead to a central plant 30+ kilometers away is a shortcut that risks damaging infrastructure, reducing uptime, and ultimately impacting commercial viability.

---

Conclusion: The CPF Is the Enabler, Not a Redundancy

The fact that a raw gas pipeline connects Ntorya to Madimba does not make the CPF optional — in fact, it reinforces its necessity. The CPF ensures that:

• Gas flows efficiently and safely through the raw pipeline.

• Infrastructure integrity is protected from corrosive and abrasive elements.

• Ntorya can scale up production with operational stability and minimal risk.

In simple terms: the CPF is not bypassed by the raw pipeline — it feeds it. Together, they create a robust, flexible, and expandable gas delivery system for Tanzania’s future energy needs.

From Seismic to Supply: The Ntorya–Madimba Gas Pipeline

A Chronological Overview: Aminex Pipeline (Ntorya–Madimba Project)

Here's a detailed, timeline-based summary of the developments surrounding the Aminex-backed Ntorya–Madimba gas pipeline:

1. Planning & Seismic Survey (Early 2025)

• In early 2025, Aminex and its operator ARA Petroleum Tanzania (APT) formulated an updated Field Development Plan (FDP) for Ntorya, based on results from a comprehensive 3D seismic campaign. This informed a phased development strategy to scale production from ~60 MMscf/d up to 280 MMscf/d through additional drilling over time.

• In October 2024, TPDC issued a restrictive tender for engineering, procurement, and construction (EPC) services for the pipeline.

2. Strategic Agreements & Pipeline Planning (2024)

• Aminex secured a gas sales agreement, and the Development License award paved a clearer path toward monetization.

• The Ntorya-to-Madimba pipeline was positioned as a monetization trigger—a vital channel to realise commercial production.

3. Engineering & Construction Preparations (First Half of 2025)

• On 3 July 2025, TPDC awarded the EPC contract to a consortium of China Petroleum Pipeline Engineering Co., Ltd. (CPP) and China Petroleum Technology & Development Corporation (CPTDC).

• By 14 July 2025, TPDC formally handed over the project site to the contractors, enabling them to start site investigations, detailed engineering, and design.

4. Construction Start & Timeline Confirmation (Mid 2025)

• In July 2025, Aminex confirmed that pipeline construction would commence that same month, aiming for completion by July 2026. The Ntorya‑2 well would begin supplying gas once the pipeline was operational.

• A corporate presentation highlighted these milestones along with strategic contractors being in place, reinforcing the pipeline’s imminent delivery and its integration with national gas infrastructure.

5. Drilling & Tendering Activities (Mid to Late 2025)

• Aminex/ARA presented a tender strategy to PURA for drilling the Chikumbi‑1 (CH‑1) well and executing the Ntorya‑1 (NT‑1) workover. PURA approved this, and APT planned to issue tenders by mid‑August 2025.  The ten day time limit for EOI's ended over the weekend so it can be assumed they are now doing their due diligence on the interested parties.

6. Operations Update & Mobilization (August 2025)

• As of 27 August 2025, TPDC informed the joint venture that:

  • Pipeline procurement had begun.

  • Equipment mobilization would start in September 2025.

  • Groundwork and pipe laying were scheduled from January 2026, with completion by July 2026.

  • Discussions on condensate processing and storage were underway.

  • PURA had approved the expedited tender process for drilling and well services.

Ntorya Gas: The Hidden Backbone of Tanzania’s Energy Revolution

Why Aminex’s 25% stake in a $5.3B asset is massively undervalued—and essential to powering East Africa’s future.

Tanzania is at a crossroads of transformational change. With one of the fastest-growing populations in Africa, a government-led industrialisation push, and mounting regional energy demand, the country is setting the stage to become East Africa’s energy hub.

At the heart of this vision is the Ntorya Gas Field—a resource-rich onshore gas field discovered by Aminex plc (AEX: AIM) now in partnership with operator ARA Petroleum. While most headlines focus on offshore LNG megaprojects, Ntorya is quietly becoming the real enabler of near-term, high-impact development across power generation, clean cooking, and industrial expansion.

---

🛢️ What Is Ntorya and Why Is It Crucial?

Located in Tanzania’s Ruvuma Basin, Ntorya is a discovered and appraised onshore gas resource with independently certified 2C resources of 3.45 TCF (trillion cubic feet). It is strategically located close to existing infrastructure:

• ~35 km to the Madimba Gas Processing Plant (connected to the national grid)

• Within reach of industrial zones, power plants, and LPG bottling networks

• Tied to the government’s pipeline construction timeline, now under execution

In July 2025, TPDC awarded a contract to Chinese EPC firms for the Ntorya–Madimba pipeline, aiming for first gas by July 2026.

---

🚀 The Demand Side: Powering Growth and Decarbonisation

1. Electricity for a Growing Nation

Tanzania’s demand for electricity is surging, driven by:

• Industrial expansion (Kwala, Bagamoyo, Mtwara, and 5 new SEZs)

• Urbanisation and regional electrification (Kenya, Uganda, Zambia interconnectors)

• Replacement of expensive diesel generators in off-grid and peri-urban areas

Gas-fired power is a vital component of Tanzania’s Least Cost Power Development Plan, offering a flexible, cleaner alternative to coal and hydro. Ntorya’s gas could support:

• Mtwara’s planned 600 MW gas-fired plant

• Power exports via the Zambia–Tanzania interconnector (commissioning by 2026)

• Stability for the growing SEZ clusters

2. Clean Cooking Revolution

Over 85% of Tanzanians still cook with wood or charcoal, causing:

• Massive deforestation (est. 400,000 hectares lost annually)

• Respiratory diseases linked to indoor air pollution

• Lost productivity and gender-based labour burdens

The government’s Clean Cooking Energy Strategy 2024–2034 aims for 80% adoption of clean cooking solutions by 2034, with LPG and piped gas forming the backbone.

Ntorya—via processing at Madimba and planned bottling/distribution networks—could become a critical feedstock for LPG, accelerating this health and environmental imperative.

---

🏭 Ntorya + Infrastructure: Perfect Alignment

The Tanzanian government is making record infrastructure investments, many of which require reliable gas supply:

Infrastructure Project	How Ntorya Supports It
Kwala Industrial Zone (2,000+ industries)	Pipeline link via Chalinze branch
Dar–Chalinze 102 km pipeline	Extends gas grid northward
Mtwara Corridor industrial sites	Direct proximity; gas-fuelled plants
Bagamoyo port/SEZ (700+ industries)	Industrial and export energy needs
5 new SEZs (TISEZA, Aug 2025)	Manufacturing zones require consistent gas/power

This infrastructure is not just domestic—Tanzania is now deeply tied into regional energy trade, with long-term plans for a Dar–Mombasa gas pipeline, power interconnectors to Uganda and Zambia, and LPG exports to neighbouring countries.

---

💰 Aminex’s Ntorya Stake: A Multi-Billion-Dollar Revenue Stream in the Making

📦 Step 1: How Much Gas is 0.4 Tcf?

• 1 Tcf = 1 trillion cubic feet

• Aminex’s net discovered share: 0.4 Tcf

• In Mcf (thousand cubic feet):
  0.4 Tcf = 400 million Mcf

---

💵 Step 2: Apply Realistic Price Scenarios

Price Scenario	Mcf Value	Gross Revenue
Base Case	$4.00/Mcf	$1.6 billion
Higher Case	$6.10/Mcf	$2.44 billion

Even under conservative pricing, Aminex’s gas could generate $1.6 billion in gross sales over its production life — rising to $2.44 billion using industry tariff averages.

This isn’t speculative: the Gas Sales Agreement (GSA) is signed, and Ntorya’s gas is destined for guaranteed demand through:

• Madimba Gas Plant

• Tanzania’s national grid

• Industrial zones like Kwala and Bagamoyo

---

🧾 Step 3: What Does That Mean for Aminex?

While gross sales ≠ net profits, the exercise highlights one thing:

This is a multi-billion-dollar gross revenue stream backed by infrastructure, policy, and market need.

Factors such as:

• The Production Sharing Agreement (55–60% government take),

• Ongoing cost recovery (capex/opex), and

• Multi-year revenue timing

…will shape exact returns. But even adjusted for PSA terms, Aminex’s upside remains enormous.

---

📊 Step 4: How It Compares

For context:

• Orca Exploration (operating in Tanzania’s Songo Songo field) averaged over $6/Mcf in 2023 gas sales.

• This validates the $6.10/Mcf industrial pricing used in our high case.

So Ntorya gas is likely to achieve higher-tier pricing, not just the base GSA rate — making the higher revenue scenario entirely realistic.

---

🔍 Conclusion: Massive Value, Still Mispriced

With a current market cap around $100 million, Aminex is trading at:

• ~6% of potential gross revenue at base pricing

• ~4% of potential gross revenue at industrial pricing

This level of undervaluation—on a de-risked, demand-backed, GSA-approved, development-ready gas asset—is extraordinary.

As the Ntorya–Madimba pipeline moves toward first gas in 2026, investors have a rare asymmetric opportunity to enter a project with scale, timing, and strategic alignment fully in place.

---

🌍 ESG & Energy Transition: A Stronger Investment Narrative

Ntorya is not just a resource—it’s a climate-aligned, impact-driven energy project. It:

• Displaces biomass and diesel with cleaner, reliable gas

• Supports health, education, and gender equity through clean cooking

• Boosts Tanzania’s ability to trade energy regionally and grow sustainably

For impact funds, ESG-aligned investors, or frontier energy portfolios, Ntorya offers high upside with positive social and environmental impact.

---

🧠 Final Thoughts: Ntorya Is Not Optional—It’s Foundational

Tanzania’s bold industrial, electrification, and clean cooking goals depend on gas that’s already discovered, already financed, and already being built.

Ntorya is:

• Strategically located

• Nationally prioritized

• Technically de-risked

• Financially undervalued

As first gas approaches in 2026, and pipeline works begin in earnest, the clock is ticking on this unique asymmetrical opportunity. For investors willing to look beyond the offshore LNG fog, Ntorya and Aminex offer clarity, impact, and returns.

Aminex RNS: Ntorya Operations Update Confirms Pipeline and Rig Milestones

Procurement for the Ntorya–Madimba pipeline begins, groundwork scheduled for January, while PURA approves the rig tender strategy.

---

Key Highlights from Today’s RNS

• Pipeline Progress:

  • Contractors have begun procurement of pipe and equipment for the 35 km pipeline linking Ntorya to the Madimba gas processing plant.

  • Mobilisation of construction equipment will begin in September 2025.

  • Groundwork and pipelaying are scheduled to commence in January 2026, with completion targeted by July 2026.

• Condensate Value Addition:

  • Discussions are under way regarding the processing and storage of condensate volumes from Ntorya — an additional revenue stream beyond gas sales.

• Rig Tender Milestone:

  • The Petroleum Upstream Regulatory Authority (PURA) has approved the tender strategy for contracting a drilling rig.

  • The rig will be used to drill Chikumbi-1 (CH-1) and perform a workover on Ntorya-1 (NT-1).

  • Operator APT will request expressions of interest from service contractors next week.

---

Why This Matters for Investors

This RNS confirms that multiple strands of Ntorya’s development are advancing in parallel:

• Pipeline: With procurement already under way and a firm mobilisation schedule, the long-discussed link to Madimba has moved from planning to delivery. A clear timeline to completion by July 2026 provides investors with visibility.

• Rig Tender: PURA’s approval is a regulatory green light that allows the operator to advance into contractor engagement. The drilling of CH-1 and the NT-1 workover will expand production capacity beyond NT-2, underpinning volumes for the GSA.

• Condensate: Monetisation of condensate offers upside beyond gas sales, increasing the value of the project.

Together, these steps strengthen confidence that Ntorya is firmly on its way to first gas, with strong backing from TPDC, PURA, and APT.

---

Aminex Management Comment

Charles Santos, Executive Chairman, highlighted:

“Our discussions with the TPDC and the operator have been extremely fruitful, and we are delighted that activity on the Pipeline is proceeding as planned… PURA has approved the tender strategy, allowing APT to begin the tender process. These developments demonstrate again the Government of Tanzania’s strong commitment to this project.”

---

Investor Takeaway

This update provides:

• Visible progress on the pipeline, with equipment procurement already started.

• Firm dates for mobilisation (Sept 2025), groundwork (Jan 2026), and completion (July 2026).

• Regulatory approval clearing the way for the rig tender and the next phase of drilling.

• Condensate upside adding to the project’s revenue profile.

For shareholders, this RNS delivers the clearest evidence yet that Ntorya’s development is advancing on multiple fronts, backed by Tanzania’s institutions and operator commitment.

Ntorya Aminex ARA First Gas: Pathways to Production

How multiple wells and facilities could support the journey to first gas at Ntorya.

---

A Project Moving Forward

The Ntorya development in southern Tanzania continues to progress toward its goal of delivering gas into the national grid via the new 30 km pipeline to Madimba. With approvals, budgets, and land acquisition in place — and procurement of key facilities already under way — the project is steadily advancing along its critical path.

---

The Role of NT-2

Public updates to date have consistently named NT-2 as the first well scheduled to deliver gas into the new system. Flowline rights of way have been secured, and the well is expected to be ready in line with pipeline completion.

NT-2’s early contribution would demonstrate that the infrastructure works as designed and confirm the start of Ntorya’s commercial life.

---

Beyond NT-2: The Next Wells

While NT-2 is the immediate focus, there is a broader plan:

• CH-1 (Chikumbi-1): a new well to be drilled with a conventional rig.

• NT-1 Workover: returning one of the earlier discovery wells to production using the same rig once CH-1 is complete.

Land has already been acquired for the CH-1 pad, and all tubulars and wellhead equipment are ready. Regulatory agencies have indicated that they want the rig tender expedited — underlining the importance of getting CH-1 and NT-1 online quickly after NT-2.

---

Processing Facilities and Flowlines

The approved US$41 million development budget includes:

• The Central Processing Facility (CPF) at Ntorya,

• Flowlines and hook-ups for NT-1 and NT-2,

• Gathering manifolds and fiscal metering.

This confirms that full upstream facilities are part of the current phase — not just temporary or mobile systems.

---

Looking at Possible Scenarios

Based on information released so far, there are several possible ways the project could unfold:

1. NT-2 First Gas – As officially stated, NT-2 comes online first, delivering initial volumes into the CPF and pipeline.

2. Reinforcement from CH-1 and NT-1 – These wells follow rapidly, ensuring that contractual volumes are comfortably met and sustained.

3. Parallel Build-out – NT-2 begins the process, while CH-1 and NT-1 are accelerated to underpin production, giving the field multiple producing sources from an early stage.

All three scenarios lead to the same outcome: Ntorya gas flowing into the Madimba plant and on into the national grid.

---

Why This Matters for Investors

For investors, the key message is that Ntorya is not reliant on a single well. The project is structured with multiple paths to delivery, a fully funded facilities budget, and strong government support for expediting the programme.

Whether first gas flows solely from NT-2 or from a combination of NT-2, CH-1, and NT-1, the end result is the same — a producing gas field with infrastructure in place and a guaranteed market under the Gas Sales Agreement.

---

Closing Thought

Ntorya’s journey to first gas is not a straight line but a set of carefully managed options. That flexibility is a strength, giving the operator and Tanzania’s energy system more than one way to reach the finish line.

For investors, it is reassurance that the project has the resilience and scope to meet its commitments and deliver on its long-term promise.

Aminex ARA From Field to Grid: Ntorya’s CPF and the Madimba Plant

 

How Tanzania’s two-stage gas system takes Ntorya’s production from the wellhead all the way to homes, power stations, and industry.

---

The Two Key Facilities

When Ntorya comes on stream, two plants will play essential but different roles in the journey of its gas. Understanding their functions helps investors see how the system is designed for both safety and scale.

---

1. The Ntorya CPF — Field-Level Processing

• Location: At the Ntorya well cluster.

• Role: First-stage treatment, making raw gas suitable for pipeline transport.

• Functions:

  • Separation of gas, water, and condensates.

  • Removal of impurities (sand, liquids).

  • Dehydration to meet pipeline standards.

  • Compression to flow into the 30 km export line.

• Capacity: Designed initially for ~40 MMscf/d, expandable toward 140–280 MMscf/d.

The CPF ensures Ntorya gas leaves the field safely and efficiently.

---

2. The Madimba Gas Processing Plant — National Hub

• Location: Near Mtwara, on Tanzania’s southern coast.

• Role: Central treatment and distribution point for southern Tanzania’s gas.

• Functions:

  • Final treatment (removing CO₂, acid gases if present).

  • Metering and blending streams from different fields (Songo Songo, Mnazi Bay, Ntorya).

  • Dispatching gas into the national pipeline grid.

• Capacity: ~210 MMscf/d, expandable.

Madimba ensures gas from multiple sources is blended, metered, and delivered into the grid — powering electricity generation, industries, and domestic users.

---

Why Both Are Needed

• The CPF is field-specific — treating Ntorya gas at the source.

• Madimba is system-wide — combining streams and delivering national supply.

• Together, they provide a two-stage assurance: first, that Ntorya gas meets quality standards at source; second, that it is integrated seamlessly into Tanzania’s energy network.

---

Investor Perspective

• The CPF is the critical path asset for Ntorya first gas.

• Madimba is the assurance of market access — guaranteeing that once Ntorya flows, there is infrastructure ready to take it.

• This dual system significantly reduces market risk: gas has both a path and a destination.

Flowlines at Ntorya: How Wells Connect to the CPF

The smaller pipelines that quietly connect Ntorya’s wells to the Central Processing Facility — and why they matter for investors.

When investors picture Ntorya, they often think of the big pieces — the wells and the 30 km export line to Madimba. But the flowlines — the smaller pipelines that run from each well to the Central Processing Facility (CPF) — are just as vital. Without them, gas can’t move from the ground into the plant that prepares it for market.

---

What are flowlines?

Flowlines are short, steel pipelines laid mostly underground. Each one links a wellhead (NT-1, NT-2, CH-1 and the future drilling programme) to the CPF. At the CPF, the streams are combined, processed, and sent onwards through the export pipeline.

Think of them as the capillaries of the system: not as big or visible as the main artery to Madimba, but essential for delivering every molecule of gas to the plant.

---

How do they tie in?

• At the wellhead: each producing well has a “Christmas tree” — the set of valves and fittings on the surface. From there, a flowline connection carries the gas into the ground and runs toward the CPF.

• At the CPF: the lines converge into a small gathering manifold. From this header, gas enters the first separator at the CPF where liquids, water, and impurities are removed.

In some developments, nearby wells can be “clustered” into a shared line before reaching the CPF. At Ntorya, with up to 14 wells planned over the licence life, that decision will depend on final well locations and drilling sequence.

---

How big are the flowlines?

For individual wells producing in the 8–20 million cubic feet per day (MMscf/d) range:

• Flowlines are typically 4 to 6 inches in diameter.

• Over short distances (2–6 km), this size keeps pressure loss small and allows for internal inspection (“pigging”).

• At the CPF, the combined flows enter a slightly larger 6–8 inch gathering header before processing.

For context, the main export pipeline to Madimba will be much larger — designed to carry 140 to 280 MMscf/d over 30 km.

---

How are flowlines installed?

• Surveying & Right-of-Way: pegging a safe route across farmland and bush.

• Trenching: digging a narrow trench, usually 1–1.5 m deep.

• Stringing & Welding: laying out pipe sections, welding, inspecting, and coating.

• Lowering & Backfilling: placing the welded line into the trench and carefully covering it over.

• Testing: filling with water and pressure-testing before first gas.

This is the same method used worldwide for gathering systems, adapted for local conditions in southern Tanzania.

---

Why this matters for investors

• Scalability: Each new well drilled can be tied in with its own flowline, building toward the 14-well, 140–280 MMscf/d target.

• Visibility: Installation of flowlines is one of the most visible signs of progress — a physical link between the subsurface resource and the CPF.

• Low risk technology: Flowline construction is proven, straightforward engineering with limited execution risk compared to drilling or CPF build.

• Cost efficiency: Smaller lines keep costs controlled, while future connections can be phased in as production ramps up.

---

Closing thought

Flowlines don’t often make headlines. But they are the practical step that brings every new Ntorya well into the system. As more wells are drilled, each flowline tied into the CPF is another visible sign that Ntorya is moving steadily from promise to production.

For investors, watching the progression of well → flowline → CPF → export pipeline is the clearest way to track momentum toward first gas.

Ntorya’s Central Processing Facility: What It Is and Why It Matters

Practical steps from wellhead to Madimba — what could happen next

When people think of Ntorya and Aminex, they picture wells and a pipeline. The Central Processing Facility (CPF) is the part in the middle that makes everything work. It’s where raw gas from the wells is prepared so it can safely and reliably enter the line to Madimba.

What a CPF does

At a high level, a CPF separates, conditions and compresses the gas:

• separates water and liquids,

• dries/conditions gas to pipeline specs,

• compresses it so it can flow to Madimba.

How it connects to the wells

Each producing well (e.g., NT-1, NT-2, and CH-1) would be linked to the CPF by flowlines. The CPF combines these streams into a single, spec-gas export to the main pipeline. Capacity can be phased so more wells can be added over time.

Where it could be located

Public information points to a location within the wider Nanguruwe/Ntorya ward area so that flowlines are short and road access is sensible. The exact plot is typically confirmed through regulatory steps and company notices; until then, it’s reasonable to assume siting close to the existing well cluster and on a clean line of route toward Madimba.

About testing and why it matters

A mobile test on NT-2 has been discussed to help fine-tune the processing set-up (for example, dehydration and compression requirements). Final equipment specification would normally reflect those test results. In parallel, enabling works at the CPF site (groundworks, civils, fencing, early foundations) can progress ahead of final kit selection, with long-lead equipment orders typically following once test data and approvals are in hand.

Schedule at a glance (indicative)

Subject to approvals and site conditions:

• Site preparation could proceed first (weeks to a few months).

• Equipment procurement and installation would typically follow confirmatory testing/approvals.

• Commissioning would then align with pipeline readiness so first gas can move without delay.

Team and logistics (typical ranges)

Based on similar onshore projects, peak on-site teams can be around 100–200 people, spanning civil, mechanical, E&I and commissioning, with local support for catering, logistics and security. Actual numbers vary with phasing and contractor strategy.

Budget context

Company guidance indicates the approved upstream facilities budget for this phase is intended to cover the CPF plus associated tie-ins, flowlines, manifolds and metering. Exact allocations are usually confirmed in subsequent updates and may be adjusted as testing and procurement progress.

Could start-up be modular?

Yes. A CPF can be delivered in modular packages (skid-mounted separation, dehydration and compression). This approach could enable phased start-up at lower initial rates while full capacity is built out, subject to approvals and commercial agreements.

Bottom line for investors
The CPF is the critical enabler between wells and pipeline. Enabling works may proceed while test results and approvals are finalised, and a modular, phased approach could support an earlier start if required. As company updates arrive (testing schedules, procurement awards, and first-weld milestones), they should help de-risk the timeline and confirm the path to first gas.

This article reflects current understanding and may evolve as formal notices and approvals are published.

From Field to Flame: Building the Ntorya–Madimba Gas Link

 

Charting Tanzania’s Next Step in Energy Security and Growth

When Tanzania granted a 25-year development licence for the Ntorya gas field, it marked the beginning of a project with national importance. Ntorya, in the Ruvuma Basin, contains multi-trillion cubic feet of natural gas and will be the source for the new 30 km pipeline linking it directly to the Madimba processing plant on the coast.

This isn’t just about steel in the ground. It’s about unlocking energy security, creating jobs, and building a long-term framework that rewards both the country and the companies developing the resource.

---

1. Preparing the Source – Ntorya Field

Before gas can flow, the operators (ARA Petroleum Tanzania and Aminex/Ndovu) must:

• Drill and complete new production wells.

• Install wellhead equipment and flowlines.

• Build a central processing facility (CPF) to clean, condition, and compress the gas.

The CPF is the key that unlocks the project — the point where the raw resource becomes a reliable supply stream.

---

2. Where the Pipeline Begins

Because the Madimba gas plant already exists, construction of the new line is expected to start from the coastal end.

• Crews will mobilise at Madimba where access roads, storage yards, and metering facilities are already in place.

• A second team will move outward from Ntorya, preparing the line toward the centre.

• The two spreads will eventually meet with the “golden weld” that completes the system.

This staged approach means visible progress at the coast, while upstream facilities at Ntorya are finalised.

---

3. Surveying, Trenching, and Welding

Once the route is cleared:

• Surveyors peg the line.

• Trenches are cut into farmland and bushland with environmental care.

• Pipes are strung out, welded, x-rayed, and coated.

• Sections are lowered into place and backfilled with soil.

---

4. Compression, Metering & Safety

• At Ntorya, the CPF compresses gas into the line.

• Along the route, valve stations provide monitoring and emergency shut-off capability.

• At Madimba, a metering station ensures accurate accounting under the Gas Sales Agreement (GSA).

---

5. Testing & Commissioning

Before any commercial flow:

• The pipeline is hydrotested with high-pressure water.

• Sensors and inspections check integrity.

• Regulators certify the system for use.

---

6. First Gas & Growth Path

The agreed sales profile provides certainty:

• Initial 40 MMscf/d in the first contract year.

• Expansion toward 140 MMscf/d in later years as infrastructure ramps up.

This structured growth path allows investors to see immediate revenue with clear upside capacity.

---

7. Why It Matters

• Certainty of Market: The GSA with TPDC guarantees offtake.

• Government Alignment: Tanzania has amended the PSA and committed to building the link to Madimba.

• Long-Term Stability: A 25-year licence underpins project economics.

• National Impact: Jobs, community engagement, and new energy supplies for southern Tanzania.

Closing Thought

The Ntorya–Madimba pipeline is more than an engineering project — it’s a strategic bridge. It links the resource potential of the Ruvuma Basin with the processing power of Madimba and the demand of the national grid.

For Tanzania, it secures energy and economic growth.
For investors, it offers a project with clarity, alignment, and visible momentum.
