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.

What's Next? Looking Ahead
-
January to July 2026: Ground breaking phased construction, leading to completion and commissioning of the pipeline.
-
Shortly after pipeline commissioning: Chikumbi‑1 drilling and Ntorya‑1 workover, with Ntorya‑2 revenue poised to start.
-
Mid‑2026 and beyond: First gas deliveries to Tanzania’s domestic market, gradually expanding towards full-scale production (~280 MMscf/d) and condensate integration.
