Royal
Dutch Shell plc & BG Group plc Kick off the Oil & Gas Mergers &
Acquisitions Mega Season
Why
Tanzania was so important in this deal and what could it mean for the massive
Ruvuma onshore gas field & Solo Oil
“If you base the
TCF valuation on the same benchmark as the Ophir-Pavilion deal where Pavilion
paid $353 million per TCF for its 20% stake in Tanzania’s offshore blocks
1,3,4, then Ruvuma would be valued on an un-risked basis (1.17tcf) at $413
million minimum but on 2.3 tcf (Aminex plc LON:AEX resource estimate for
Ruvuma) of $811 million. Solo Oil Plc LON:SOLO own 25% of the Ruvuma PSA.
Accordingly the value attributable to Solo Oil plc could be anywhere between
$100 million to $200 million, and remember the Ntorya well in the Ruvuma PSA
has pipeline infrastructure nearby and is an advanced project that can get into
production very quickly.”
When BG Group plc LON:BG announced in August 2014 that it
had produced higher than
expected flows of gas from their Mzia-3 test well off
the southern part of Tanzania’s coast, it was news that must have caught the
eye of Royal Dutch Shell plc LON:RDSA
Mzia-3 was not only producing better than expected
results, but it was reaching a flow rate of 101 million cubic feet per day,
nearly double the flow rate measured at their Mzia-2 well that had test flowed
a year earlier.
The impressive flow rates served to boost the financial
viability of BG Groups planned Tanzanian LNG terminal and associated upstream
production facilities and infrastructure, a factor that must have also
interested Royal Dutch Shell plc.
Shell’s decision to buy BG Group plc was one that focused
on long-term asset building. It has enabled the company to get access to BG
Groups significant advanced exploration portfolio. BG Group plc had sunk huge
capital into the ground. This is where Shell clearly saw the long-term value in
this mega deal.
However, we feel it is access to Tanzania that featured
as a major factor in the purchase of BG Group, given Shell ended a £1.12bn cash
offer for Cove Energy back in 2012 which was designed to give the company a
foothold in east Africa’s gas sector, that attempt sadly failed.
Royal Dutch Shell’s major African continent gas projects
are located primarily in west Africa, not ideal in terms of shipping logistics
to the Asia market. Shell were fully aware of the gas potential in Tanzania. In
2002, the company won a Tanzania Petroleum Development Corporation tender for
four offshore blocks around Zanzibar island, but the deal got blocked by the
Tanzania government. Shell holds at least four exploration licenses off
Zanzibar and is working with Petroleo Brasileiro SA on two off Tanzania. But it
is the legal process of essentially two jurisdictions, Zanzibar and Tanzania
that has served to hold up Shell’s progress offshore.
BG Group LON:BG entered Tanzania in 2010 and is the
operator of offshore Blocks 1, 3 and 4 in which it has a 60% interest. Around
15 tcf of total gross resource has been discovered and work is progressing to
develop a joint LNG plant in collaboration with the Block 2 partners. Mzia was
confirmed as second giant gas discovery, after Jodari, other highlights include
- Taachui gas discovery secured in Block 1
- LNG site MoU signed with the government
- HoA signed with Block 2 partners: BG Group is lead developer for pre-FEED
- Contracts for upstream and LNG plant pre-FEED have already been awarded.
Putting this into
context
Why Ruvuma must
now be a major acquisition interest.
Back in November 2013, Ophir Energy (LSE:OPHR) announced
the sale of 20% interest in Tanzania blocks 1, 3 and 4 to Pavilion Energy for a
staggering $1,288 million. The transaction with Pavilion a wholly owned
subsidiary of Temasek, the Singapore investment company, served as one of the
most important pricing benchmarks for Tanzania’s hydrocarbon sector.
With the most recent gas discovery on the Kamba-1 well in
Block 4, the total discovered gross 2C resource to date is estimated at 17.1TCF
across the three blocks, which is enough to underpin a two train LNG
development.
So essentially Pavilion
paid $1.2 billion USD for 3.4 TCF or $353 million per TCF
It was also a deal that showed the strategic importance
Asia investors are placing on Tanzania in respect of its huge gas export
potential. Given that the season for mega deals is now underway and why
Tanzania is featuring at the centre stage of mega deal making once again, I
think it is time to remind investors about Tanzania’s massive Ruvuma gas field.
The Ruvuma PSA originally covered 12,360 square
kilometres in the extreme south-east of Tanzania of which roughly 80% is
onshore and 20% offshore. This is a licence development area that was awarded
back in 2005. Ten years of work has been undertaken on Ruvuma.
Within the PSA are two specific, adjoining licence areas,
known as Lindi and Mtwara. Following the first exploration period and an
extension about 75% of the area was relinquished and the remaining PSA covers
3,447 square kilometres. Prior to the award of the current PSA 1153 kilometres
of 2D seismic had been acquired in the area of the PSC between 1981 and 2002.
No wells had been drilling within the boundaries of the PSA, but a well at
Lukeledi-1 to the north had been drilled by Texaco in 1992 and the Mnazi Bay-1
well to the southeast had been drilled by Agip in 1982. Following award of the
PSA Ndovu Resources, a subsidiary of Aminex plc, acquired 370 kilometres of
offshore seismic in the Lindi Block and a further 430 kilometres of 2D seismic
onshore in the Lindi and Mtwara Blocks.
The first well under the Ruvuma PSA was drilled in 2010
on the Likonde prospect. Likonde-1 is located in the Lindi Block and
encountered thick sands with hydrocarbon shows. The well was drilled to a total
depth of 3,647 metres and results of drilling, wireline logs and side-wall
coring showed that the well intersected two sandstone intervals of over 250
metres (820 feet) combined thickness with evidence of residual oil and gas.
Drilling had to be terminated in the deepest objectives due to the high rate
influx of gas.
Based on the encouraging results of the Likonde-1 well
the available 2D seismic was reprocessed and reinterpreted to select the
location for a second exploration well, within the Mtwara Block. The chosen
location, Ntorya-1, was intended to target the updip extent of the sands
encountered in the Likonde-1 well.
On the 6 October 2011, prior to the drilling of Ntoya-1,
Solo Oil plc announced that it has increased its stake in the Ruvuma Basin PSA
from 12.5% to 18.75% by assuming the additional obligations associated with the
additional interest relinquished by Tullow Oil who reduced their over holding
from 50 to 25%.
Ntorya-1 was spudded on the 22 December 2011 and
intersected a gross 25 metre section of Mid-Cretaceous sandstones with gas. The
upper 3.5 metres of the gas bearing zone were tested at a maximum rate of 20.1
mmscfd with 139 barrels oil per day of 53 deg API condensate through a 1”
choke. The flow rate was considered to be of potential commercial interest and
well has been suspended.
After intersecting the primary target, but prior to
deepening to the eventual discovery level in the Ntorya-1 well Tullow Oil plc
LON:TLW elected to transfer their remaining 25% interest to the partners, Ndovu
and Solo Oil in proportion to their existing interests in return for the
assignees accepting future obligations in the second exploration period. As a
result Solo increased its interest in the Ntorya-1 discovery and the Ruvuma
Basin PSA to 25%.
A resource report has been prepared by ISIS Petroleum
Consultants that attributes 5.75 tcf of potential gas-in-place resources to the
Ruvuma PSA. ISIS calculates that Ntorya holds mean 1.17 tcf of unrisked gas in
place of which 178 bcf are considered discovered, but recently increased its internal resources estimate of Ruvuma to 2.3
tcf.
“If you base the
TCF valuation on the same benchmark as the Ophir-Pavilion deal where Pavilion
paid $353 million per TCF for its 20% stake in Tanzania’s offshore blocks
1,3,4, then Ruvuma would be valued on an un-risked basis (1.17tcf) at $413
million minimum but on 2.3 tcf (AMINEX plc LON:AEX resource estimate for
Ruvuma) of $811 million. Solo Oil plc own 25% of the Ruvuma PSA. Accordingly
the value attributable to Solo could be anywhere between $100 million to $200
million, and remember the Ntorya well in the Ruvuma PSA has pipeline infrastructure
nearby and is an advanced project that can get into production very quickly.”
The Ntorya-1 discovery is now the subject to an
application for an appraisal extension to the licence to carry out a two-year
program of additional infill seismic and a further well. Elsewhere in the PSA
an additional seismic program and two additional exploration wells are planned
to follow-up the success of the first two wells. It is anticipated that a
farm-in partner will be found to take up to a 50% interest in return for a
substantial financial contribution to the remaining work program.
Essentially
Ruvuma’s gas reserves equate to approximately 30% of BG Group’s stated Tanzania
gas asset reserves. For Asia investors that want access to near term lower risk
onshore gas production, then snapping up Ruvuma would be a very wise move.
Solo’s shares shot
up last week on the back of the major oil reserve upgrade by the Horse Hill
Development consortia, where they own 6.5% interest in the Horse Hill-1 well.
But we suspect the
biggest value catalyst for Solo Oil plc after their Kiliwani well enters production
this year, will be Ruvuma.
