Angolan Rig Count Drops

The number of rigs actively drilling on locations in Angola has fallen to 18 in November, from 22 in September 2015, according to the November 2015 edition of the Africa Oil + Gas Report.

Chevron and TOTAL have dropped one rig each, while ExxonMobil increased its rig count by 1. Cobalt has finished drilling on Block 21 and released the rig. ENI retains the two rigs it had last September.

The busiest company at the drill bit remains Chevron.

Full details of who is drilling what and where in Angola is available to paying subscribers of the monthly edition of the Africa Oil + Gas Report.


Shell Encounters Two Deeper Pool Gas Sands In Kolo Creek

LDShell Petroleum Development Company(SPDC) encountered two new gas sands at depth deeper than ever drilled in the Kolo Creek field. The well is Kolo Creek (KC) 41.

The sands were reached after tough drilling conditions in severely pressured zones. Shell is using the Chinese built High Pressure, High Temperature rig Hilong-27, to drill for deep gas sands in eastern Nigeria. It encountered such deeper gas sands in Gbaran-26 earlier in the year.
In Kolo Creek 40, Shell drilled through a previously discovered gas zone, which it found to be better developed in the well.

It did not encounter any new gas sand. In Kolo Creek 41, however, it drilled deeper, taking care of pore pressure and mud system issues, to arrive at two deeper gas sands. Sources at the department of petroleum resources (DPR), the country’s regulatory agency, would not disclose the depth of the new finds.


Italian Explorer Hits A New Pay Dirt In The Congo

ENI made a new discovery of gas and condensates offshore Congo, in the exploration prospect of Nkala Marine, located in Marine XII block, about 20 kilometers from the coast and 3 kilometers from the Nene Marine field, already in production.

The finding, realized through the Nkala Marine 1 well, is expected to have a potential of 250-350million barrels of oil equivalent in place.

West Africa Is Seadrill’s Crown Jewel

 ‘Nothing To Do With Elumelu’

Seadrill has nine rigs in contract in the waters off the coast of West Africa, the highest number in any single region.  It is 18% of the company’s total fleet of 50.

South east Asia comes next with eight rigs deployed, while the North Sea, which is offshore Norway and UK, are utilizing seven Seadrill rigs. TSaudi Arabia and Kuwait, which represent the entire middle east, host six Seadrill rigs. The UK based company has 15 rigs under construction.

Most of the Seadrill rigs in the West African waters are drillships (six), and they are almost all in Angola (3) and Nigeria (4).

West Polaris is in action for ExxonMobil in the Kizombo Satellite development in Angola’s prolific Block 15. TOTAL is using the West Gemini to drill wells in that country’s Block 17. The Jack UpWest Tucana works for Chevron in the shallow water Block O.

In Nigeria, TOTAL is using  the drillship West Jupiter for Egina development; the deepwater field is expected to come onstream in 2017 and expected to ramp up to 200,000BOPD. ExxonMobil, again, has two Seadrill drillships offshore Nigeria. West Capella is drilling Usan, while West Saturn is drilling Erha; the contracts are on until April 2017 and December 2016 respectively.

Subscribers to Africa Oil+Gas Report have enquired whether Seadrill’s ‘fortune’ in Nigeria has to do with the influence of the chairman of its local subsidiary, the business Tycoon Tony Elumelu. Our investigations indicate the contrary.  ExxonMobil’s deployment of four Seadrill rigs in the two largest oil producers in Africa is a result of the company’s “global understanding” with Seadrill in Houston, the global headquarters of the hydrocarbon industry.

The deepwater market will be tighter in Nigeria in the coming years; now that the second phases of the big fields: Bonga, Erha and Agbami are being drilled out. The next developments: Bonga South West Aparo (BSWAP), Ugie and Etan- Zabazaba, are smaller fields, which will be drained without requirements of long tenures for rigs.

TPDC Acquires Gradiometry Data Over the East African Rift

Tanzanian Petroleum Development Corporation (TPDC) has awarded CGG a contract to acquire high-resolution gravity gradiometry and aeromagnetic data over two onshore areas along the South-Eastern Tanzanian Coastal Basin and the eastern arm of the East African Rift.

“Acquisition over a total area of 30,000 sq km will commence in mid-August 2015 and is scheduled to last up to two months”, CGG announces in a release. “Using the industry’s lowest noise Gravity Gradiometry, FALCON®, CGG will deliver high-resolution data and interpretation to help evaluate the hydrocarbon potential of these basins ahead of future licensing rounds”.
