As part of its 2025-26 programme in Gabon, VAALCO Energy is looking to deploy Borr Jack-Up XIV Inc for the drilling of multiple development wells and appraisal/exploration wells

Secured by a contract signed with Borr Drilling Limited, the rig will also be utilised for workovers, including the scope of drilling additional wells. Borr's Norve rig already operational at Panoro Energy's Dussafu Marin Permit for workover and ESP replacement activities will help boost gross production to 40,000 bopd by year end.

Optimisation plans

George Maxwell, Vaalco’s CEO said, "We are excited about the major projects planned for 2025 that are expected to deliver a step-change in organic growth across our portfolio in the coming years. In Gabon, we continue to work with our joint owners at Etame on our shared goal of executing another successful drilling campaign designed to enhance production and add reserves. We have signed a contract with Borr that we believe allows us the flexibility to optimise our drilling and workover plans offshore Gabon.

“We anticipate the programme to begin in mid-2025 with the sequencing and exact number of wells yet to be finalised. We are planning on multiple wells in the Etame field, multiple wells at our SEENT platform and a redrill and several workovers in the Ebouri field to access production and reserves that were previously shut in and removed from proved reserves due to H2S. Over the past three years, we have delivered on our focused strategy and believe we will continue to do so with the organic growth programmes across our diversified portfolio over the coming years.” 

Vaalco had reported strong progress for 2024.

The Norve jack-up rig is gearing up for action in West Africa as Borr Drilling Limited announced a new, US$58mn contract with a returning customer

Anticipated to take around 320 days, the contract scope includes five wells firm, with an additional five optional wells at mutually agreed prices.

Currently operating for Marathon Oil

The contract is expected to start in Q3 2025, following the completion of the premium rig's current operations for Marathon Oil. 

Marathon Oil's operations, which are in line with the government's Gas Mega Hub initiative in Equatorial Guinea, is also supported by Petrofac under a master service agreement.

The Afina discovery offshore Ghana confirmed good reservoir productivity from Cenomanian sandstones, and the presence of gas/condensate from Turonian reservoir

The results followed an appraisal well test activity by re-entry, as reported by Ghanaian company Springfield Exploration and Production Limited and its partners, Ghana National Petroleum Corporation (GNPC) and GNPC EXPLORCO. 

A drill stem test (DST) on the Cenomanian sandstone gave way to a maximum flow rate of 4500 barrels of oil per day confirming good reservoir productivity on the upper end of pre-test expectations, while indicating an estimated flow rate potential of up to 12,000 boepd from a mini-DST conducted on the Turonian sandstone.

Pressure transient analysis from this reservoir showed the pressures consistent with that collected in 2019, when the 1030m-deep Afina-1x was drilled to a total water depth of 4085 metres. 

Northern Ocean Limited-operated Deepsea Bollsta rig that was deployed for the campaign has been released post work completion. 

Considering well completion options

“We are extremely happy with the results of the appraisal programme which has further confirmed our understanding of our geological, geophysical, reservoir models and demonstrated our operational capacity. Afina-1x is a vertical well, we are confident that a horizontal well or other well completion options that maximise reservoir exposure in the fields would deliver much higher production rates. This provides an incredible platform for reaffirming commercial development options for the Cenomanian and Turonian reservoirs," said Kevin Okyere, chief executive officer of Springfield.

Four new exploration blocks offshore Ivory Coast have been handed over to oil major Eni by the country's Ministry of Mines, Oil and Energy as per an acquisition agreement signed in Abidjan during SIREXE, the International Exhibition of Extractive and Energy Resources 

The agreement allows Eni an exploration period of nine years on the blocks CI-504, CI-526, CI-706 and CI-708. Covering a total area of about 5,720 sq kms with a water depth ranging between 1,000 and 3,500 m, these blocks add to the oil major's already-strong deepwater presence across the region, including in CI-101, CI-205, CI-401, CI-501, CI-801 and CI- 802. Of these, Baleine and Calao remain the company's biggest discoveries at a global scale. 

The partners have been in talks since early this year, when the President of Ivory Coast, Alassane Ouattara, and the CEO of Eni, Claudio Descalzi, met in Abidjan to discuss the company’s activities in the country, including the successful results of the exploration well Murene 1X on the Calao discovery. 

Boosting production 

Eni is increasingly focusing on boosting production from these sites, with the launch of Baleine Phase 2 set for this month, aiming to reach a total production count to 60,000 barrels of oil per day and 70 million cubic feet of associated gas (equivalent to 2 mn cu/m of associated gas). Once achieved, this will mark an increase to 150,000 bopd and 200 mn cu/ft of associated gas during Phase 3, currently under study. 

Interests in Ivory Coast sees growth, as Viridien announced in May two new multi-client 3D reimaging programmes from the region, CDI24 Phase I (3,120 sq km) and Phase II (6,610 sq km).
