Petronas subsidiary PC Gabon Upstream (PCGUSA) has awarded a contract to Maersk Drilling to provide deepwater drillship rig for one-well drilling work offshore Gabon.

The Maersk Drilling’s Maersk Viking drillship will be used by Petronas to drill an ultra-deepwater exploration well located at approximately 2,100m water depth in Block F13 offshore Gabon.

Work under the contract is planned to commence in the third quarter of 2021. The contract, which is valued at approximately $24m, also includes mobilisation and demobilisation fees.

Maersk Drilling COO Morten Kelstrup said: “We’re delighted to expand our international relationship with Petronas, with whom we have worked on deepwater wells in the Far East, the Americas and now West Africa. We’re looking forward to conducting our first-ever campaign in Gabon.”

The Maersk Viking ultra-deepwater drillship is currently operating offshore Brunei Darussalam.

Upon completion of the contract with PCGUSA, the rig is planned to be moved to start work under the four-well contract signed earlier with Shell Malaysia.

In February, Korea National Oil Corporation (KNOC) awarded a $14.5m contract to Maersk Drilling for the drillship Maersk Viking to drill one exploration well in Block 6-1 offshore the Republic of Korea.

Work under this contract is scheduled to start in June.

In 2018, PCGUSA made oil and gas discovery from its Boudji-1 exploration well in Block F14 (Likuale), located in South Gabon.

Drilled in water depths of 2,800m, the ultra-deepwater exploration well encountered 90m of gross high-quality hydrocarbon-bearing pre-salt sands.
