The companies found oil by drilling the Krabdagu-1 (KBD-1) exploration well, in the central area of Block 58.
The current drilling success follows previous discoveries made at the Maka, Sapakara, Kwaskwasi, and Keskesi wells, and the successful test at the Sapakara South-1 appraisal well.
Drilled to an approximate depth of 5,273m, using the Maersk Valiant rig, the Krabdagu-1 well encountered net oil pay of nearly 90m in good quality Campanian and Maastrichtian reservoirs.
The well is located 18km south-east of the Sapakara South appraisal well.
TotalEnergies exploration senior vice-president Kevin McLachlan said: “This successful exploration well at Krabdagu-1 is a significant addition to the discovered resources in the central area of block 58.
“This result encourages us to continue our exploration and appraisal strategy of this prolific block 58, in order to identify sufficient resources by year-end 2022 for a first oil development.”
APA Exploration senior vice-president Tracey Henderson said: “We are very pleased with the Krabdagu exploration well, which confirms our geologic and geophysical models, and de-risks additional prospects we have matured in the area.”
The partners plan to continue drilling and logging operations using the Maersk Valiant drillship.
The partners also plan to undertake drill stem test (DST) operations on the Krabdagu-1 well to appraise the resources and productivity of the two primary reservoirs.
This year, TotalEnergies and APA plan to drill at least three further exploration and appraisal wells in Block 58.
TotalEnergies operates the block with a 50% interest while APA Suriname holds the remaining 50% stake.
TotalEnergies recently agreed to sell minority stakes in several gas fields, located offshore the UK, to Kistos Energy.
