plugged and abandoned, it said.
Tracey K. Henderson, APA’s senior vice-pres-
ident for exploration, indicated that the results
from the well had yielded valuable information
about the hydrocarbon reservoirs at Block 58.
“The first appraisal well at Keskesi was a sub-
stantial step-out designed to assess the southern
extent of the feature,” he said. “This location had
the potential to confirm a very large resource
in place if connected to the reservoir sands in
the discovery well. However, suitable reser-
voir-quality sands were not developed in the
Campanian target at the Keskesi South-1 loca-
tion. Data gathered from the well will be used
to calibrate our geologic model and inform the
next steps for Keskesi appraisal.”
Now that Keskesi South-1 has been com-
pleted, APA added, the Maersk Discoverer
drillship will move to the Sapakara South-1 well,
where it is due to conduct a flow test of a previ-
ously announced successful appraisal. Once it
wraps up the testing programme, it will move
closer to the eastern edge of Block 58 to spud a
new exploration well at the Krabdagoe prospect.
Meanwhile, the statement noted, another
drillship, the Maersk Valiant, is sinking the Bon-
boni-1 exploration well in the northern part of
the block. TotalEnergies and APA have not said
when they expect to finish this well. Keskesi South-1 is near the eastern edge of Block 58 (Image: Frontera Energy)
