       Keskesi South-1 well at Block 58

       contains no commercial reserves

                         TOTALENERGIES of France and its US-based   Block 58 covers an area of about 1.4mn acres
                         partner APA have found hydrocarbons in Kesk-  (5,670 square km) within Suriname’s offshore
                         esi South-1, an appraisal well drilled in the east-  zone. TotalEnergies and APA have already made

                         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)
