TotalEnergies has advanced exploration activity on Block 58 offshore Suriname with data from the Krabdagu flow test that accelerates the company’s understanding of the field and will shape future activity, partner APA Corp., Houston, said in a release June 21.
Results
Flow test data from the two lower intervals—the Upper Campanian and Lower Campanian—of the Krabdagu exploration well (KBD-1) indicate oil-in-place resource of about 100 million bbl and 80 million bbl, respectively (OGJ Online, Feb. 21, 2022).
In the Upper Campanian zone, the company encountered 32 m (105 ft) of net oil pay, high quality reservoir with 400-500 millidarcy permeability, 35-degree API, and 2,000-2,300 scf/bbl GOR.
In the Lower Campanian zone, the joint venture encountered 32 m (105 ft) of net oil pay, modest reservoir quality with 60-80 millidarcy permeability, 37-degree API, and 2,500-2,800 scf/bbl GOR.
Future activity
The tests were performed in the exploration well, and appraisal drilling will be necessary to confirm additional resource and optimal development well locations, APA said in the release. The exploration well encountered another high quality, lower GOR interval in the Upper Campanian that was not in a location suitable for flow testing. The company said this shallower Campanian zone will need to be flow tested in the appraisal stage from a more optimal location.
Results from the flow-test in the two lower intervals are in line with expectations and provide data for future activity including identifying optimal well locations “that enable assessment of upside resource potential for each target,” said John J. Christmann IV, APA chief executive officer and president. “The connected resource demonstrated from the flow tests at Krabdagu combined with the results from Sapakara South, are a significant step forward in advancing a project in this area of Block 58.”
The TotalEnergies-APA joint venture is currently drilling the Dikkop exploration well in the central portion of Block 58 with the Maersk Valiant drillship. Following completion of operations, the drilling rig is expected to continue exploration and appraisal activities in the central portion of Block 58 (OGJ Online, June 16, 2022).
TotalEnergies is operator of the block with 50% interest. APA Suriname holds the other 50%.
