APA Corporation has announced the successful drilling and flow testing of the Sapakara South-2 (SPS-2) appraisal well, the second appraisal well to test the previously announced discovery. The well is located approximately 4.6 kilometers (3 miles) south of the Sapakara South-1 (SPS-1) appraisal well.

SPS-2 encountered approximately 36 meters (118 feet) of net oil pay in high-quality Campano-Maastrichtian reservoir. Data collected from the flow test and subsequent pressure build-up indicated incremental connected resource of more than 200 million barrels (MMbbls) of oil in place.

“Results from the SPS-2 drilling and flow tests are consistent with our pre-drill expectations, confirm our geologic, geophysical, and reservoir models, and, importantly, add substantial resources towards a potential development,” said John J. Christmann IV, APA’s CEO and president.

Rig activity is ongoing and focused on drilling two appraisal wells at the Krabdagu discovery, which is located approximately 17 kilometers (11 miles) east of Sapakara. Krabdagu-2 is currently drilling; APA anticipates Krabdagu-3 will spud in February with a second drilling rig.

APA Suriname holds a 50% working interest in Block 58; TotalEnergies is the operator and holds the remaining 50% working interest.

Apache entered Suriname after winning bids for Block 53 and Block 58 offshore in 2012 and 2015, respectively.

The company expanded its understanding of the basin through extensive geologic modeling and seismic acquisition. In 2019, Apache began drilling the Maka Central-1 well in Block 58 and subsequently brought in TotalEnergies as a 50-50 Joint Venture partner to explore and develop the block. The partners have announced several discoveries beginning with Maka Central-1 in January 2020.
