In an update to an evaluation of the Kwaskwasi-1 discovery well offshore Suriname, Apache and Total said the Noble Sam Croft drillship gathered reservoir and other technical data in the upper cretaceous-aged Santonian intervals since its 29 July discovery.

Rotary sidewall cores were retrieved, but representative fluid samples from the reservoir were not collected due to conditions caused by cementing operations, which were required to mitigate increased pressure below the base of the Santonian formation. Hydrocarbon shows were also observed in the Santonian reservoirs, and the results of the formation evaluation indicate the presence of oil.

The shallower Campanian interval contains 63 m (207 ft) of net oil pay and 86 m (282 ft) of net volatile oil/gas condensate pay. The Santonian interval contains 129 m (423 ft) of net pay. Fluid samples from the Campanian validated the presence of oil with 30–43 °API.

The drillship also began operations at the Keskesi East-1 exploration well, which will test upper Cretaceous targets in the Campanian and Santonian, approximately 14 km (9 miles) southeast of Sapakara West-1.

Apache holds a 50% working interest in Block 58 and is the operator through completion of the Keskesi well. Total holds the remaining 50% working interest.
