U.S. independent E&P firm Apache Corp. has commenced exploration on a new location in Block 58 offshore Suriname, Kallanish Energy reports.
Having already made three oil and oil/gas condensate discoveries in wells throughout the Block earlier this year, Apache confirmed that drilling operations at the Keskesi East-1 well has commenced last week.
In a statement, Apache stated that the exploration well, approximately 14 kilometers (9 miles) southeast of Sapakara West-1, will test upper Cretaceous targets in the Campanian and Santonian.
Apache holds a 50% working interest in Block 58 and will continue to be the operator through the completion of the Keskesi well. Total S.A. holds the remaining 50% working interest.
Discoveries in Block 58 at the Kwaskwasi-1 well was announced in late July, following those in January and April this year of discoveries at the Maka Central-1 and Sapakara West-1 wells.
Apache stated that the Kwaskwasi-1 well was drilled to a depth of approximately 6,645 meters (21,800 feet) and successfully tested for the presence of hydrocarbons in multiple stacked targets. Test results found at least 278 meters (912 feet) of net oil and volatile oil/gas condensate pay in two intervals.
According to the company, the shallower Campanian interval contains 63 meters (207 feet) of net oil pay and 86 meters (282 feet) of net volatile oil/gas condensate pay, while the Santonian interval contains 129 meters (423 feet) of net pay.
Apache was unable to collect representative fluid samples from the reservoir due to conditions caused by “cementing operations, which were required to mitigate increased pressure below the base of the Santonian formation.”
“Hydrocarbon shows were observed in the Santonian reservoirs, and the results of the formation evaluation indicate the presence of oil.”
