According to operator Apache, the well successfully tested hydrocarbons from multiple stacked targets in the upper Cretaceous Campanian and Santonian intervals.

Fluid analysis and test results indicate at least 79 m (259 ft) of net oil and gas condensate pay within two intervals.

The shallower Campanian interval holds 13 m (43 ft) of net gas condensate and 30 m (98 ft) of net oil pay, with API gravities between 35 and 40°. The deeper Santonian interval contains 36 m (118 ft) of net oil-bearing reservoir with a 40-45°API range.

Apache has identified at least seven distinct play types and more than 50 prospects within the thermally mature play fairway across the block.

Upon completion of the current well, the Sam Croft will move 10 km (6 mi) to the northwest to drill the Kwaskwasi prospect.

A fourth exploration target Keskesi will then be drilled, located 20 km (12 mi) southeast of Sapakara West-1. Both these wells will test oil-prone upper Cretaceous targets in the Campanian and Santonian intervals in reservoirs that appear to be independent from Maka and Sapakara.
