APA Corporation (Nasdaq: APA) and Total S.A. (NYSE: TOT) today updated the operational status of the Keskesi East-1 discovery well offshore Suriname.

As announced on Jan. 14, 2021, Keskesi East-1 discovered oil, volatile oil and condensate in the Upper Cretaceous-aged Campanian and Santonian intervals and, subsequently, continued drilling toward deeper Neocomian-aged targets. As drilling progressed, the well encountered substantial pressure increases that APA and Total determined could ultimately exceed the capabilities of the wellbore design and pressure control equipment. Consequently, the partners decided to conclude drilling operations at Keskesi before reaching the Neocomian targets. Information gathered from this well will be used to design a wellbore and drilling program that will ensure a safe test of the deep Neocomian targets in future exploration and/or appraisal operations.

The additional drilling at the Keskesi East-1 well encountered hydrocarbons in the Lower Cretaceous interval and a carbonate depositional system above the top Neocomian target, both of which help to validate the partners’ geologic models. While encouraging, this data does not reveal specific information about the Neocomian targets themselves.

With the completion of operations at Keskesi East-1, the Noble Sam Croft drillship will be released as planned.

Pursuant to the terms of its joint venture agreement, APA transferred operatorship of Block 58 to Total S.A. on Jan. 1, 2021. APA holds a 50% working interest in Block 58 and Total holds the remaining 50% working interest.
