Tethys advances well tests in Kazakhstan

Tethys Petroleum Ltd. has completed testing the Klymene exploration well, KBD-02, in the Kul-Bas block, Kazakhstan (OGJ Online, Mar. 19, 2020). The well has produced 20,000 bbl of oil to date and has averaged over 400 b/d for the last week on a 9-mm choke with good oil quality and no water cut. The test to date has focused on the Jurassic zone as the widest of three potential zones. The current plan is to test this zone until July 7, followed by testing of the next zone. At present, the service provider is under quarantine but expected to be on location by July.

Tethys plans to drill 3 more gas wells later this year, assuming relaxation of quarantine restrictions.

Kul‐Bas block is a large exploration area of about 7,632 sq km northwest of the Aral Sea. A wildcat well was previously drilled into the Jurassic zone and Permo-Carboniferous limestones. Klymene prospect estimated gross unrisked mean prospective recoverable oil is about 422 million bbl.
