Kazakhstan-focused upstream Jupiter Energy said Wednesday that its Well 19 discovered a hydrocarbon pay zone in onshore Kazakhstan.

The well, located in Block 31 just east of the Caspian Sea, reached a total depth of 10,065 feet.

“Hydrocarbon shows while drilling, mud logging, and subsequent open hole wireline logs all indicated hydrocarbons in the Mid Triassic reservoir,” Australia-based Jupiter said.

Analysis by local independent consulting firm Reservoir Evaluation Services confirmed a gross reservoir of 326 feet and a net pay of 277 feet at the well’s primary objective in the Middle Triassic T2B carbonate reservoir unit.

Analysis also confirmed an additional 50 feet of gross reservoir and 34 feet of net pay at the Middle Triassic T2A carbonate reservoir unit.

Jupiter has acquired open hole logs and production casing is now being run in preparation for a brief period of well testing.

“The open hole logs indicated good levels of oil saturation and porosity, similar to that of the J-51 and J-52 wells which were also drilled on the same structure,” Jupiter said.

Well 19, the company’s eighth well at its wholly owned Block 31, will be shut in after a brief well test until “domestic oil process make trial production operations economically viable.”
