The first exploratory well in the Zhambyl structure of the Kazakh sector of the Caspian Sea flowed oil and gas from the Middle Jurassic, two partners reported.
The ZB-1 well was drilled to 2,200 m from May to August. Tests resulted in a production volume of 24 cu m/day through a 6.35-mm choke from one zone and 110 cu m/day with a 12.7-mm choke from another.
KazMunayGas and partner Korean Consortium KC Kazakh BV reported the results. Operator of the well is Zhambyl Petroleum.
Exploration work will continue with 3D seismic studies in Zhambyl and drilling of exploratory well ZT-1 in the Zhetysu structure.
