HOUSTON, Aug. 3 -- Tub-Karagan Operating Co. BV abandoned the first exploration well on the Tub-Karagan Block in the Caspian Sea off Kazakhstan after drilling to the planned TD of 2,500 m.
The operator ran a full suite of geological and geophysical logs and ran geological and geochemical analyses of core samples, formation fluid samples, and drill cuttings.
"Based on the results of the studies, the well log did not demonstrate any oil and gas-bearing reservoirs and targets of commercial value," Tub-Karagan said.
The well, drilled from the Astra jack up in a zero-discharge operation, was to have evaluated Jurassic, Cretaceous, and Triassic sediments on the 1,372 sq km block (OGJ Online, Dec. 22, 2004).
Tub-Karagan Operating is a combine of KazMunaiTeniz and Lukoil Overseas, 50% each.
