Key Caspian discovery at Kalamkas by Agip-led consortium
The Parker Rig 257.
(10/10/2002 - OGI: Paris) Another significant discovery has been made in the northern sector of the Caspian Sea on the Kalamkas structure by the Agip-led North Caspian Sea Consortium, holders of the Kazakhstan production sharing agreement for the giant Kashagan exploration area some 85 km northeast of the discovery site. TotalFinaElf, one of the members of the group, reported today that the Kalamkas-1 exploratory well, drilled by the Parker Rig 257 in 15 ft water depth, encountered several hydrocarbon reservoirs in the Jurassic section downward from 5,305 ft (1,617 meters) to the total depth at 7,743 ft (2,360 meters).
TotalFinaElf said the discovery well, which was spudded in mid-April, was the first to be drilled on the Kalamkas structure, another large formation that extends across portions of five Kazakh blocks, Blocks 1, 4b, 5a, 6a, and 8a. The well tests indicated an initial flow rate of 2,300 b/d of oil on a 32/64-inch choke.
Located offshore the Atyrau Oblast coast of Kazakhstan, the Kalamkas blocks are part of a group of blocks attributed to the North Caspian Sea Consortium that includes the giant Kashagan Field.
The contracting companies involved in the North Caspian Sea PSA are: Eni, the operator with 16.67% interest, BG (16.67%) ExxonMobil (16.67%), Inpex (8.33%), Phillips (8.33%), Shell (16.67%), and TotalFinaElf (16.67%).
