HOUSTON, Apr. 2 -- Tethys Petroleum Ltd., Guernsey, Channel Islands, UK, gauged an apparent Cretaceous deeper pool gas discovery on the Akkulka Block in Kazakhstan's North Ustyurt basin.
The AKK-14 exploration well, drilled on a prospect between the AKK-13 and AKK-04 discoveries, flowed a combined 13.3 MMcfd of gas from two intervals. The company's highest-rate test on the block, it appears to be the first commercial discovery in Cretaceous Tasaran sand.
The Tasaran sand stabilized at 7.5 MMcfd with 163 psig flowing tubinghead pressure on a 30-mm choke, while the overlying Paleocene Kyzyloi sand stabilized at 5.8 MMcfd with 152 psig flowing tubinghead pressure on the same size choke.
The Tasaran is made up of several units of up to 20 ft of blocky, medium-grained sandstones and are more conventional reservoirs than the generally thinner and finer-grained Kyzyloi sandstone, the company said.
The company plans to examine existing seismic for potential untested Tasaran zones in several older wells and for new leads. The discovery opens a new play on both the Akkulka and Kul-Bas blocks.
