– Tethys Petroleum Ltd. reported encouraging reservoir parameters at its AKD01 (Doris) oil discovery on the Akkulka block in the Ustyurt basin in Kazakhstan and plans at least two appraisal wells.

The Cretaceous sandstone at 7,126-52 ft has permeability in excess of 1.7 Darcies and a large investigated distance of more than 6.25 miles and a connected volume of 29 million stb in place. The dolomite zone at 7,724-64 ft has 700 md permeability, and consulting engineers interpreted the existence of a similar zone in a previously drilled well more than 10 miles west.

Tethys has chosen the first appraisal well location and plans to shoot 3D seismic over the discovery and shoot targeted 2D seismic lines to firm up other potential in the area. The company has identified several other prospects that appear similar to Doris.

Tethys is moving the rig to a prospect called Daphne in a similar structural position 31 miles northwest to spud in late April targeting Cretaceous, Jurassic, Triassic, and Permo-Carboniferous intervals.
