Doris Oil Field
The AKD01 was the first deep exploration well drilled under the Akkulka Exploration Contract on the Akkulka block and has provided in excess of 4 MM bblsof oil.
Well AKD01 encountered two oil bearing zones, the lower zone being an Upper Jurassic carbonate sequence at approximately 2,355 metres and an upper, Lower Cretaceous sandstone zone at approximately 2,174 metres. Oil shows were also encountered in the Triassic sequence but not tested. Oil quality is very good in both zones, with the lower zone having 46 degree API low sulphur crude and the upper zone 37 degree API low sulphur crude.
The upper lower Cretaceous sandstone interval showed extremely good permeability (in excess of 1.0 Darcy) and a large investigated distance and therefore a large connected volume, that indicates a very high quality laterally extensive reservoir. The lower carbonate zone also showed good permeability with a large investigated distance and significant connected volume.
The Company is currently producing oil under a Pilot Production Contract and oil from the same Doris discovery horizons has tested successfully from wells AKD05 and 6 and there is a further discovery, Dione, in an Upper Jurassic sand in well AKD03.
There is very good potential exploration in the area. Further similar prospects have been mapped in the Akkulka and Kul-Bas block near to Doris and the appraisal programme on the Doris oil discovery, the Dione field south of Doris and further exploration on the Akkulka block is continuing.
