The lower Cretaceous sand interval in this well appears however to be water bearing probably due to faulting between the two wells. Work is now underway on preparing for a flow test on the carbonate interval following which it is planned to sidetrack the AKD02 well to the south-east with the aim of encountering the upper reservoir potentially within the oil bearing zone.
Graham Wall, chief operating officer of Tethys, said: “The initial results of the AKD02 appear to show an oil bearing interval in the same carbonate sequence as flowed oil in the AKD01 discovery well. The cores through this interval show zones of vuggy and cavernous porosity as well as extensive fracturing and oil shows.”
The company said that it will now move ahead and test the carbonate zone, and then sidetrack the well towards AKD01 in order to encounter the upper reservoir the other side of the possible fault. It has already mobilized a seismic crew to the area to acquire a full 3D over this structure to increase our understanding. A preliminary swathe of these data will be used to assist in locating the sidetrack.
The company claims that these are initial results and that they may be subject to change and modification of the interpretation once the final results of the well have been obtained.
