ShaMaran Petroleum has updated on the operations at the Pulkhana-9ST2 geological sidetrack.
The original hole at Pulkhana-9 attained a total depth (TD) of 2333 m in the Cretaceous Balambo structure. A detailed testing campaign of six well tests (DST) retrieved oil from the four individual reservoir intervals, which contained two fresh reservoirs.
The company decided to sidetrack the well that focuses on the two lower zones, namely Balambo and Shiranish structures, with open hole barefoot testing, because of the lack of ability to receive sustained flow rates.
ShaMaran sidetracked the well. During the drill program, both the Balambo and Shiranish fractures offered considerable gas peaks with recovered oil from the surface. Under the analysis, both the structures flowed 30° to 33° API oil as limited quantities to the surface, though the Shiranish zone were examined at the oil rates of 600 to 2450 barrels per day from the early wells drilled in the field.
Currently, the drilling rig will hang the well and will be mobilized to the Pulkhana-10 well that will assess the fresh Jaddala oil reservoir and the proven Euphrates reservoir.
The company has a 60% of working interest in the Pulkhana Block and has become the operator of the Pulkhana-9 well.
