KrisEnergy says the estimated ultimate recovery from the five development wells in the Apsara oil development is “likely to be a small fraction” of the pre-development estimates due to significantly lower volume of hydrocarbon-in-place connected to the wells.

The underperformance is also attributed to the geographical complexity resulting in smaller oil accumulations.

Additional contributing factors include pressure depletion being the dominant recovery mechanism with little to no evidence of water support, resulting in a lower recovery factor, as well as lower-than-anticipated well productivity that may be due to potential formation damage in the oil-bearing zones.
