Islamabad: Pakistan Petroleum Limited (PPL) has reported on its discovery of hydrocarbon reserves in its first exploratory well Margand X-1 – situated in the Kalat District of Balochistan, a news source reported.
After the results of wireline logs, Modular Dynamics Testing (MDT) was employed, which proved the presence of hydrocarbon. Consequently, drilling at Margand X-1 began on June 30 last year and was done to the depth of 4,500 metres inside Chiltan limestone.
Drill Stem Test (DST) showed ‘a flow of 10.7 million cubic feet of gas per day (mmcfd) at 64/64 inches choke size with flowing wellhead pressure at 516 pounds per square inch (psi) and 132 barrels of liquid per day’.
According to conjectures, the reservoir might have a potential deposit of one trillion cubic feet; however, PPL has not announced the actual size of the hydrocarbon potential. A PPL official said that the estimate of hydrocarbon reserve could not be guessed until the drilling reached the targeted depth and more tests were conducted.
