Pakistan Petroleum Limited (PPL), the operator of Gambat South Block, on Friday announced another gas discovery at its exploration well, Hadi X-1A, located in District Sanghar, Sindh.
Earlier, the company announced gas discovery in its first exploration well Kotri X-1 located in District Hyderabad, Sindh in May 2015.
PPL is working on this well with 65 per cent working interest along with its joint venture partners, Government Holdings Private Limited and Asia Resources Oil Limited with 25 per cent and 10 per cent working interest.
Hadi X-1A was spud on February 5 of this year and reached the final depth of 4,020 meters on April 19, 2016, the company announced. Based on wireline logs interpretation, potential hydrocarbon bearing zones were identified in Sembar Formation. During initial testing in Sembar Formation immeasurable amount of gas flowed at the surface for three days and reservoir appeared to be tight.
To further evaluate tight gas potential, Frac job was conducted after which flow rates improved significantly, the company said. The well flowed at 0.85 MMSCFD at 32/64 inches choke size, thus confirming the presence of natural gas at Hadi X-1A, it added.
Post Frac results suggest that it is a tight gas discovery. However, further evaluation is required to determine the size and commercial value of the discovery, based on post well studies and its integration with geological, geophysical and engineering data collected during drilling and testing of the well.
A pioneer of the natural gas industry in the country, PPL has been a frontline player in the energy sector since the mid-1950s. As a major supplier of natural gas, PPL today contributes over 20 per cent of the country’s total natural gas supplies besides producing crude oil, natural gas and liquefied petroleum gas in the country.
