KARACHI: The Pakistan Petroleum Limited (PPL), the operator of Gambat South Block with 65 percent working interest (WI), along with its joint venture partners – the Government Holdings Private Limited and Asia Resources Oil Limited with 25 percent and 10 percent WI, respectively – has announced a gas discovery at its exploration well Zafir X-1 located in Sanghar district of Sindh. Zafir X-1 was spud on March 14 and the final depth of 3,928 metres was reached on April 12. Based on the wire-line logs, potential hydrocarbon bearing zones were identified, which are under testing. Initial testing in massive sand of Lower Goru Formation flowed 29.2 mmscfd (million standard cubic feet per day) of gas, and 310 bbls/day of condensate at 48/64 inches choke, thus confirming the presence of commercial quantities of hydrocarbons at Zafir X-1. The well is being flowed at different choke sizes to measure gas flow rates, and the actual flow potential of the well will be determined after completion of the test.
