ATTOCK – Pakistan Petroleum Limited (the ‘Company’), the operator of Dhok Sultan (Exploration Licence), has made an oil and gas discovery at its well “Dhok Sultan-03”, located in district Attock, Punjab province. This is the second discovery in the Dhok Sultan Block by the company as an operator holding 75 percent Working Interest (WI), alongwith its Joint Venture Partner, Government Holdings Private Limited (GHPL), which holds 25 percent WI. After rigorous internal geological and geophysical evaluation and deliberations, the well Dhok Sultan-03 was spudded on January 18, 2025 and drilled down to a depth of 5,815 metres MD BKB (Measured Depth Below Kelly Bushing) to test the hydrocarbon potential of the naturally fractured carbonates of Patala and Lockhart formations.
Potential hydrocarbon bearing zones were identified in the said reservoirs based on the drilling results and acquired wireline logs interpretations. During testing, the well flowed 1,469 barrels per day of oil and 2.56 MMscfd of gas at Wellhead Flowing Pressure (WHFP) of 1,147 psig on a 32/64” choke, and 2,113 barrels per day of oil and 4.13 MMscfd of gas at WHFP of 813 psig on a 48/64” choke. This achievement highlights the substantial untapped hydrocarbon potential of the mature Potwar–Kohat sub-basin, which can be effectively unlocked through the deployment of advance technologies in prospect evaluation and well drilling. In addition, this discovery will add additional hydrocarbon reserves and will save significant foreign exchange for the country through indigenous hydrocarbon production. It is worth mentioning that Dhok Sultan area is located almost 125-km away from district headquarters.
