Mari Petroleum announces gas discovery in North Waziristan

Mari Petroleum Company Limited (MARI) has reported a significant gas discovery at the Shewa-2 appraisal-cum-exploratory well in the North Waziristan district of Khyber Pakhtunkhwa Province, as disclosed in their filing on the Pakistan Stock Exchange (PSX).

The drilling of the well, which reached a depth of 4,577 meters on November 01, 2023, aimed to appraise the Lockhart and Hangu formations, previously identified in the exploratory well Shewa-1, and evaluate the hydrocarbon potential of the Samanasuk and Kawagarh formations.

A Drill Stem Test conducted in the Kawagarh formation, one of the exploratory targets, yielded a sustainable gas flow rate of 0.607 million standard cubic feet per day (MMSCFD) at a wellhead flowing pressure (WHFP) of 97 pounds per square inch (Psi) using a 32/64-inch choke size.

This discovery in the Kawagarh formation complements the previously identified hydrocarbon-bearing reservoirs in the Lockhart and Hangu formations at Shewa-1.

The appraisal of the Lockhart and Hangu Formations at Shewa-2 has verified the extension of the hydrocarbon reserves in these formations. 

The Hungu formation at the same well recorded a gas flow rate of 0.274 MMSCFD at a WHFP of 77 Psi, also using a 32/64-inch choke size.

Furthermore, post-acid treatment, the Lockhart formation at Shewa-2 well demonstrated a gas flow rate of 51 MMSCFD and 391 barrels of condensate per day at a WHFP of 5,972 Psi, employing a 38/64-inch choke size.

Mari Petroleum holds a 55% working interest and operates the Waziristan Block, with joint venture partners OGDCL and OPI having working interests of 35% and 10%, respectively, as it is told in its filing on PSX.
