Mari Petroleum Company Limited (MARI), a major player in natural gas production, has announced a significant gas discovery at the Shewa-2 well located in the North Waziristan district of Khyber Pakhtunkhwa. The company shared this development in a notice to the Pakistan Stock Exchange (PSX) on Thursday.
According to the notice, MARI is the operator of the Waziristan Block, holding a 55% working interest, with joint venture partners OGDCL and OPI having 35% and 10% working interest, respectively.
The Shewa-2 well, drilled to a depth of 4,577 meters on November 01, 2023, aimed to appraise the Lockhart and Hangu formations, previously discovered at the Shewa-1 exploratory well. Additionally, the well tested the hydrocarbon potential of exploratory targets, namely the Samanasuk and Kawagarh formations.
The Drill Stem Test (DST) in the Kawagarh formation revealed 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) with a 32/64-inch choke size.
The discovery in the Kawagarh formation supplements the earlier finds in the Lockhart and Hangu formations at the Shewa-1 well. The appraisal of the Lockhart and Hangu formations confirmed the extension of the hydrocarbon play in these formations. The Hungu formation, part of Shewa-2, was tested at a gas flow rate of 0.274 MMSCFD at WHFP of 77 Psi at a 32/64-inch choke size.
Furthermore, the Lockhart formation in Shewa-2, tested post-acid, exhibited a gas flow rate of 51 MMSCFD and 391 barrels of condensate per day at WHFP of 5,972 Psi at a 38/64-inch choke size.

The company plays a vital role in the oil and gas exploration and production sector, serving key customers such as fertilizer manufacturers, power generation companies, gas distribution entities, and refineries.
