Pakistan’s Mari Energies Limited has announced a new gas discovery at an exploratory well in Balochistan, a development the company says could help strengthen the country’s domestic energy supply.
In a notice to the Pakistan Stock Exchange (PSX), Mari Energies said gas had been discovered at the Tibri-1 well, drilled in the Kalchas South Block in Dera Bugti district.
The Kalchas South Block is operated by United Energy Pakistan Limited (UEPL), which holds a 46% working interest in the joint venture. Mari Energies owns a 44% stake, while Dewan Petroleum Pvt Limited holds the remaining 10%.
Tibri-1 is the first exploratory well drilled in the Kalchas South Block. Drilling began on 11 November 2025 and reached a total depth of 7,170 feet, according to the company’s filing.
Initial testing of the Dunghan/Sui Main Limestone formation produced encouraging results. During testing, the well flowed gas at a rate of 11 million standard cubic feet per day at a 64/64-inch choke, with a wellhead flowing pressure of 561 pounds per square inch gauge. At a smaller 32/64-inch choke, gas flowed at 6.5 million standard cubic feet per day with a pressure of 1,161 psig.
Mari Energies said further testing is under way to determine the well’s full production potential.
The company noted that exploration activity in the area had remained dormant for a long period due to security concerns. Operations resumed after the joint venture acquired Dewan Petroleum’s working interest in July 2023, paving the way for renewed exploration and the drilling of Tibri-1.
Mari Energies said the discovery underscores the joint venture’s efforts to expand Pakistan’s indigenous hydrocarbon resources at a time when the country is seeking to reduce reliance on imported energy and improve energy security.
Pakistan has faced persistent gas shortages in recent years, particularly during winter months, prompting renewed focus on domestic exploration alongside imports of liquefied natural gas.
