ISLAMABAD: Mari Energies Limited on Monday announced a gas discovery at the Tibri-1 exploratory well in the Kalchas South Block, located in Dera Bugti district of Balochistan.
In a notice to the Pakistan Stock Exchange (PSX), the company said the Kalchas South joint venture is operated by United Energy Pakistan Limited (UEPL), which holds a 46 percent working interest. Mari Energies Limited owns a 44 percent working interest, while Dewan Petroleum (Pvt.) Limited holds the remaining 10 percent.
The Tibri-1 well is the first exploratory well drilled in the Kalchas South Block. Spudded on November 11, 2025, the well was drilled to a total depth of 7,170 feet.
According to the notice, initial testing of the Dunghan/Sui Main Limestone (SML) formation yielded promising results. The well flowed gas at a rate of 11 million standard cubic feet per day (MMSCFD) at a 64/64-inch choke with a wellhead flowing pressure of 561 psig. At a smaller 32/64-inch choke, it produced 6.5 MMSCFD of gas with a wellhead flowing pressure of 1,161 psig.
Mari Energies said further testing is under way to fully evaluate the reservoir’s potential. The company noted that exploration activity in the area had remained dormant for an extended period due to security challenges.
It added that following the acquisition of additional working interest from Dewan Petroleum in July 2023, the joint venture resumed exploration operations, leading to the Tibri-1 gas discovery and reaffirming its commitment to boosting Pakistan’s domestic hydrocarbon resources.
