Mari Energies announces gas discovery at Tibri-1 well in Balochistan

Mari Energies Limited has announced a gas discovery at the Tibri-1 exploratory well drilled in the Kalchas South Block in Dera Bugti district of Balochistan, according to a notice issued to the Pakistan Stock Exchange on Monday.

The company said Tibri-1 is the first exploratory well in the Kalchas South Block and was spudded on November 11, 2025, reaching a total depth of 7,170 feet.

The Kalchas South joint venture is operated by United Energy Pakistan Limited with a 46% working interest, while Mari Energies Limited holds 44% and Dewan Petroleum (Private) Limited holds the remaining 10%.

Initial testing of the Dunghan/Sui Main Limestone formation showed a gas flow rate of 11 million standard cubic feet per day at a 64/64-inch choke with a wellhead flowing pressure of 561 psig. At a 32/64-inch choke, the well flowed 6.5 MMSCFD with a wellhead flowing pressure of 1,161 psig. The company said further testing is in progress to assess the well’s full potential.

Mari Energies noted that exploration activity in the area had remained suspended for an extended period due to security challenges. The joint venture resumed operations after acquiring working interest from Dewan Petroleum in July 2023, leading to the Tibri-1 discovery.

The company said the discovery reflects the joint venture’s continued focus on developing Pakistan’s domestic hydrocarbon resources.
