Mari Energies Limited (PSX: MARI) has announced a gas discovery at the Tibri-1 exploratory well drilled in the Kalchas South Block, located in Dera Bugti District, Balochistan.

The Kalchas South Block is operated by United Energy Pakistan Limited (UEPL), which holds a 46% working interest. Mari Energies owns a 44% stake in the joint venture, while Dewan Petroleum (Pvt.) Limited (DPL) holds the remaining 10%.

Tibri-1 is the first exploratory well drilled in the block. Spudding commenced on November 11, 2025, and the well was drilled to a total depth of 7,170 feet.

Initial testing of the Dunghan/Sui Main Limestone (SML) formation delivered encouraging results, with gas flowing at a rate of 11 million standard cubic feet per day (MMSCFD) at a 64/64-inch choke and a wellhead flowing pressure of 561 psig. Additional testing recorded a flow rate of 6.5 MMSCFD at a 32/64-inch choke with a higher wellhead pressure of 1,161 psig.

The company noted that further testing is currently underway to evaluate the full production potential of the well.

Exploration activity in the area had remained limited for several years due to security-related challenges. However, following Mari Energies’ acquisition of DPL’s working interest in July 2023, exploration efforts resumed, ultimately leading to the Tibri-1 discovery.

The latest find underscores the joint venture’s commitment to enhancing Pakistan’s domestic hydrocarbon supply and reviving exploration activity in previously underexplored regions.
