Mari Energies Limited (PSX: MARI) has announced a commercial oil and gas discovery at its Mari Ghazij CF-B1 exploration well in the Mari Development & Production Lease (D&PL) area of Sindh, the company said in a material disclosure filed with the Pakistan Stock Exchange. Pakistan Stock Exchange+1
The well was spud-in on September 12, 2025 and was successfully drilled to a total depth of 1,195 metres, reaching the Sui Upper Limestone (SUL) and targeting oil-prone intervals within the Ghazij formation, the PSX disclosure states. Pakistan Stock Exchange
During testing, the company reported preliminary flow figures from the exploratory interval: ~305 barrels per day (bpd) of oil together with ~3 million standard cubic feet per day (MMSCFD) of gas, with a reported wellhead flowing pressure (WHFP) of 225 psi at a 48/64″ choke size. These rates are initial and will be subject to further appraisal and longer-term testing before final reserves and development plans are confirmed. Profit by Pakistan Today+1
Mari Energies holds a 100% working interest and is the operator of the Mari D&PL; this discovery therefore sits squarely within the company’s operated onshore portfolio. The company disclosed the find under Section 96 of the Securities Act, 2015, which requires timely public disclosure of material information that could influence investor decisions.

Why this discovery matters
For Mari Energies, the Mari Ghazij CF-B1 result strengthens its onshore asset base and creates near-term optionality for appraisal drilling, reservoir evaluation and potential tie-in to existing infrastructure in the Mari D&PL. For Pakistan, incremental local production from onshore discoveries can help ease import pressures and support energy security if commerciality is confirmed. Ground News+1
What comes next
The company will likely proceed with an appraisal programme to delineate the discovery, quantify recoverable volumes, and test adjacent Ghazij intervals. Subsequent steps include reservoir evaluation, possible partner / offtake discussions and submission of a field development plan if appraisal confirms commercial viability. Market participants will watch PSX filings for test updates and development timelines. Pakistan Stock Exchange+1
