PPL’s Gambat South well yields possible tight gas discovery

The Pakistan Petroleum Ltd.-operated Hadi X-1A exploration well, located on the Gambat South block in the Sanghar district of Pakistan’s Sindh province, flowed 0.85 MMscfd on a 32/64-in. choke, confirming the presence of natural gas.

The Pakistan Petroleum Ltd.-operated Hadi X-1A exploration well, located on the Gambat South block in the Sanghar district of Pakistan’s Sindh province, flowed 0.85 MMscfd on a 32/64-in. choke, confirming the presence of natural gas.

Hadi X-1A was spudded on Feb. 5, and reached the final depth of 4,020 m on Apr. 19. Based on wireline logs interpretation, potential hydrocarbon bearing zones were identified in the Sembar formation.

During initial testing in Sembar, gas flowed at the surface for 3 days and the reservoir appeared to be tight, PPL says. To further evaluate the tight gas potential, a frac job was conducted after which flow rates improved significantly.

Post-frac results suggest a tight gas discovery. However, PPL says further evaluation is needed to determine its size and commerciality based on post-well studies and integration with geological, geophysical, and engineering data collected during drilling and testing of the well.

PPL holds 65% interest in Gambat South alongside joint venture partners Government Holdings Private Ltd. 25% and Asia Resources Oil Ltd. 10%.

PPL in May reported the Kotri X-1 well on the Kotri block of the Hyderabad district in Sindh province flowed gas at 3.4 MMcfd with a wellhead pressure of 608 psi (OGJ Online, May 24, 2016).
