Karachi: Pakistan Petroleum Limited (PPL) has successfully increased gas production from its Shahdad X-1 well in the Gambat South Block, Sindh. This significant achievement was made possible through an innovative water shut-off operation, marking a first for the Gambat South Block, as well as the introduction of acid-soluble cement technology—a first for PPL.
Following the operation, the gas flow rate from Shahdad X-1 has surged from 2.2 MMscfd to 8.4 MMscfd, an increase of over 280%. In addition, water production has been dramatically reduced, from 3,000 bbl/d to a mere 26 bbl/d, demonstrating PPL’s expertise in optimizing well performance and resource recovery.
Originally drilled in 2012 and brought into production in 2015, Shahdad X-1 was initially producing 26 MMscfd of gas. However, by 2024, the well experienced a significant decline in production due to an increase in water production, caused by inter-layer crossflow. To address this issue, PPL commissioned a Production Logging Tool (PLT) survey in August 2024, which confirmed the need for remedial action.
In response, PPL worked with a coiled tubing service provider to deploy the acid-soluble cement technology, effectively isolating the water-producing zones and restoring optimal gas flow. This successful operation underscores PPL’s technical innovation, operational excellence, and commitment to enhancing production from its mature fields. The company continues to focus on leveraging advanced technologies to maximise the potential of its assets, contributing to Pakistan’s energy security.”
