Karachi, January 23, 2025 – Pakistan Petroleum Limited (PPL) has announced a remarkable increase in gas production at the Shandad X-1 well, located in the Gambat South Block.
In a statement submitted to the Pakistan Stock Exchange (PSX), PPL revealed the successful implementation of a water shut-off operation at the site. According to the company, this breakthrough intervention has significantly boosted gas production from 2.2 million standard cubic feet per day (MMscfd) to 8.4 MMscfd. Additionally, water production has been drastically reduced from 3,000 barrels per day (BPD) to a mere 26 BPD, marking a major operational success.
Shandad X-1, a sweet gas well initially drilled in 2012, became operational in 2015 with an initial production rate of 26 MMscfd. However, by 2024, output had sharply declined due to excessive water production. A Production Logging Tool (PLT) survey conducted in August 2024 confirmed inter-layer crossflow as the primary issue, necessitating effective remedial action.
To address this, PPL collaborated with a coiled tubing service provider to design a precise and innovative solution. After careful consideration of cost, risk, and operational feasibility, the team opted for an acid-soluble cement to isolate the water-producing zones. The operation faced initial challenges, including fluid losses during well-kill procedures, which were mitigated using Loss Circulation Material (LCM) and brine to stabilize the well. Cement placement was then successfully executed, followed by a 32-hour curing period, with results validated through slickline confirmation.
This achievement marks a significant milestone for PPL, as it is the first successful water shut-off operation in the Gambat South Block. Moreover, it represents the inaugural use of acid-soluble cement technology within the company’s portfolio. The accomplishment underscores PPL’s technical expertise, commitment to innovation, and dedication to maximizing production from mature fields.
The company stated that the information was shared in compliance with Section 96 of the Securities Act, 2015, and Clause 5.6.1 of the Pakistan Stock Exchange Limited Regulations. This disclosure ensures transparency and keeps stakeholders informed about key operational developments.
