Oil and Gas Development Company Limited (OGDCL) has discovered 19 new oil and gas reserves since 2023, strengthening Pakistan's domestic energy base and reducing dependence on costly fuel imports, with the combined output expected to generate import substitution worth nearly Rs1.2 billion per day. According to official documents available with Wealth Pakistan, the discoveries, spread across Sindh, Punjab and Khyber Pakhtunkhwa, have an estimated cumulative production potential of 17,123 barrels per day (BPD) of oil and 151 million standard cubic feet per day (MMSCFD) of natural gas. The documents indicate that OGDCL made five discoveries during FY2023-24, contributing an estimated 481 BPD of oil and 29.66 MMSCFD of gas. These discoveries are expected to reduce import expenditure by approximately Rs283.48 million per day. The exploration programme continued during FY2024-25, when another five discoveries added 947 BPD of oil and 34.49 MMSCFD of gas, generating an estimated daily import substitution of Rs279. 70 million. Exploration activity accelerated further during the first nine months of FY2025-26, with OGDCL making nine additional discoveries. These finds carry an estimated production potential of 15,695 BPD of oil and 86.95 MMSCFD of gas and are projected to reduce import expenditure by around Rs633.45 million per day. Among the most significant discoveries was the multi-zone hydrocarbon find at Baragzai X-01, which recorded a tested cumulative production potential of approximately 15,005 BPD of oil and 45.36 MMSCFD of gas. The company's reserve position also improved during the review period. According to the documents, OGDCL's Reserve Replacement Ratio (RRR)-which measures reserve additions relative to production-stood at 56 percent in FY2023-24, increased to 167 percent in FY2024-25, and remained strong at 153 percent during the first nine months of FY2025-26. As a result, the company's estimated reserve life expanded from 14 years to 17 years as of March 31, 2026, extending the sustainability outlook for its hydrocarbon reserves by three years. Alongside exploration, OGDCL continued to commercialise discovered resources by bringing 34 wells and fields into production during the review period. In FY2022-23, the company commissioned five wells, producing 990 BPD of oil and 18.28 MMSCFD of gas. During FY2023-24, 11 wells added 4,398 BPD of oil and 43.23 MMSCFD of gas, while eight wells commissioned in FY2024-25 contributed 744 BPD of oil and 41.80 MMSCFD of gas. During FY2025-26 up to April, another 11 wells entered production, with estimated output of 9,734 BPD of oil and 74.25 MMSCFD of gas. The company also intensified efforts to enhance production from existing fields. According to the documents, OGDCL carried out more than 65 rig workovers and over 295 rigless interventions, resulting in an estimated incremental production of approximately 17,000 BPD of oil and 90 MMSCFD of gas. The latest exploration and production data suggest that OGDCL has accelerated both reserve additions and field development s ince 2023, supporting Pakistan's efforts to expand domestic energy production while reducing reliance on imported fuels.
