(Bloomberg) — ExxonMobil is reinforcing its long-term commitment to expanding fossil fuel production, anticipating that global demand will “remain largely unchanged” through 2050. According to Dan Ammann, president of Exxon’s upstream division, the energy giant is focused on sustained investment in oil and gas projects that it expects to remain essential for decades, rather than reacting to short-term trends. He spoke at the BloombergNEF “Barrel of Tomorrow in the Age of AI” conference in Houston on Thursday. Exxon aims to double its LNG sales by 2030 and is channeling significant investment into oil developments in Guyana and the Permian Basin. “We take a long-term view based on the fundamentals, and we invest behind that, Ammann said. “Our long-term view of the global energy equation is that the demand for energy is going to continue to grow.” Exxon has maintained its fossil-fuel-centered approach despite international climate objectives. Ammann said this strategy has served it well compared with other oil companies that pivoted to renewable energy only to come back to oil and gas when the returns were lacking.  “We saw some oil and gas companies, five, six, seven years ago say they were going to reduce production 40% by 2030,” he said. “There was literally no math you could do to suggest that was a good idea.” In its Energy Outlook report released last month, ExxonMobil noted that despite significant growth in low-carbon energy sources, oil and natural gas will still account for about 55% of the global energy mix by 2050. This is primarily due to a substantial increase in overall energy demand. The company stated that while oil demand is expected to level off around 2030, natural gas will fill the energy gap. “We see material growth on the gas side,” Ammann said. Exxon is nearing the startup of its Golden Pass LNG terminal, a joint project with QatarEnergy located on the Texas Gulf Coast, with operations expected to begin in the coming months. The company also plans to finalize investment choices for major ventures in Mozambique and Papua New Guinea by the end of 2026.

The ultra-high pressure valve stem and seat seal series products, designed and manufactured by JST Seals, have been successfully integrated into China's first 7-1/16" ultra-high pressure valve set developed by a renowned domestic petroleum equipment manufacturer. Rated at 25,000 PSI (175 MPa) with temperature class LX (-46°C to 180°C), the system has passed DNV-witnessed API 6A PR2F performance testing for valves after two months of rigorous gas-seal validation. This milestone marks the joint achievement of third-party DNV certification by JST Seals and its strategic client. Applications of API 6A Valves API 6A valves are primarily used in well control equipment for oil and gas drilling and completion operations. They perform critical functions including connecting, controlling, and regulating hydrocarbon flow paths, ensuring safety during routine production management such as well interventions, production testing, fracturing, and paraffin removal. Significance of 25,000 PSI Valve Certification Amid global innovations in shale fracturing technology and rapid advancements in electric-driven fracturing systems, the industry demands higher-pressure and larger-bore equipment for wellhead master valves and fracturing valves. This DNV-certified 25,000 PSI (175 MPa) large-bore valve meeting API PR2F requirements represents a major technological breakthrough for Chinese wellhead valves in extreme conditions involving ultra-high pressure, high flow rates, and heavy proppant loads. It also demonstrates the successful application of JST Seals's sealing solutions in ultra-high-pressure domains. As a leading Chinese specialist in multi-domain sealing technology, JST Seals remains committed to continuously upgrading products through market-driven R&D and implementing efficient manufacturing. We will continue delivering premium sealing solutions and expert technical services to our global partners.
