Technology Focus: Natural Gas Processing and Handling (April 2025)

Natural gas processing includes an array of operations, including natural gas dehydration, sweetening, liquefaction, fractionation, knockout of inert gases, transportation, and transmission to sales point. These processes require interactions of different phases of dry-gas and wet-gas pressure, volume, and temperature. These interactions are demonstrated using equations of state, simulations, and models. Recently, artificial intelligence (AI), deep learning (DL), and machine learning (ML) have taken natural gas processing and handling on a new trajectory, replacing complex simulation runs. Challenges related to natural gas processing and handling such as gas leaks, carbon emission, and gas flaring are being managed using innovative processes developed through the operations of AI, ML, and DL. In reviewing a collection of SPE papers with top-notch innovations in natural gas processing operations, it is clear that technologies have become smart, with researchers and technology experts moving with the trends to make improvements on previous operations. Researchers and technology experts have made novel and innovative contributions to natural gas processing and handling using robotic and smart technologies for leak detection, carbon footprinting, and flare management. Smart technologies have also improved the operation processes around gas dehydration, sweetening, liquefaction, and fractionation. These have replaced complex backend simulations and have made natural gas processing seamlessly automated. Truly, AI, DL, and ML may not be optimally efficient in other climes, but they have shown reasonable efficiency in surface production operations, especially natural gas processing, because many of these operations have been automated. This trend is seen in the papers summarized here. Summarized papers in this April 2025 issue.
