Recent Advances in High-efficiency Development of Conventional/Unconventional Gas Reservoirs and CCUS TechnologiesTraditional fossil energy including oil and gas sources is anticipated to continue to dominate the energy market and the global energy demand is estimated to increase by another 60.0 % over the next few decades. Considering the current global warming issues, clean energy exploitation as well as CCUS technologies have gained more attention recently to mitigate the big gap between energy supply and energy demands as well as to reduce CO
2 emission. Compared with coal and oil, natural gas is a cleaner and more environmentally friendly resource with principal combustion products to be water vapor and carbon dioxide and it is expected to become the leading fuel in the US and other countries to satisfy the needs of industry and a growing population. Therefore, high-efficiency and low-carbon development technologies for gas reservoirs are always attractive.
The recovery of conventional gas reservoirs can be as high as 90%, while the recovery of unconventional gas reservoirs including tight gas, shale gas and deep-seated gas is generally lower than 45%. High-efficiency intelligent development of gas reservoirs, especially unconventional gas reservoirs is the important support of increasing consumption, and the key to high gas recovery lies on the significant advances in the exploitation technologies including fracturing technologies, novel numerical simulation methods, reservoir assessment technologies, etc. to facilitate the gas production process. Meanwhile, the CO
2 produced by gas combustion is also a threat to accelerate global warming, therefore, research on supporting CCUS technologies are also encouraged.
This Research Topic covers themes such as conventional and unconventional gas exploitation with advanced technologies, enhanced gas recovery technologies, reservoir assessment technologies and CCUS technologies. We seek for comprehensive reviews, experimental studies, numerical simulations, and field applications related to steady and high efficiency gas production.
