Experiment and Simulation Study on the Special Phase Behavior of Huachang Near-Critical Condensate Gas Reservoir Fluid by Dali Hou, Yang Xiao, Yi Pan, Lei Sun, Kai Li

“…Due to the special phase behavior of near-critical fluid, the development approaches of near-critical condensate gas and near-critical volatile oil reservoirs differ from conventional oil and gas reservoirs. In the near-critical region, slightly reduced pressure may result in considerable change in gas and liquid composition since a large amount of gas or retrograde condensate liquid is generated. …”

“…The following conclusions were drawn: for organic-rich mixed shales and organic-rich clay shales, the TOC content is the highest; the pore volume, which is primarily provided by macropores and specific surface area, which is provided by mesopores, was the largest, thus providing more space for shale oil and gas reservation. The pores take on a shape either close to a parallel plate slit or close to or of an ink bottle. …”

Carbon circular utilization and sequestration in depleted hydrocarbon reservoirs: Towards a carbon-neutral China by Lin Wu, Zhengmeng Hou, Yang Li, Weidong Wang, Long Cheng, Junzhang Lin, Zhifeng Luo, Liangchao Huang

“…The technology of carbon dioxide (CO2) enhanced hydrocarbon recovery is favored over other Carbon Capture, Utilization, and Sequestration (CCUS) methods for achieving the “double carbon” goal in China due to its ability to sequester CO2 geologically while enhancing the recovery rates of oil and gas resources. However, current technologies face significant challenges, such as limited recovery enhancement capacity, as well as high costs and low efficiency in carbon utilization and sequestration. …”

Aquathermolysis of heavy oil catalyzed by transition metal salts and clay by Du, Yingna, Zhang, Liyuan, Jing, Rui, Li, Yongfei, Yang, Bo, Chen, Gang

“…Currently, researchers have indicated that inorganic minerals in reservoirs, such as clay minerals, carbonates and quartz, can catalyze the evolution of organic matter into oil and gas. Therefore it is reasonable to believe that the minerals in reservoirs may act as a catalyst support with the metal-containing catalyst added from outside during the thermal recovery of heavy oil. …”
