Title: Innovations of James J Sheng in Hydrocarbon Reservoirs
Introduction
James J Sheng is a prominent inventor based in Lubbock, Texas, known for his significant contributions to the field of hydrocarbon reservoir optimization. With a total of six patents to his name, Sheng has developed innovative methods that enhance oil recovery and improve production efficiency in shale reservoirs.
Latest Patents
One of Sheng's latest patents is titled "Method for optimization of huff-n-puff gas injection in hydrocarbon reservoirs." This method focuses on optimizing liquid oil production by utilizing huff-n-puff techniques to achieve an improved oil recovery factor. The process involves determining the optimum huff and puff times, the number of cycles, and soaking time under practical operation and reservoir conditions. The huff time is defined as the period during which the pressure near the wellbore reaches the maximum injection pressure, while the puff time is the duration required for the pressure to reach the minimum production pressure. Notably, soaking is typically not necessary during the huff-n-puff gas injection in shale oil reservoirs. The number of cycles is determined by the time it takes to reach the economic rate cut-off.
Another significant patent by Sheng is the "Method to generate microfractures by chemical reaction in low carbonate mineral content shale reservoirs." This innovative method involves injecting sulfate acid or a persulfate compound, such as ammonium persulfate, into conventional fracturing fluid. This reaction with shale carbonate components leads to the precipitation of gypsum crystals, thereby generating microfractures that enhance reservoir performance.
