Review on the Influence of Slippery Water Imbibition on the Adsorption and Desorption of Shale Gas

With the continuous growth of global energy demand, shale gas, as a new oil and gas resource, has set off a boom of exploration and development all over the world. The desorption and diffusion of gas during the production process affect the production situation of shale gas wells in the middle and later stages. To enhance the investigation of the principles and methodologies governing shale gas adsorption and desorption, The features and factors influencing shale gas desorption are outlined through a comprehensive review of pertinent literature both domestically and internationally. The common adsorption models are summarized, The presence of slickwater not only impacts the pore structure and permeability of shale reservoirs but also influences the adsorption and desorption of methane. In previous studies, there are many studies on spontaneous imbibition of fracturing fluid in shale, but with the expansion to deep and high temperature and high pressure formations during mining, pressure imbibition of slippery zone will affect the efficiency and output of shale gas mining, which is of greater significance in actual mining, helping to predict the desorption process of shale gas more accurately, and providing scientific basis for the effective development and utilization of shale gas resources.
