... oil reservoirs (Barati and Liang, 2014). However, less than 50% of the injected fracturing fluid is typically recovered after flowback periods (Bertoncello et al., 2014; Ge et al., 2015). The residual fracturing fluid in the fracture system and within the rock matrix contributes to a complex dynamic...

... Abstract The distribution of oil and water in tight sandstone reservoirs is complicated, with pore throat size and wettability being the main influencing factors. This study proposes an experimental method for determining core oil-water pore throat distribution based on nuclear magnetic...

... the production performance of the shale oil plays in relation to geologic and reservoir conditions. Overall, oil production per depth follows a bell-shaped profile that can be divided into three zones. The upper tail at depths of 400-6000 ft is too shallow for oil generation, and we interpret oil accumulations...
