High graphitization is responsible for low-resistivity shale development with poor reservoir quality. This paper provides an explanation of organic matter and determines the impact high graphite content on quality at Wufeng-Longmaxi Formation in Southern Sichuan Basin. Fine veins are frequently developed samples Ro > 3.5%, graphitized 25%, resistivity < 5 Ω•m, which dominated by three min...

The porochemoelectroelastic analytical models and solutions have been used to describe the response of chemically active and electrically charged saturated porous media such as clays, shales, and biological tissues. However, these attempts have been restricted to one-dimensional consolidation problems, which are very limited in practice and not general enough to serve as benchmark solutions for...

Gravitational loading or unloading due to deposition or erosion in sedimentary basins is one of the most common mechanisms responsible for abnormal fluid pressures in geologic formations. This paper examines the integrated response of fluid pressures to both deposition and erosion using vertical one-dimensional numerical models. The modeling results show that vertical loading and unloading of s...

Permeability is a crucial parameter for enhancing shale oil recovery through CO2 injection in oil-bearing shale. After injected into the reservoir, corrosion and adsorption-induced strain can change permeability of shale, affecting oil. This study aimed to explore influence on The deformation internal pore diameter induced by under different pressures was measured low-pressure nitrogen gas adso...

The objectives of this study are to (a) evaluate the exergy and energy demand for constructing a hydrofractured shale gas well and determine its typical exergy and energy returns on investment (ExROI and EROI), and (b) compute the gas flow and intrinsic exergy analysis in the shale gas matrix and created fractures. An exergy system analysis of construction of a typical U.S. shale gas well, whic...

We quantify the effect of a significant technological innovation, shale oil development, on asset prices. Using stock price changes on major news announcement days allows us to link aggregate stock price changes to shale development activity as well as other oil supply shocks. We exploit cross-sectional variation in industry portfolio returns on announcement days to construct a shale mimicking ...
