... pressure above bubble point pressure. The DSC experiments performed in this work demonstrate changes in the phase behavior of oil (light Wyoming Crude) in presence of kerogen (type I) due to nano meter range pores and preferential absorption by kerogen matrix. Suppression of 10 °C in the bubble...

... Abstract In liquid rich shale plays, the hydrocarbons may remain associated with the parent kerogen. During catagenesis of kerogen in the geologic history, the kerogen is converted to hydrocarbons. A fraction of the generated hydrocarbons is expelled from the residual kerogen matrix, while the...

... Abstract Shale gas reservoirs are fine-grained, organic-rich rocks with a well-developed pore network structure within the organic matter (kerogen). Organic pores in shale reservoirs exhibit small radii in the range of 0.5 to 100 nanometers, which indicate that non-Darcy flow mechanisms are...

...%. Therefore, efficient enhanced oil recovery methods are highly desired to improve shale oil recovery. As an essential component of shale, kerogen plays a key role in generation, adsorption, storage and migration of hydrocarbons in shale as well as the geomechanical properties of shale. On the other hand...

Otherwise pessimistic values of OGIP and recoveries will be obtained by ignoring any of these mechanisms. This paper presents a new easy-to-use Material Balance...

The large surface area of kerogen due to its nanopore structure indicates that volume taken by adsorbed gas can be a significant part of the total porosity, and should not be neglected. Accuracy of porosity...

... Organic material, deposited and buried under layers of sediments, undergoes digenesis. Due to increasing depth of burial and temperature, it alters to a more stable form called kerogen ( Tissot and Welte, 1984 ). The alteration or maturity of the organic matter depends on the burial depth and the...
