The pore structure of shale oil reservoirs is complex, and the microscale nanoscale effect obvious in development reservoirs. Understanding flow mechanism essential for optimizing plan enhancing recovery rate In this review, we briefly introduce occurrence status inorganic matrix organic (including shrinkage kerogen, diffusion transport channels, coupling diffusion, fluid matrix). Then, microfl...

A large number of oil and gas accumulations at deep ultra-deep depths, recently revealed in the world due to development drilling technologies, forces a revision theoretical ideas on many issues, including conditions formation hydrocarbon conservation zones high pressures temperatures, as well evaluating possibility reservoirs. Among most discussed, this regard, are issues determining processes...

Abstract The aim of this study is to provide a better understanding the type source input, quality, quantity, condition depositional environment and thermal maturity organic matter from Bukit Song, Sarawak, which has not been extensively studied for hydrocarbon generation potential. Petrological geochemical analyses were performed on 13 outcrop samples location. Two samples, having III mixed ke...

Abstract We investigated the palynological organic matter (POM) recovered from shale horizons, intercalating Nubian-type sandstones in middle Egypt, for paleoenvironmental reconstruction. Our palynofacies are dominated by either amorphous (AOM) or phytoclasts whereas palynomorphs relatively rare, but not uncommon. The categories revealed two different types, reflecting estuarine/tidal and fluvi...
