For more than forty years, the Rock-Eval pyrolysis technique has been widely used to rapidly
assess the petroleum generating characteristics of organic matter in petroleum source rocks …

Water-based drilling fluids (WBDFs) are widely used for drilling oil and gas wells. Water-
based drilling fluids are considered economical and environmentally friendly compared to …

The big success in marine shale gas exploration and production made China the third
country worldwide to commercialize shale gas development. However, the Upper …

Understanding the governing processes of CO 2 huff-n-puff in shales is essential for
enhancing shale gas recovery and CO 2 sequestration. However, existing studies have not …

Understanding the heterogeneity of the nanoscale pore structure is critical for assessment of
hydrocarbon flow and storage in porous reservoirs. Multifractal theory is a powerful method …

We used molecular dynamics (MD) simulation to study adsorption behavior of oil within
nanoscale carbonaceous slits of shale systems. Results show that fluid density is not …

Tight oil reservoirs typically show a wide pore size distribution with pore sizes ranging from
several nanometers to several hundred microns, requiring a combination of several …

The Chang 7 tight oil reservoirs are important oil exploration targets in the Ordos basin. The
reservoirs are generally characterized by low porosity, low permeability and strong …

The purpose of this article is to make a comparative study on the pore structure of different
sedimentary facies shales developed in typical areas, China. Results show that the surface …

Nanoporosity of a shale gas reservoir provides essential information on the gas
accumulation space and controls the gas reserves. The characteristics of heterogeneous …
