Lithofacies types, reservoir characteristics and silica origin of marine shales: A case study of the Wufeng formation–Longmaxi Formation in the Luzhou area, southern Sichuan Basin

open access: yesNatural Gas Industry B, 2022
Shale, which is a fine-grained sedimentary rock, differs in reservoir quality (RQ) and completion quality (CQ) as the result of variations in its mineral and organic-matter compositions. The RQ and CQ directly affect shale gas exploitation.

A compositional model for CO2 flooding including CO2 equilibria between water and oil using the Peng–Robinson equation of state with the Wong–Sandler mixing rule

open access: yesPetroleum Science, 2019
This paper presents a three-dimensional, three-phase compositional model considering CO2 phase equilibrium between water and oil. In this model, CO2 is mutually soluble in aqueous and hydrocarbon phases, while other components, except water, exist in ...

Oil and Gas Shales

open access: yes, 2018
Organic matter dispersed in shales and mudstones is 10,000 times more abundant than that occurring in concentrated forms such as oil, gas, coal, and gas hydrates. So-called shale plays, distributed across all continents, are fairways where shale gas and shale oil might be extracted economically from targeted volumes of what is an extremely large ...
