In recent years CO 2 injection in shale has been investigated with aim to enhance shale gas
recovery (ESGR) and permanently sequester CO 2. This paper reviews the state of research …

The concept of increased methane recovery with simultaneous CO 2 sequestration in
unconventional reservoirs like gas shales has been studied extensively. A clear …

As the typical unconventional reservoir, shale gas is believed to be the most promising
alternative for the conventional resources in future energy patterns, attracting more and …

In this paper, the pore structures of three different rank coals sampled from China
(anthracite, bituminous coal and lignite) were characterized by CO 2 and N 2 adsorption …

Understanding methane adsorption behavior on deep shales is crucial for estimating the
original gas in place and enhancing gas recovery in deep shale gas formations. In this …

Accurately predicting gas adsorption in shale gas is essential for estimating production
capacity and optimizing extraction processes. However, the complex nature of shale …

Abstract Supercritical carbon dioxide (ScCO 2)-based fracturing technology associating with
CO 2 enhanced shale gas recovery is a promising technology to reduce the water …

The methane occurrence in coal is significant for coalbed methane (CBM) gas-in-place (GIP)
resource, production dynamics prediction, and development programming. The high …

A thorough study of the adsorption behavior of shales to methane (CH 4) and carbon dioxide
(CO 2) is critical for carbon dioxide sequestration in shale gas reservoirs and enhanced …

Shale gas contributes significantly to current global energy consumption, and an accurate
estimation of geological gas-in-place (GIP) determines an optimal production plan. As the …
