The shale gas revolution: Barriers, sustainability, and emerging opportunities

Abstract Shale gas and hydraulic refracturing has revolutionized the US energy sector in terms of prices, consumption, and CO2 emissions. However, key questions remain including environmental concerns and extraction efficiencies that are leveling off. For the first time, we identify key discoveries, lessons learned, and recommendations from this shale gas revolution

Shale gas exploitation: Status, problems and prospect

Fig. 2. Annual production of major shale gas plays in the world. Note: The data abroad are sourced from Refs. [14], [15], and the domestic data from Ref. [1]. Except for the Monteney and Muskwa shale gas plays in Canada of which the production data are shale gas production from 2011 to 2012, those of other plays are the data in 2015.

Shale gas reserves and production have been in a rapid growth in China owing to the Lower Paleozoic Wufeng and Longmaxi shale gas exploitation in the Sichuan Basin, which has become an important sector for the future increment of gas reserves and output in China. However, substantial progress has been

Elastic–Brittle–Plastic Behaviour of Shale Reservoirs and Its Implications on Fracture Permeability Variation: An Analytical Approach

Desorption of gas during production can cause shrinkage of the organic content of the rock. This becomes more important when considering the use of shales for CO2 sequestration purposes, where CO2 adsorption-induced swelling can play an important role. These phenomena lead to changes in the stress state within the rock

Enhancing recovery and sensitivity studies in an unconventional tight gas condensate reservoir

Sensitivity analysis of the key factors such as primary production duration, bottom-hole pressures, and fracture conductivity is conducted and their effects on the well production performance are analyzed. Results show that, compared with the simple depletion method, both the cumulative gas and condensate production increase with fluids injected. Produced gas

However, this article shows that the EU shale gas regulatory framework is not, “fit for purpose”. It will critically evaluate current European Union shale gas regulations and offer some recommendations for improvement.

Study of Gas Flow Characteristics in Tight Porous Media with a Microscale Lattice Boltzmann Model

Study of Gas Flow Characteristics in Tight Porous Media with a Microscale Lattice Boltzmann Model

Abstract To investigate the gas flow characteristics in tight porous media, a microscale lattice Boltzmann (LB) model with the regularization procedure is firstly adopted to simulate gas flow in three-dimensional (3D) digital rocks. A shale digital rock and a sandstone digital rock are reconstructed to study the effects of pressure, temperature
