Experimental Study on Prevention of Coal and Gas Outburst by Hydraulic Fracturing in High Gas Coal Mine in Yangquan Mining Area

Energy Science &Engineering, EarlyView.
ABSTRACT To investigate the hydraulic fracturing mechanism of high‐fluid wells in the Yangquan mining area, coal seams from the Xinyuan and Xinjing mines were selected as research subjects. Experiments were conducted using the TCQT‐III low‐permeability coalbed gas‐phase displacement and production enhancement apparatus, along with the FINESORB‐3120 ...

Study on Surrounding Rock Control Technology of Gob‐Gob Roadway Driven by Fully Mechanized Caving With Large Mining Height and Small Coal Pillar in Extra Thick Coal Seam

Energy Science &Engineering, EarlyView.
The analysis showed that the roof rock beam fractured above the side of the 5 m small coal pillar due to the influence of an anticline structure, leading to the proposal of an asymmetric control mechanism. Grouting pillars and individual supports were used for support, and the technology was successfully applied in the field, meeting the production ...

Research on the Micromechanical Properties of Minerals and Their Interfaces in Fractured Shale Reservoirs

Energy Science &Engineering, EarlyView.
ABSTRACT The mechanical properties of shale are key parameters affecting shale reservoirs. They influence the gas content in the shale reservoirs, expansion of hydraulic fractures, and microscopic changes in the in‐situ stress. In this paper, the shale of Longmaxi Formation in Changning area of Sichuan Basin is taken as the research object.

From Site Selection to Characterization: Assessment of Potential Reservoirs in the Lurestan Basin of Iran for Carbon Sequestration

Greenhouse Gases: Science and Technology, EarlyView.
ABSTRACT The increasing global focus on carbon sequestration underscores the need for comprehensive CO2 storage atlases, extending beyond Europe and America to other countries that are significant contributors to carbon dioxide emissions. This article addresses this imperative by examining the CO2 storage potential in the Lurestan area of Iran, with a ...

Geological Screening for CO2 Storage in Deep Saline Aquifers in the Lower Mainland British Columbia (LMBC), Canada

Greenhouse Gases: Science and Technology, EarlyView.
ABSTRACT Deep saline aquifers and depleted reservoirs are prime candidates for CO2 storage, but feasibility assessments remain limited in regions with little oil and gas activity, such as the Lower Mainland of British Columbia (LMBC), Canada. This study evaluates the CO2 storage potential of the Georgia Basin strata beneath the LMBC, focusing on three ...
