... to reduce aquifer influx into and gas migration from a coal seam gas (CSG) well near a subcrop with an aquifer connection. Similarly, barrier applications can improve gas production and recovery for undersaturated coal seams where conventional shielding methods to reduce water influx and improve desorption...

... Abstract A variety of different compressibility terms, including cleat compressibility and bulk compressibility, are used when modelling coal seam gas (CSG) reservoirs. The relationship between different compressibility terms is often theoretically straightforward, but in practice may be much...

... Abstract Coal geomechanical properties are of importance in various applications, including drilling in coal seams, ensuring long-term borehole stability, and predicting the permeability evolution in coal seam gas reservoirs. However, coal is highly cleated and fragile. Obtaining standard drill...

... Abstract Within the Queensland energy industry, unconventional gas, such as Coal Seam Gas (CSG) production holds significant importance. This study employs the Continuous Wavelet Transform (CWT) to analyze variations in CSG production, aiming to comprehend its complex production dynamics...

... of coal seams. For Kalbar-1, coal seam gas reservoir properties are dominated by volcanic intrusions in the area. A major volcanic intrusion of approximately 60m in thickness and a few minor intrusions are identified as major players controlling gas content and shape of methane adsorption Langmuir...

... Abstract A trial was conducted by Origin Energy to study the feasibility of re-injecting produced coal seam gas (CSG) also known as coal bed methane (CBM) back into depleted coal formations. The trial specifically set out to identify any practical limitations of re-injecting gas as a means...

...). In Victoria, coal seam gas and shale gas are regulated by different legislation. Shale gas is classified as petroleum, and exploration for it is regulated by the Petroleum Act 1998 (Vic) ("PA"). Coal seam gas is regulated under the Mining Act. The Petroleum Act defines petroleum, as a naturally occurring...
