Paper Number: SPE-217281-MS
... 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...

...). 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...
