Paper presented at the SPE/AAPG/SEG Asia Pacific Unconventional Resources Technology Conference, November 16–18, 2021
Paper Number: URTEC-208331-MS
... approach was developed to measure the cleat compressibility C f directly using high precision non-contact video extensometer, which was then validated by comparing with the data available in the literature. Given a horizontal stress, the obtained C f was adopted to analyse the aperture variation...

... relative to permeability that maximises the incremental NPV from GPI application. The next most significant parameters after permeability that influence the economic outcomes are fracture porosity and coal compressibility. A larger SRV yields higher cumulative gas production over 30 years with up to 7.2...

Paper presented at the SPE/AAPG/SEG Asia Pacific Unconventional Resources Technology Conference, November 18–19, 2019
Paper Number: URTEC-198226-MS
... Abstract This project establishes a new workflow to improve the dewatering efficiency of under-saturated CSG (Coal Seam Gas) reservoirs, while minimising reservoir damage related to coal compressibility. The over-arching goal is to maximise long-term productivity of wells to improve...

... compressible two-phase flow in coal, accounting for gas desorption, matrix shrinkage, heterogeneous permeability distribution, and cross-flow. Fractured porous medium is modelled by a dual-porosity radial model. Stress-dependent permeability and matrix shrinkage effects are modelled using the Palmer-Mansoori...

..., thickness, seam extent, initial reservoir pressure, compressibility and porosity. The stress-dependency of permeability obeys the Palmer and Mansoori (1998) model. A coefficient (Α) relates seam radius, thickness, porosity, compressibility, permeability, and initial pressure. It is used to aid...
