Energy Science &Engineering, Volume 13, Issue 3, Page 1062-1078, March 2025.Increasing cavity temperature causes an exponential increase in thermal stress and the number of created cracks. Therefore, UCG cavity growth escalates with an increasing cavity temperature ABSTRACT The mechanism of cavity growth in a UCG process is mainly dependent on the presence of fractures and microcracks in the coal seam.

Journal of Rock Mechanics and Geotechnical Engineering, 2014 Hydraulic fracturing (HF) technique has been extensively used for the exploitation of unconventional oil and gas reservoirs. HF enhances the connectivity of less permeable oil and gas-bearing rock formations by fluid injection, which creates an ...

Parallelization of the Mesh Refinement Algorithm of the FDEM Program Package
, 2007 The Finite Difference Element Method (FDEM) program package is a robust and efficient black-box solver. It solves by a Finite Difference Method arbitrary non-linear systems of elliptic and parabolic partial differential equations under arbitrary non-linear boundary conditions on arbitrary domains in 2-D and 3-D, given by a FEMmesh.

Recent Developments in Multiscale and Multiphase Modelling of the Hydraulic Fracturing Process [PDF]
, 2015 Recently hydraulic fracturing of rocks has received much attention not only for its economic importance but also for its potential environmental impact. The hydraulically fracturing technique has been widely used in the oil (EOR) and gas (EGR) industries,

Fracture development around deep underground excavations: Insights from FDEM modelling
Journal of Rock Mechanics and Geotechnical Engineering, 2014 AbstractOver the past twenty years, there has been a growing interest in the development of numerical models that can realistically capture the progressive failure of rock masses. In particular, the investigation of damage development around underground excavations represents a key issue in several rock engineering applications, including tunnelling ...
