Particle motion in granular systems is common nature and industrial processes. Along with particle size density, the shape of particles also plays a crucial role dynamic behavior such systems. To capture irregular morphology particles, we have proposed an image-based discrete element method which effect fluid considered. We considered four cases to study how ambient simultaneously affect proper...

In this study, a 3D multicomponent multiphase simulator with a new fracture characterization technique is developed to simulate the enhanced recovery of coalbed methane. In this new model, the diffusion source from the matrix is calculated using the traditional dual-continuum approach, while in the Darcy flow scale, the Discrete Fracture Model (DFM) is introduced to explicitly represent the flo...

A digital model of geomechanical processes in a structurally heterogeneous geo-massif with consideration for the influence natural and technogenic forces was developed. Based on results numerical modeling, regularities stress change, convergence roof soil rocks, stability coal pillars between production development workings were revealed an increase depth thickness interbed rocks within excavat...

The Finite Element modelling of geological faults by penalty contact elements may give rise to illconditioned stiffness matrices with the convergence of iterative solvers accelerated, or even allowed for, by the development and implementation of appropriate preconditioners. The present communication investigates the performance of three different block preconditioners in a realistic geomechanic...

Elliptic differential operators describe a wide range of processes in mechanics relevant to geo-energy applications. Extensively used reservoir modeling, the Finite Volume Method with TPFA can be consistently applied discretize only specific type application under severe assumptions. In this paper, we introduce positivity preserving Nonlinear Two Point Stress Approximation (NTPSA) based on rece...

Material properties is one of the most significant variables in terms efficiency. The sediment layer a coal pit mine has possibility sticking to equipment bucket and reducing its productivity, especially disposal area. Consequently, stickiness close definition adhesivity level; thus it may be associated with geomechanical properties. Various soil classification area was investigated identify re...

Abstract Pre-stack seismic inversion, well log analysis approach and empirical relations were adopted in this study to better estimate geomechanical properties of Ruby field with minimum error. The use conventional method alone evaluate oil/gas fields sometimes becomes problematic. Geomechanical divided into: elastic moduli [Young’s modulus, shear bulk modulus Poisson ratio ( PR )] rock mechani...
