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...

The article considers the problem connected with study of well drilling rates in complex reservoirs. Its solution is presented form a neural network model that takes into account structural, geomechanical and technological features «rock mass — well» system. possibility predicting method different strength structural-lithological characteristics massif, based on modeling, presented. purpose thi...
