Purpose is the development of mathematical models to evaluate deformation parameters rock mass-well geological and engineering system within anisotropic media. Methods. Both neural modeling a stress state under conditions uncertainty has been applied for studies. From viewpoint modeling, analysis probability factors, complicating drilling, should involve number assumptions strength characterist...

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...

Abstract This paper presents a coupled finite element approach for modeling geomechanical effects induced by production/injection processes in petroleum reservoirs. The module developed employs coupled- reservoir analysis using CMG IMEX® as the flow simulator and program MATLAB® stress–strain simulator, two-way explicit partial coupling scheme. mechanical problems are change of effective stress...
