The fluid flow modeling procedure including a critically stressed fracture analysis of coalbed methane reservoir: a case study of Upper Silesian Coal Basin, Poland

The geomechanical modeling turned out to be an essential component of the hydrocarbon exploration assisting reduction risk drilling issues and optimization hydraulic fracturing treatment. This study provides a workflow critically stressed fracture (CSF) analysis dedicated for coal layers. main focus paper is applying 1D mechanical models following modelling treatment describe behavior under impact stresses at wellbore scale. Another objective presented demonstration benefits 3D CSF understand contribution gained volume after seam. Interpretation orientation their vital effective development bed methane (CBM) resources as can responsible considerable part CBM production. Natural fractures faults contribute fluid flow through rock. It often noted that natural may not ambient stress state. However, during stimulation, optimally oriented sets have inclination become stressed. Hence, understanding recent state orientations significant well planning design. outcome this are comprehensive Earth (MEMs) analyzed wells explanation identified variable connectivity within zone subjected
