Placement of new fractures in a system that has been already depleted poses new challenges for operators. These challenges are due to the altered stress zones resulting from the expected pore volume depletion and corresponding pressure decline. In this study, effect of pore pressure depletion on horizontal stresses, and refracture propagation issues in a horizontal well are studied using a numerical method called displacement discontinuity method.en-USPoster
