ANOMOLOUS TWO-PHASE FLOW BEHAVIOR IN FRACTURED SANDSTONE EXPLAINED USING X-RAY COMPUTED TOMOGRAPHY

Freddy Alvarado, Phillip Halleck, Abraham Grader & Freddy Alvarado
Understanding fracture morphology in terms of a porous media is necessary for accurate simulation of multiphase transport in fractured rocks. Although ambient- stress methods for obtaining fracture morphology exist, previous research lacks the ability to map fracture closure as a function of stress or the distribution of immiscible phases in the fracture. A twenty-five-millimeter cylindrical sandstone sample was artificially fractured in tension and placed under confining stress in an x-ray transparent vessel. The fracture morphology...
