RISA Reexamination of the Equations of Anisotropic Poroelasticity
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The anisotropic poroelastic constitutive model is reexamined in this article. The assumptions and conclusions of previous works, i.e., Thompson and Willis and Cheng, are compared and clarified. The micromechanics of ...
Theoretical and Numerical Models to Predict Fracking Debonding Zone and Optimize Perforation Cluster Spacing in Layered Shale
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Shale is a typical layered and anisotropic material whose properties are characterized primarily by locally oriented anisotropic clay minerals and naturally formed bedding planes. The debonding of the bedding planes will ...
Production Performance Analysis for Multi-Branched Horizontal Wells in Composite Coal Bed Methane Reservoir Considering Stress Sensitivity
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Coal bed methane (CBM) significantly contributes to unconventional energy resources. With the development of the drilling technology, multi-branched horizontal wells (MBHWs) have been put into the exploitation of CBM. In ...
Cylindrical Borehole Failure in a Poroelastic Medium
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Drilling a cylindrical borehole is the first and important step in oil mining. Borehole design and strength check are big problems of utmost importance. Biot introduced a poroelastic constitutive theory for porous rock ...
