Shale plays an important role as cap rock above oil and gas reservoirs and above e.g. CO2 storage sites, as well as being source and reservoir rock in development of so-called unconventional reserves. Shale anisotropy needs to be accounted for in geophysical as well as geomechanical applications. This paper presents a brief description of anisotropic poroelasticity theory, and compares it to its more familiar isotropic counterpart. Experiments performed with field shales are presented, and thedoi:10.1190/segam2018-2994785.1 fatcat:ywphbsgjg5fwvmhlo7hylnmtze
