Frictional properties of natural and induced fractures in two types of shales Open
This paper presents results of direct shear tests on two types of shales; Rurikfjellet from Svalbard, Arctic Norway and Draupne from Ling Depression, the North Sea. Rurikfjellet formation is part of a caprock system for the proposed CO 2 s…

An Analytical Solution for Pressure-Induced Deformation of Anisotropic Multilayered Subsurface Open
We present a generalized Geertsma solution that can consider any number of finite-thickness layers in the subsurface whose mechanical properties are different from layer to layer. In addition, each layer can be assumed either isotropic or …

Generalized Geertsma Solution for Isotropic Layered Medium Open
We report a generalized Geertsma solution with which we can calculate the surface deformation from a subsurface made of an arbitrary number of isotropic homogeneous layers and a thick reservoir at any depth. We validate the generalized Gee…

Effect of brine-CO<sub>2</sub> fracture flow on velocity and electrical resistivity of naturally fractured tight sandstones Open
Fracture networks inside geologic [Formula: see text] storage reservoirs can serve as the primary fluid flow conduit, particularly in low-permeability formations. Although some experiments focus on the geophysical properties of brine- and …
