We present a fluid pressure and deformation analysis for geological sequestration of carbon dioxide based on a simplified hydro-mechanical model. This model includes the geomechanical part that relies on the theory of linear elasticity, while the fluid flow is based on the Darcy’s law. Two parts are coupled together using the linear poroelasticity theory. For a typical geological sequestration ...

Geomechanical monitoring of the rock mass state is an actively developing branch geomechanics, in which it impossible to distinguish a single methodology and approaches for solving problems, collecting analyzing data when seismic systems. During mining operations, all natural factors are subject changes. mass, changes structural inhomogeneities most clearly manifested: existing revealed; there ...

Fracture characteristics—such as orientation, type, fluid storage capability, and permeability—are complex yet essential information for understanding fractured reservoirs. Fractures are often perceived as permeable pathways, although many fractures partially or completely inhibit permeability within a reservoir. For example, opening-mode fractures (joints) may be partially or entirely sealed h...

Zonal disintegration have been discovered in many underground tunnels with the increasing of embedded depth. The formation mechanism of such phenomenon is difficult to explain under the framework of traditional rock mechanics, and the fractured shape and forming conditions are unclear. The numerical simulation was carried out to research the generating condition and forming process of zonal dis...

Wei AH platform is a composed of 8 horizontal wells in Weiyuan shale gas area. The number faults the area small, and natural fractures are locally developed. Therefore, it necessary to take volume reconstruction as core mining technology establish geology-engineering integration model for according concept. On basis geological model, combined with one-dimensional rock mechanics profile, geomech...
