The reduction of fluid pressure during reservoir production promotes changes in the effective and total stress distribution within surrounding strata.This evolution is responsible for many problems encountered (e.g.fault reactivation, casing deformation).This work presents results an extensive series 3D numerical hydro-mechanical coupled analyses that study influence geometry material properties on path.The path defined terms parameters quantify amount arching anisotropy occur production.The...
Hydraulic overpressure can induce fractures and increase permeability in a range of geological settings, including volcanological, glacial petroleum reservoirs. Here we consider an example induced hydraulic fracture stimulation tight-gas sandstone. Successful exploitation reservoirs requires networks, either naturally occurring, or generated through stimulation. The study seismic anisotropy provides means to infer properties such as the dominant orientation sets compliances. Shear wave...
ABSTRACT In this paper, we investigate production induced microseismicity based on modelling material failure from coupled fluid‐flow and geomechanical simulation. The model is a graben style reservoir characterized by two normal faults subdividing sandstone into three compartments. results are analysed in terms of spatial temporal variations distribution failure. We observe that hence potentially sensitive to not only fault movement but also fluid across faults. For sealing faults, confined...
A new approach to defining the effective fracture toughness for heterogeneous materials is proposed. This temporal averaging process dependent, incorporating crack velocity and material toughness. The effectiveness of technique investigated in context hydraulic through rock with a periodic plane strain model considered without fluid leak-off, more easily investigate different regimes (toughness/viscosity). Numerical simulations are used examine homogenisation strategy, comparison against...
We present a workflow linking coupled fluid-flow and geomechanical simulation with seismic modelling to predict anisotropy induced by non-hydrostatic stress changes. generate models from simulations examine the relationship between reservoir geometry, path anisotropy. The results indicate that geometry influences evolution of stress, which leads stress-induced Although is high for small reservoir, effect arching ability side-burden support excess load limit overall change in effective hence...
With the increasing demand for CO 2 storage in subsurface, it is important to recognize that candidate formations may present complex stress conditions and material characteristics. Consequently, modelling of injection requires selection most appropriate constitutive model best possible representation response. The authors focus on geomechanical behaviour reservoir material, coupled with a multiphase flow solution into saline-saturated medium. It proposed SR3 critical-state used, which...
Summary With the increasing demand for CO2 storage into subsurface, it is important to recognize that target formations like saline aquifers can vary significantly in their geomechanical and hydraulic properties. Consequently, modelling of injection requires selection most appropriate constitutive material model best possible representation response. The authors focus on behaviour reservoir material, coupled with multi-phase flow solution a saturated medium. It proposed use SR3 critical...

In this paper, we describe a workflow that integrates geomechanical, fluid-flow and seismic modelling can be used to predict the stress distribution evolution as well various attributes before during production. Poroelastoplastic constitutive model is incorporate matrix failure simulation, allowing strain hardening weakening develop within model. This especially important for reservoir path asymmetry. The material also enables prediction of when where occurs in model, us likely microseismic...
