... failure under reservoir depletion since its mechanical strength becomes weaker. This paper investigates the effects of wormhole geometry and rock strength weakening on wormhole stability by coupled hydro-chemo-mechanical simulation. The acidizing process is firstly simulated using in-house acidizing...

Paper Number: ARMA-2019-0115
... ABSTRACT: Fault surface geometries and their natural textures impose dominant control on the slip potential and characteristics of induced seismicity when triggered by reservoir depletion. In this study, we perform refined re-interpretation of subsurface faults on reflection seismic which...

Paper Number: ARMA-10-342
... ABSTRACT: Reservoir depletion will cause in-situ stress reductions in both reservoir and overburden (caprock) sections. Horizontal and vertical stresses will also be affected by the depletion. Mud weights must be adjusted or a casing string must be set before drilling through depleted...

Paper presented at the Alaska Rocks 2005, The 40th U.S. Symposium on Rock Mechanics (USRMS), June 25–29, 2005
Paper Number: ARMA-05-791
... ABSTRACT: It is well established that uniaxial strain deformation condition better simulates the reservoir depletion response than hydrostatic deformation condition. As a result, pore compressibility and reservoir compaction estimated under uniaxial strain deformation condition are more...

... obeys the Mohr-Coulomb failure criterion. To pose the boundary value problem for the stress perturbations caused by reservoir depletion, the boundary conditions on the discontinuity sides have been derived using asymptotic analysis. A general boundary collocation technique for the solution of this class...
