Investigation of Poroelastic Effects on In-Situ Stresses and Concomitant Effects on Seal Integrity: Comparison of Analytical and Numerical Models

The primary objective of this project is to apply a number of geomechanical modelling tools to a specific poroelastic problem (fluid withdrawal and subsequent injection into a pinnacle reef), and to assess the strengths and weaknesses of these modelling tools. A secondary objective is to use the modelling results to assess: (i) the critical pore pressures at which the reservoir’s seal could be compromised, for the specific pinnacle reef problem being analysed; and (ii) the locations and types of rock failure processes that would negatively impact the seal’s integrity if these critical pressures were exceeded.
