A Novel Numerical Study of Reservoir-Induced Subsidence and Upheaval Effects on Bearing Capacity of Offshore Piles
This paper presents a geomechanical assessment of the effects of reservoir-induced deformations during production and injection operations on the bearing capacity of offshore piles. Injection/extraction of fluids deep into/from reservoirs results in spatiotemporal deformations of the reservoir rock, which translate into seabed movements. This can impact the performance of offshore foundations specifically in an event of a hurricane. A numerical model is developed in this study to replicate a driven pile from the EC368A platform. The model is calibrated versus real data from literature. Next, the geomechanical response of the overburden to injection and production flow is incorporated in the model in a novel manner. Finally, the pile’s ultimate bearing capacity is assessed for three cases: trivial subsurface deformations, injection-induced deformations, and production-induced deformations. Results confirm the proposed hypothesis that reservoir-induced deformations can notably affect pile’s performance, and thus should be incorporated in the design of offshore platforms.
