Oil and Gas

The drilling of oil and gas wells and the extraction and transportation of oil and gas involve systems that need to be designed for severe environmental conditions. Oil wells can extend several thousand meters in depth, and the oil and gas is transported through long pipelines that may be laid or buried in ground or seabed. The reservoirs containing the oil can subside, oil wells can erode, and bore wells can collapse. These phenomena can affect the reservoir yield and the useful life of oil wells. Simulation can help predict the useful life of reservoirs and assist with the design of extraction techniques for maximum yield. Additionally, the oil-bearing formation may be subjected to hydraulic fracture, and the effects of such fractures on the oil flow needs to be predicted.

The Abaqus Unified FEA product suite provides realistic simulation solutions that allow accurate predictions of soil deformation and reservoir subsidence when used in conjunction with multiphase reservoir simulation codes. You can utilize a wide range of geotechnical material models for modeling the formation material. Our pre- and postprocessor and sophisticated solvers provide a reliable solution for coupled stress-diffusion analyses.Contact modeling capabilities can be used for the efficient simulation of bore-hole collapse, and the the erosion modeling capability and pore-pressure cohesive elements can be used for simulating sand production in oil wells and hydraulic fracture phenomena, respectively.
