In an infinite or semi-infinite domain, a petroleum reservoir can be simulated as a displacement discontinuity, permitting use of an efficient displacement discontinuity boundary element method to calculate surrounding stress and displacement changes. A 3D poroelastic finite element method is used to account for the local reservoir model. By coupling the displacement discontinuity and finite element models, a 3D poroelastic reservoir in an infinite or semi-infinite domain is simulated. The numerical model has been verified and numerical examples are given. Results show that the relative deformation properties of surrounding strata have significant effects on pressure drawdown and reservoir deformation during production, and thus should be taken into account. 1-4 Journal of Petroleum Science & Engineering 64 ARTICULO Yin, Shunde 41080 Dusseault, Maurice B. 9686 Rothenburg, Leo 41081 169687 169687 0 0 0 0 237506 BAAB BAAB 2026-03-05 200044495 0 200044495 2026-03-05 15:11:55 2026-03-05 ARTICULO
