Modeling the Strength of Water Shut-Off Baffles in Porous Formations

Resumo

Within the framework of a model of a perfectly plastic body, the strength of a two-layer water shut-off baffle adjacent to the trunk of a production well in a porous medium is investigated. The baffle is formed by pumping (with subsequent hardening) synthetic resin into the porous layer through the production well. In the problem parameter space, the domains with the satisfied strength and yield conditions of the outer and inner layers of the baffle are determined.
