Abstract
A subterranean reservoir is plugged by injecting a suspension containing solid particles of a resin capable of softening and resolidifying at the reservoir temperature. The particle sizes are correlated with the reservoir pore sizes so that particles are screened-out within and along the face of the reservoir formation. And, the particle compositions are correlated with the reservoir temperature so that the screened-out particles in and along the reservoir formation become fused into a substantially impermeable layer.
