SUBTERRANEAN FLOW BARRIERS CONTAINING TRACERS

摘要

Some aspects of the present disclosure include monitoring fluid flow in a subterranean reservoir. In some implementations, a sealant mixture is injected into a subterranean reservoir to form a flow barrier in the subterranean reservoir. The sealant mixture includes a sealant material and a tracer. The tracer may be stored in the flow barrier, and the tracer may be displaced from the flow barrier, for example, by fluid flow in the subterranean reservoir. The displaced tracer may be detected, for example, in fluid produced into a well bore in the subterranean reservoir. Fluid flow in the subterranean reservoir may be analyzed based on detection of the tracer.
