Abstract
A flow conduit may have at least one orifice is in the vicinity of a flow source. The source is at least partially covered (and flow blocked by) an optional temporary coating or barrier. The flow pathway between the orifice and the source is temporarily blocked with a degradable material or barrier. The material disintegrates (e.g. under the influence of time or temperature) to optionally produce a product that removes the temporary coating in the area adjacent the barrier. The method is useful in one non-limiting context of recovering hydrocarbons where the flow conduit is the casing or liner of the well and the flow source is a subterranean reservoir where the temporary coating is a filter cake.
