A bridge plug assembly includes a tee bushing including a base and a stem, a coned bushing having a conical section and defining a bore that is configured to receive the stem, a molded assembly that is moveable over the conical section from an initial position to a set position, and a seal. The conical section is configured as a wedge such that when the stem is forced into the conical section during a setting process, the molded assembly and the seal move over the conical section from the initial position to the set position and expand radially outward by a wedge action of the conical section against a well casing. The molded assembly includes a slip assembly having a plurality of slip segments, over-molded with an elastomer. All components are made of dissolvable materials so as to reopen the well casing over time to its original inner diameter.

Dissolvable bridge plug assembly

A pipestring () wherein the leading coupling portion () of a first pipe segment () and the trailing coupling portion () of a second pipe segment () are coupled together. A leading seal part () is installed in the leading coupling portion () of the first pipe segment () and a trailing seal part () is installed in the trailing coupling portion () of the second pipe segment (). The seal parts () interface to form a fluid seal between the composite pipe segments (), and also to provide an electrically conductive path between their electrical lines ().
