International Classification:

E21B023/06

US Classification:

166/181000, 166/123000

Abstract:

A releasing mechanism for releasing a hydraulically actuated setting tool from a downhole tool is provided. Preferably, the downhole tool to be released is a wellbore sealing tool such as a bridge plug, packer or inflatable packer. The releasing mechanism comprises an adapter having a body, a connector above the body connected to the setting tool, and a lower portion. The releasing mechanism further comprises a releasable connection which releasably connects the lower portion of the adapter to a mandrel within the bridge plug or other sealing tool. In one embodiment, the releasable connection defines a frangible body disposed within the plane of the circumferential bore of the bridge plug mandrel. In another arrangement, the releasable connection defines both a frangible body and threaded collet fingers which releasably engage matching threads on the outer surface of the mandrel of the bridge plug or other wellbore sealing tool.

International Classification:

E21B 49/00

Abstract:

A system and method to determine health prognostics for selection and management of a tool for deployment in a downhole environment are described. The system includes a database to store life cycle information of the tool, the life cycle information including environmental and operational parameters associated with use of the tool. The system also includes a memory device to store statistical equations to determine the health prognostics of the tool, and a processor to calibrate the statistical equations and build a time-to-failure model of the tool based on a first portion of the life cycle information in the database.
