Development of Casing Leak Measurement and Repair Tools. Volume 1. Final Report,April 1, 1991-May 15, 1992

摘要

The report covers research into the development of a tool to repair small leaksin gas storage wells. These small leaks occur at the threaded connection between adjacent casing sections. The thread, a nonsealing type, relies on pipe dope to act as a sealant. As the pipe dope ages, it drys out and the connection begins to leak. Concepts were developed and evaluated for a tool that runs into the well on a wireline, packs off around the leaking joint and injects a sealant into the thread. Results from laboratory tests on sealants are also reported.
