Abstract

An improved repair connector for a subsea tubular member and the method of making such repair. The improved repair connector includes a annular housing and an annular guide, said annular housing having internal grooves filled with pressure compensating material, a concave recess having serrations therein, a rib having a downwardly facing shoulder on the interior of said housing, threads on the upper interior of said housing for receiving a string, and means carried by said guide for sealing against the exterior of a string on which the connector is to be installed. Also, a band of brittle material is positioned within a groove in the exterior of the housing which generates a noise upon the deformation of the housing responsive to completion of the forming of the tubular member therein. The method of connecting the improved connector includes the steps of preparing the casing at a level below the defect, lowering the improved connector into engagement with the upper end of the prepared casing within the well bore, exerting deforming pressure within the upper end of the casing to deform the casing into sealing engagement within the internal grooves in the connector, and releasing and recovering the means generating the deforming pressure.
