Appl. No.:

15/514030

Inventors:

International Classification:

E21B 33/038
E21B 29/02
E21B 33/14

Abstract:

A sealing tool for conveyance within a tubular member within a wellbore extending into a subterranean formation. The sealing tool includes a mandrel and a eutectic sealing material disposed about the mandrel. The eutectic sealing material has a eutectic temperature at which the eutectic sealing material melts. The sealing tool also includes means for heating the eutectic sealing material to at least the eutectic temperature. The eutectic sealing material is transferred onto an inner surface of the tubular member by activating the heating means to heat the eutectic sealing material to at least the eutectic temperature to melt the eutectic sealing material.

Abstract:

A technique facilitates forming cavities, e.g. perforations, into a geological formation. A jetting tool is moved downhole into a borehole, and an abrasive fluid is pumped down through the jetting tool. The abrasive fluid is discharged under pressure through a plurality of jetting nozzles to form jets of the abrasive fluid which act against a surrounding wall, e.g. a casing or other borehole wall. The jetting nozzles, and thus the jets, are oriented such that a rebound effect of the jets does not detrimentally impact the jetting tool. Consequently, the jets can be used to cut perforations through the surrounding wall and into the formation without eroding or otherwise detrimentally affecting components of the jetting tool.
