HIGH TEMPERATURE, HIGH PRESSURE BACK-OFF SHOT TOOL

摘要

A back-off shot tool system includes a high-pressure resistant charge housing at least partially containing an explosive material. A booster charge is placed adjacent the explosive material to activate the explosive material upon actuation. The high-pressure resistant charge housing is formed from a material that is able to withstand high temperatures and pressures, such as a ceramic. In addition, the material of the high-pressure resistant charge housing is frangible so that it will fragment into small pieces that can be process or extracted from the well with fluid that is extracted from the region in which the back-off shot tool is deployed.
