Abstract
A system and method for jet perforating within a well are disclosed. A jet perforating tool configured to be lowered inside a production tubing string comprises a tool body with a passage, an inlet in the upper section, perforating jets in the lower section, and a stepped outer diameter configured to seat on a production tubing string restriction such as a seat nipple. The tool may be lowered into the production tubing string without the need to trip the production tubing string in and out of the wellbore.
