Abstract
A tubing punch and setting tool (TPST), operating on a single run for improved well bore intervention. The tool includes a setting tool for connecting to and setting a reference tool in a tubing string, a punch tool for punching holes in the tubing string wall, and actuation means to trigger the sequencing of the setting tool and the punch tool. The tool can be run on wireline, e-line or coiled tubing and allows a reference tool to be run and set on the same trip as punching holes in the tubing string. The reference tool can be an anchor tool. With the distance known accurately between the anchor tool and the punched holes, a shortened retrofit gas lift straddle can be deployed.

A tubing punch and setting tool (TPST) for running and setting a reference tool in a tubing string in a well bore and for punching at least one hole in the tubing string on a single trip in the well bore, the TPST comprising:
- a substantially cylindrical body having a first end adapted for connection to conveyancing means;
- a setting tool with means to connect to the reference tool at a second end;
- a punch tool comprising a substantially cylindrical body including at least two punch assemblies arranged perpendicularly to a central axis of the body, a hydraulic fluid chamber including a boost piston to compress the fluid and a fluid pathway, from the chamber, to deliver the compressed fluid to the punch assemblies and thereby operate the punch assemblies;
- at least two power delivery module;
- and, an actuation means located between the ends;
- wherein the actuation means adapted to trigger first power delivery module to power the setting tool to set the reference tool against the tubing and trigger second power delivery module to power the punch tool to punch at least one hole in the tubing.
A single trip well intervention method, comprising the steps;
- (a) locating a reference tool on a setting tool of a TPST, the TPST comprising:
- a substantially cylindrical body having a first end adapted for connection to conveyancing means;
- a setting tool with means to connect to the reference tool at a second end;
- a punch tool comprising a substantially cylindrical body including at least two punch assemblies arranged perpendicularly to a central axis of the body, a hydraulic fluid chamber including a boost piston to compress the fluid and fluid pathway, from the chamber, to deliver the compressed fluid to the punch assemblies and thereby operate the punch assemblies;
- at least two power delivery module;
- and, an actuation means located between the ends;
- wherein the actuation means triggers the power delivery module to power the setting tool to set the reference tool against the tubing and triggers the power delivery module to power the punch tool to punch at least one hole in the tubing;
- (b) running the TPST into a tubing string until the punch tool is at a desired depth to locate a punched hole through the tubing;
- (c) triggering first power delivery module to set the reference tool against a wall of the tubing using the setting tool;
- and
- (d) triggering second power delivery module to punch at least one hole in the tubing using the punch tool.

- (b) running the TPST into a tubing string until the punch tool is at a desired depth to locate a punched hole through the tubing;
- (c) triggering first power delivery module to set the reference tool against a wall of the tubing using the setting tool;
- (d) triggering second power delivery module to punch at least one hole in the tubing using the punch tool;
- (e) unlatching the setting tool from an anchor tool;
- (f) retrieving the TPST;
- (g) running a gas lift straddle and latching it to the anchor tool;
- (h) setting the packing elements on the straddle;
- and
- (i) commencing gas injection through the punched holes.
