Non-explosive method for equalizing pressures between tubular strings
Welltec Puncher - efficient, safe, non-explosive operations for drill pipe, liner, tubing and casing recovery operations.
The Welltec Puncher provides an efficient, e-line conveyed, non-explosive method for equalizing pressures between tubular strings.
The Welltec Puncher provides an efficient, e-line conveyed, non explosive method for equalizing pressures between tubular strings. Its innovative design quickly creates a controlled diameter hole in the tubular at the target depth for pipe recovery or completion removal without the use of explosives.
Utilizing a fast, drilling technique, the Welltec Puncher produces a precise, uniform hole. The puncher can be run slick to any depth in the well or equipped with a ‘no-go’ for a hole punch at an exact depth. Multiple holes can be drilled in a single descent and it can be deployed independently or with other tools. It can be combined with the Well Tractor® for punching in highly deviated or horizontal wells.
