82% increased productivity through increased deployment
The reach capabilities of the CT depend on its physical characteristics, the completion size and wellbore geometry. Welltec’s Well Tractor® CT is a hydraulic driven, modular tool which attaches to the end of the CT and takes it further into the wellbore. In extended reach fields it’s important to further the reach of the coiled tubing in order to maximize the impact of the stimulation. Anything in front of the CT must be stimulated with a less effective, bull heading technique.
The value derived from this increase in stimulated reservoir for the wells reviewed was an 82% boost in productivity index.
The original Well Tractor was in fact a version designed to run on Coiled Tubing. Harnessing the fluids pumped from surface it is an essential tool for overcoming helical buckling or washouts.
