Drill string applications tool
Abstract:
An apparatus and system for generating pressure pulses for enhancing and completing a well bore within a pipe or coiled tubing operation including: a valve longitudinally and axially positioned within the center of a pulser section, a gearbox, and an impeller. The main fluid flow is interrupted by the main valve which is operated by a controlled pilot fluid stream. The pilot fluid stream is controlled by a determined rotation of a gearbox driven by an impeller located centrally and axially and connected to the gearbox. Most specifically, the system utilizes pulse technology to improve weight transfer in horizontal wells by modulating flow, pressure and weight on the bit. The system can be used to overcome coiled tubing (CT) drill out challenges by overcoming friction forces that impede the downhole reach.
