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.

Abstract: An apparatus, method, and system for generating pressure pulses in a drilling fluid flowing within coiled tubing assembly is described that includes; a flow throttling device longitudinally and axially positioned within the center of a main valve actuator assembly that allows main exit flow fluid to flow past a drive shaft and motor such that the pilot fluid and the main exit flow fluid causes one or more flow throttling devices to generate large, rapid controllable pulses. The pulses generated by the flow throttling device thereby allow transmission of well-developed signals easily distinguished from any noise resulting from other vibrations due to nearby equipment within the borehole or exterior to the borehole, or within the coiled tubing assembly wherein the signals also provide predetermined height, width and shape of the signals.

Abstract: An apparatus and system for generating pressure pulses for enhancing and completing a well bore within a coiled tubing assembly including: a CT-MWD-FTD tool longitudinally and axially positioned within the center of a main valve assembly including a main valve. The drilling fluid is subsequently split into both an inlet main fluid stream and a pilot fluid stream, wherein the pilot fluid stream subsequently flows such that the pilot fluid recombines with the main flow stream to become a main exit fluid flow. The main exit fluid flow then proceeds toward a motor housing wherein one or more annular pressure sensors measure the pressure of fluid flow with sensors that send signals to a Digital Signal Processor (DSP) that controls flow throttling devices which generate controllable, large, rapid and measurable energy pulses.

Abstract: An apparatus, method, and system described for generating pressure pulses in drilling fluid utilizing a flow throttling device which includes a controllable pulser operating sequentially within a downhole assembly within a drill string of a drill pipe. The system includes drilling fluid, fluid flow, and fluid drilling pump which when combined creates fluid flow into a bore pipe annulus within the downhole assembly creating a base line bore pipe pressure wherein bore pipe pressure is sensed via a sensor and information is sent to a Digital Signal Processor (DSP) that interprets the information. The DSP also receives information from an annulus pressure sensor that senses drilling fluid pressure as it returns to the pump. The DSP recognizes pressure variation input from the annulus pressure sensor and bore pipe pressure sensor and detects pressure variation providing signals as data information to the DSP, determining required action to adjust pulser operation.
