    摘要: A scale removal tool with adjustably positionable fluid dispensing arms. The scale removal tool may be configured for delivery to within a hydrocarbon well via coiled tubing. Thus, fluid may be driven through the coiled tubing and through the tool at the fluid dispensing arms. The fluid may thereby be jetted at high pressure toward scale at the wall of the well in order to achieve its removal. In the case of a well having scale of varying thicknesses, the fluid dispensing arms may be dynamically positioned and repositioned while downhole in the well, depending on scale thickness.

    摘要: A backpressure valve. The backpressure valve may be configured to maintain a substantially controlled pressure in coiled tubing uphole thereof while simultaneously being compatible with a ballistically actuated tool downhole thereof. The valve may include a housing with an uphole chamber in alignment with the coiled tubing and downhole chamber in alignment with the ballistically actuated tool. A gate mechanism disposed between the uphole and downhole chambers may thus be employed to receive a ballistic actuator from the uphole chamber for dispensing into the downhole chamber without sacrifice to pressure control within the coiled tubing.

    摘要: A technique utilizes a fishing tool that enables fishing operations for retrieval of well tools that may have a variety of sizes and configurations. The fishing tool is adjustable to enable selection of a desired size for engagement with a specific wellbore tool. The fishing tool is moved downhole to the well tool and engaged with the well tool. Once the fishing tool is engaged, the well tool can be retrieved to the surface.

Thus, fluid may be driven through the coiled tubing and through the tool at the fluid dispensing arms. The fluid may thereby be jetted at high pressure toward scale at the wall of the well in order to achieve its removal. In the case of a well having scale of varying thicknesses, the fluid dispensing arms may be dynamically positioned and repositioned while downhole in the well, depending on scale thickness. In this manner, the tool need not be removed from the well in order to reposition the fluid dispensing arms for optimum scale removal at each section of the well. As such, considerable time and expense of a scale removal application may be saved.
