A tubewire buckling mitigation assembly for use with injection of tubewire into coiled tubing. The mitigation assembly includes a passageway having a small diameter passage, an intermediate diameter section and first and second tapered transition sections.

Tubewire injection buckling mitigation

A device for use with components for a downhole tool&#x2014;such as a throat, a nozzle, or a diffuser&#x2014;used for cleaning a wellbore, are disclosed which decreases the erosion of the components. The device may be comprised of a hardened material, such as stack of pure diamond disks brazed to form an insert for a throat. The device may also be comprised of polycrystalline diamond (PCD) washers stacked together and mechanically secured within the component such as a throat. The device may also be comprised of diamond grown on a mandrel into a trumpet shape, which may then be brazed or epoxied into the component. As each of these materials is harder than materials previously utilized, erosion performance is enhanced. A method of improving erosion performance of components utilized to clean a wellbore is also disclosed.

Downhole oilfield erosion protection by using diamond

Method and apparatus for running tubing into a lateral bore of a multilateral well, including a bottom hole assembly having at least one remotely activatable, radially deflectable toe, and preferably method and apparatus to laterally sweep the toe, signal when the toe fully kicks out and follow the toe into a lateral bore.
