    摘要: A down-hole assembly used to locate an existing window in a main cased well bore and guide equipment through the window and into a lateral well bore after removal of a whip stock. The assembly includes a running tool with a convex section detachably connected to a concave section of a guide member. The running tool includes a window locator that locates the window. The guide member includes an inclined or wedge shaped portion for guiding tools or equipment through the window and into the lateral well bore so that remedial work can be carried out.

    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.

    摘要: An apparatus is disclosed as having a downhole string component having first and second ends. The first end has first and second signal couplers, and the second end has third and fourth signal couplers. An electrical conductor is in electrical communication with the first, second, third, and fourth signal couplers. The first and third signal couplers have a first band pass filter with a first resonant frequency and the second and fourth signal couplers have a second band pass filter with a second resonant frequency.

    摘要: A technique that is usable with a subterranean well that has a first string that lines a borehole includes running a second string into the well and engaging a deflecting face of a deflector to deflect the second string into a window of the first string. The technique includes performing at least one of positioning the second string and orienting the second string using a profile on the deflector downhole of the deflecting face.
