Abstract: Wireline plugs for use in a Y-tool. In some embodiments, the wireline plug can include an elongated body defining a bore therethrough. A first end of the elongated body can include an outer surface configured to serve as a fishing neck and a second end configured to connect to a downhole tool. The wireline plug can include an elongated seal defining a bore therethrough disposed within a portion of the bore defined by the elongated body. The elongated seal can be configured to provide an at least partial fluid seal between an inner surface of the bore defined by the elongated body and an outer surface of a wireline when disposed within the bore defined by the elongated seal. The elongated seal can be formed from a polymer, an elastomer, or a combination of a polymer and an elastomer.

Abstract: Anchor assemblies for use on a downhole cable and processes for using same. In some embodiments, the anchor assembly can include a first anchor configured to be releasably connected to a second anchor. The first anchor can define a bore therethrough that can be configured to receive and permit a cable to move therethrough such that the cable can be connected to the second anchor. The second anchor can include one or more switchable magnets each configured to switch between a non-magnetized state and a magnetized state. When the anchor assembly is located within a downhole casing and the one or more switchable magnets are switched from the non-magnetized state to the magnetized state, the one or more switchable magnets can be configured to secure the second anchor to an inner surface of the downhole casing.
