Abstract: A method and apparatus is provided for hermetic sealing of a wireline and a termination housing. The primary electrical connection of a wireline termination is sealed within a fluid-filed packoff bore of a termination housing. Wireline release strength can be selected upon wireline connection. A sealed termination housing has an uphole mechanical structure or support for transferring wireline armor tensile loads to the sub, a packoff bore for housing the wireline electrical conductor at a primary electrical connection, and a downhole closure. An inherent leak path of pressurized well fluids into termination housing is blocked by a dielectric fluid pad therein that fills the packoff bore from the downhole closure end and to a location at or uphole of the electrical connection made between the wireline and a hermetically sealed electrical connection exiting the downhole closure.

Abstract: Described are various embodiments of a coiled tubing bottom hole assembly system adapted for insertion into a borehole and determining parameters of interest within the borehole. The bottom hole assembly comprises a pressure sensor array for providing differential pressure measurements across the milling assembly, at least one accelerometer for providing acceleration measurements near the bottom hole assembly indicative of at least one of vibration, bit condition, rotational speed and translational parameters and a sensor assembly for providing a measurement of weight-on-bit and applied torque. A data processor adapted to receive inputs from the pressure sensor array, the at least one accelerometer and the sensor assembly.
