A wireline extension assembly comprises a first tubing string housing a wireline extension electrically interconnecting wet connects at the upper and lower ends of the first string, with the lower wet connect being electrically connected to a downhole tool. The assembly is pushed into the horizontal leg of a deviated wellbore by forming a second tubing string extending upward from the upper end of the first string, thereby positioning the tool within the horizontal leg while leaving the upper wet connect disposed within the vertical leg. A primary wireline is then run from a surface wireline unit into the upper string and connected to the upper wet connect, thus providing electrical power, data communication, and/or other facilities to the tool. The tool can be repositioned within the horizontal leg by withdrawing the primary wireline, removing or upper string tubing sections, and then reinstalling the primary wireline.
