A method and assembly for accurately positioning and safely deploying a packer and at least one tool, such as a perforating gun(s), in a subterranean well during a one-trip completion operation. The assembly comprises an expandable packer, a location device(s), such as a gamma ray probe and/or a collar locator, and at least one tool, such as a perforating gun and/or formation logging tool. The assembly is lowered into a subterranean well on electric line and the packer is accurately positioned in the well by means of the location device(s), and thereafter, is expanded. The remaining assembly is automatically released from the expanded packer and accurately repositioned to a new location within the tubular by means of the electric line and location device(s). The tool is then activated to perform the desired operation, and thereafter, the assembly is removed from the well.
