Abstract
Memory tool deployment method, system, and apparatus include a landing ring fit on a pipe deployed in a well. A drop-off tool has a landing collar and has a tool string with one or more memory tools. The drop-off tool is connected to a wireline and is deployed through the pipe in the well with the wireline. The drop-off tool is landed on the landing ring on the pipe so that the memory tools extend beyond the pipe. The wireline is released from the drop-off tool and is removed from the pipe so that logging operations can be performed. After logging, the wireline is redeployed in the pipe in the well and is reconnected to the drop-off tool to retrieve the memory tools from the pipe.
