Surface Depth and Time Recorder (SDR)

The Surface Depth and Time Recorder (SDR) is a rugged, intrinsically safe (IS) recorder for slickline and coiled tubing memory logging. It logs depth from a shaft encoder against time and can capture additional analog and frequency channels (e.g., tension, wellhead pressure, flowmeter). SDR provides real-time display of depth, time, cable speed, and tension, and supplies depth/time data for merging with memory tools. Two modes are available: Configuration and Logging.
