Sandia National Laboratories has developed a drilling diagnostic system with the goal of reducing the costs of geothermal well drilling. The system, known as Diagnostics While Drilling (DWD), transmits a variety of critical data from the drill bit location back to an operator at the surface over 5,000 feet of single conductor wireline. The team built a receiver to recover degraded signals from the DWD electronics at a rate of 800 kbps, which represents a four-fold increase over Sandia’s initial system.
