DR - Connect
Dual Telemetry System

DR-Connect is a dual telemetry system, combining our DR-EEM and our DR-Shockwave systems into one compatible unit. We utilize a non-magnetic UBHO in the middle to reduce any interference on the sensors. During drilling, the EM signal from the DR-EEM tool is being used for all surveying and gamma information. Should the EM signal be impeded by formation resistivity, we can easily switch over to mud pulse telemetry on the fly. We maintain partial retrievability and optimal signal strength by keeping the pulse tool above our EM package. It is a low-cost solution for areas with questionable EM signal reliability.
