Book Description
A description is given of the Raytheon Downhole Information System (RDIS), a real time electromagnetic borehole measurements while drilling system, applicable to oil, gas, and geothermal drilling. It communicates in both directions through the earth in a single hop at a downlink data rate of 3 bps and uplink rates dependent on depth--typically 6 bits/second at 10,000 ft and 2 bits/second at 15,000 ft; electromagnetic signal transmission time of approximately .1 second. Downhole hardware for communications, sensors, and power are packaged in three 30 ft subs. Downhole hardware can be developed to permit operation in a 275°C geothermal environment. A cost analysis is included that predicts RDIS service could be economically priced at approximately $1000/day. Commercial availability depends primarily on proof of capability by demonstration in a working drilling well. The most significant portions of needed hardware are available. A description of a geothermal drilling telemetry system is included in Appendix A.

Book Description
This book explains the theory, numerical modeling, and applications of a borehole electromagnetic telemetry system used for wireless communication between the downhole tool and the surface control center during oilfield drilling. The authors begin by introducing borehole electromagnetic telemetry and explaining each part of the system with schematics and illustrations. They describe the working principle and compare it with other borehole wireless communication methods, such as mud pulse telemetry. They then address 2D and 3D electromagnetic telemetry modelling, listing previous 2D and 3D modeling methods and detailing the advantages and limitations, before discussing their recent work on a novel layered finite element method for 2D electromagnetic telemetry modelling, and on 3D electromagnetic modelling based on integral equation, thin wire kernel, and layered medium Green’s functions. Lastly, the authors show applications of electromagnetic telemetry, including single well borehole wireless communication and cross well communication in pad drilling. This includes photos, figures, and field data from real oilfield jobs. This book is a useful reference for drilling engineers, well logging tool research and development scientists and researchers, as well as for students in the areas of petroleum engineering and electrical engineering.
