| 发明名称 | Method and system of an electromagnetic telemetry | ||
| 摘要 | An electromagnetic telemetry repeater. At least some of the illustrative embodiments are methods comprising inducing an electrical signal along a metallic tubular (the electrical signal carrying the information and the inducing within a borehole beneath the ocean floor), sensing an electric field proximate to the ocean floor, sensing a magnetic field proximate to the ocean floor, recreating the information using one sensed field as indicative of the information and the other sensed field as indicative of the noise, and sending the information toward the ocean surface. | ||

| 主权项 | 1. A method comprising: inducing an electrical signal along a metallic tubular, the electrical signal carrying information and the inducing being within a borehole beneath the ocean floor; sensing an electric field proximate to the ocean floor, the electric field associated with the electrical signal; sensing a magnetic field proximate to the ocean floor, the magnetic field associated with the electrical signal; recreating the information using one sensed field as indicative of the information, and the other sensed field as indicative of noise; and then sending the information toward the ocean surface. | ||
