Embodiment Construction

[0027] Throughout the following description, specific details are set forth in order to provide a thorough understanding to those skilled in the art. However, well known elements may not have been shown or described in detail to avoid unnecessarily obscuring the disclosure. The following description of examples of the present technology is not intended to be exhaustive or to limit the system to any precise form of example implementation. Accordingly, the specification and drawings are to be regarded in an illustrative rather than a restrictive sense.

[0028] figure 1 An example drill operation is schematically shown. The drill rig 10 drives a drill string 12 comprising a section of drill pipe extending through the borehole 11 to a drill bit 14 . The illustrated drilling rig 10 includes a derrick 10A for supporting a drill string, a drill floor 10 and a drawworks 10C.

[0029] The diameter of the drill bit 14 is larger than the diameter of the drill string above the drill ...

Abstract

An active downhole antenna located in a borehole receives electromagnetic (EM) telemetry transmissions from sources in adjacent boreholes. The antenna comprises a processor operable do decode and measure signal to noise ratio of received transmissions. Data received at the active antenna is transmitted to surface using a high-speed data communication network. The active antenna may handle data communications from multiple downhole EM telemetry transmitters.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Patent Application Serial No. 62 / 440618, filed December 30, 2016. As far as the United States is concerned, this application claims the benefit under 35 U.S.C §119 of U.S. Patent Application No. 62 / 440618, filed December 30, 2016, entitled "SYSTEM ANDMETHOD FOR DATA TELEMETRY AMONG ADJACENT BOREHOLES," which The US Patent Application is hereby incorporated by reference for all purposes. technical field [0003] This application relates to subsurface drilling, in particular to data telemetry. Embodiments provide systems and methods for transferring information, such as logging information, measurement-while-drilling information, between downhole tools and surface equipment. Embodiments are applicable to the drilling of oil and gas recovery. Background technique [0004] Recovering oil and gas from subterranean areas often involves drilling wellbores. [0005] The borehole is ma...
