Reducing Effects of Rig Noise on Telemetry

Abstract

Apparatus and methods for reducing effects of rig noise on telemetry. A method may include commencing operation of a telemetry system of a drilling rig and commencing operation of an equipment controller of the drilling rig. Commencing operation of the equipment controller may cause the equipment controller to automatically output control commands to automatically change operational parameters of the telemetry system and/or rig equipment of the drilling rig to reduce interference by rig noise with a telemetry signal.

Description

BACKGROUND OF THE DISCLOSURE[0001]Wells are generally drilled into the ground or ocean bed to recover natural deposits of oil, gas, and other materials that are trapped in subterranean rock formations. Well construction (e.g., drilling) operations may be performed at a wellsite by a well construction system (e.g., a drilling rig) having various surface and subterranean well construction equipment (e.g., rig equipment) operating in a coordinated manner. For example, a drive mechanism, such as a top drive located at a wellsite surface, can be utilized to rotate and advance a drill string into a subterranean rock formation to drill a wellbore. The drill string may include a plurality of drill pipes coupled together and terminating with a drill bit. Length of the drill string may be increased by adding additional drill pipes while depth of the wellbore increases. Drilling fluid may be pumped from the wellsite surface down through the drill string to the drill bit. The drilling fluid lub...

AI Technical Summary

Benefits of technology

[0005]The present disclosure introduces an apparatus including a telemetry system of a drilling rig and an equipment controller comprising a processor and a memory storing computer program code. The telemetry system includes a transmitter and a receiver. The transmitter is carried by a drill string and is operable to transmit a telemetry signal. The receiver is included in surface equipment of the drilling rig. The receiver is operable to generate an output signal including a telemetry signal signature, based on the telemetry signal, and a rig noise signature, based on rig noise generated by rig equipment of the drilling rig. The equipment controller is operable to automatically reduce interference by the rig noise with the telemetry signal by outputting control commands to change operational parameters of

Problems solved by technology

Efficiency of mud-pulse telemetry and electromagnetic telemetry is affected by noise generated by the well construction equipment (i.e., rig noise), which can interfere with telemetry signals communicated between the downhole transmitters and surface re
