Abstract
A receiver for a dual telemetry measurement while drilling (MWD) system and method for operating same are provided. The receiver includes a mud pulse receiver module for receiving a first signal sent using mud pulse telemetry via a pressure transducer configured to detect mud pulses transmitted through a mud column in a drill string; an electromagnetic (EM) receiver module for receiving a second signal sent using EM telemetry via the drill string and a formation; and a processer for obtaining the first signal when operating in a mud pulse mode and the second signal when operating in an EM mode and having MWD data displayed at a surface system.
Claims20
A receiver for a dual telemetry measurement while drilling (MWD) system, the receiver comprising:
- a mud pulse receiver module for receiving a first signal sent using mud pulse telemetry via a pressure transducer configured to detect mud pulses transmitted through a mud column in a drill string;
- an electromagnetic (EM) receiver module for receiving a second signal sent using EM telemetry via the drill string and a formation;
- at least one interface connecting the mud pulse and EM receiver modules into the receiver to collect data via both mud pulse and EM telemetry;
- and
- a processer for selectively obtaining the first signal when operating in a mud pulse mode and the second signal when operating in an EM mode and having corresponding MWD data displayed at a surface system.
A method of receiving data at a receiver for a dual telemetry measurement while drilling (MWD) system, the method comprising:
- when operating in a mud pulse mode, receiving, at a mud pulse receiver module, a first signal sent using mud pulse telemetry via a pressure transducer configured to detect mud pulses transmitted through a mud column in a drill string;
- when operating in an electromagnetic (EM) mode, receiving, at an EM, receiver module, a second signal sent using EM telemetry via the drill string and a formation;
- collecting data via either the mud pulse receiver module or the EM receiver module using at least one interface connecting the mud pulse and EM receiver modules into the receiver;
- selectively obtaining, at a processor, the first signal when operating in the mud pulse mode and the second signal when operating in the EM mode;
- and
- enabling corresponding MWD data to be displayed at a surface system.
