Patent number: 10082942Abstract: A technique facilitates diagnosis of a telemetry system, such as a mud pulse telemetry system or an electro-magnetic telemetry system. The technique comprises operating a telemetry system in a wellbore and collecting a variety of data. The data may relate to a rig state, a downhole state, a signal state, a surface state, and/or other suitable types of data. The data is processed to determine whether states of operation indicated by the data match states indicating a problem with operation of the telemetry system. If a problem is detected, appropriate information regarding the problem is transmitted for use in correcting the problem.Type: GrantFiled: March 19, 2015Date of Patent: September 25, 2018Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Arnaud Jarrot, Sandra Reyes, Remi Hutin

Patent number: 8408330Abstract: Systems and methods cancel or compensate for an echo or noise in borehole communication. The systems and methods provide a downhole tool configured to provide borehole communication via mud pulse telemetry. The downhole tool pulses drilling fluid to generate a first pressure pulse and a second pressure pulse. The first pressure pulse moves upwardly with respect to the downhole component and is encoded with data associated a downhole measurement. A sensor is electrically connected to and in communication with the downhole tool. The first sensor is adapted to detect a characteristic of the second pressure pulse in the drilling mud. A ideal pressure pulse or a correction pressure pulse is generated by a downhole tool or a mud pulse modulator to reduce or cancel noise of the second pressure pulse.Type: GrantFiled: April 27, 2010Date of Patent: April 2, 2013Assignee: Schlumberger Technology CorporationInventors: Remi Hutin, Sandra Reyes, Shyam B.
