Patent number: 11149544Abstract: A technique facilitates communication in a subsea well application. The technique involves deployment of a blowout preventer subsea control and telemetry system to a subsea location proximate a wellbore. The blowout preventer subsea control and telemetry system is coupled to both a blowout preventer system and a wireless telemetry system. The wireless telemetry system has a plurality of repeaters deployed along the wellbore. The blowout preventer subsea control and telemetry system is used both to collect data from the wireless telemetry system and to control operation of the blowout preventer system. For example, the blowout preventer subsea control and telemetry system may receive control signals from a surface system and also relay data to the surface system through a common communication line.Type: GrantFiled: December 19, 2016Date of Patent: October 19, 2021Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Benoit Deville, Arnaud Croux, Stephane Vannuffelen

Publication number: 20210274270Abstract: A method for transmitting signals in a subsea environment includes determining that a quality of an acoustic signal is below a threshold. The acoustic signal travels from a first device, through water in the subsea environment, to a second device. A parameter of the first device, the second device, or both is then adjusted to improve the quality of the acoustic signal when the quality of the acoustic signal is below the threshold.Type: ApplicationFiled: May 17, 2021Publication date: September 2, 2021Inventors: Arnaud Jarrot, Julius Kusuma, Andriy Gelman, Arnaud Croux, Sudhir Pai, Neil Herbst, Jack Vincent

Patent number: 10711601Abstract: A system and method to automate data acquisition in a wireless telemetry network optimizes data acquisition to best match a target data set that the user desires given the performance limitations of the telemetry network. The user defines the target data set by providing inputs regarding a target quality of the target data set relative to a data set that has been produced and stored by a communication node in the network. The performance limitations of the network are defined in a system operating envelope. A data acquisition cycle is then automatically initiated and propagated in the network to acquire an actual data set that is an optimal match for the user's target given the system operating envelope.Type: GrantFiled: June 28, 2019Date of Patent: July 14, 2020Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Sukru Sarac, Clement Probel, Stephane Vannuffelen, Andriy Gelman, Arnaud Croux, Elias Temer, Khaled Mouffok

Patent number: 10708869Abstract: An acoustic network is located in a formation traversed by a borehole having a pipe contained therein. The acoustic network includes a backbone network having a number of backbone modems engaging the pipe and acoustically communicating along the pipe using a first modulation technique. A number of end node modems acoustically communicate using a second modulation technique orthogonal to the first modulation technique. At least one of the backbone modems is a bridge hub modem that is coupled to both the backbone network and an end node modem and communicates with the backbone network using the first modulation technique and with the end node modem using the second modulation technique. The end node modems may have a hibernation mode defined by low energy usage with no transmission or receipt of data, and a transmission mode defined by transmission of data by the end node modem.Type: GrantFiled: January 30, 2017Date of Patent: July 7, 2020Assignee: Schlumberger Technology CorporationInventors: Arnaud Croux, Julius Kusuma, Stephane Vannuffelen

Publication number: 20200141229Abstract: A network management technique for an acoustic communication system made up of a network of communication nodes is disclosed. Various of the nodes that are located intermediate a source node and a receiving node can detect communication failures in the network and then take action to efficiently recover from the failure, rather than acting only as repeaters. By allowing intermediate nodes to participate in recovery decisions, the speed and the quantity of real-time information transmission in the network can be improved.Type: ApplicationFiled: July 12, 2018Publication date: May 7, 2020Inventors: Arnaud Croux, Julius Kusuma
