Patent number: 11659307Abstract: 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: GrantFiled: May 17, 2021Date of Patent: May 23, 2023Assignee: ONESUBSEA IP UK LIMITEDInventors: Arnaud Jarrot, Julius Kusuma, Andriy Gelman, Arnaud Croux, Sudhir Pai, Neil Herbst, Jack Vincent

Patent number: 10976185Abstract: Sensor array noise reduction is provided. Techniques involve systems and methods for reducing sensor array noise by estimating an instantaneous frequency of a coherent noise signal in a logging system. The instantaneous frequency may be estimated based on a rotation of an electric motor in the logging system, or may estimated by applying suitable signal processing algorithms on measurements in the logging system. A virtual measurement may be computed using the instantaneous frequency. The virtual measurement may be demodulated to obtain a baseband signal, and noise may be removed from the baseband signal to obtain a denoised signal.Type: GrantFiled: June 12, 2017Date of Patent: April 13, 2021Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Arnaud Jarrot, Julius Kusuma

Patent number: 10540758Abstract: Image feature alignment is provided. In some implementations, a computer-readable tangible medium includes instructions that direct a processor to access a reference feature point associated with a high contrast region in a first sub-image that is associated with a first section of a borehole. Instructions are also present that direct the processor to identify several candidate feature points in a second sub-image associated with a second section of the borehole adjacent to the first section of the borehole, with each of the candidate feature points being believed to possibly be associated with the high contrast region. Additional instructions are present that direct the processor to prune the candidate feature points using global solution pruning to arrive at a matching candidate feature point in the second sub-image.Type: GrantFiled: November 13, 2015Date of Patent: January 21, 2020Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Andriy Gelman, Arnaud Jarrot, Robert Laronga

Patent number: 10539008Abstract: Systems and methods are provided for estimating the tool center position of a downhole tool, the geometry of the borehole, and/or a mud parameter based on sensor measurements from the downhole tool, even when the downhole tool center is moving over time. At least one sensor may obtain a set of measurements that relates to distance-to-borehole in a borehole at a number of azimuths. A processor may estimate a set of values defining borehole boundary and a set of positions of a center of the downhole tool in the borehole, at least in part by estimating the borehole boundary based on the set of measurements assuming a previously estimated position of the center of the downhole tool is true and estimating the position of the center of the downhole tool based on the set of measurements assuming a previously estimated borehole boundary is true, and iterating at least until convergence.Type: GrantFiled: September 21, 2016Date of Patent: January 21, 2020Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Arnaud Jarrot, Emmanuel Legendre

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
