Patent number: 11934180Abstract: A method of controlling a pumping sequence of a fracturing fleet at a wellsite. A managing application executing on a computer in the control van can retrieve the pumping sequence from a local or remote storage computer. The managing application can establish an electronic communication link to receive sensor data from a plurality of fracturing units. The managing application can control the plurality of fracturing units with a stage script with multiple sequential instructions for a pumping stage of a pumping sequence while receiving one or more periodic data sets from the plurality of fracturing units wherein the data sets are indicative of the current state of the pumping stage of the pumping sequence.Type: GrantFiled: May 2, 2023Date of Patent: March 19, 2024Assignee: Halliburton Energy Services, Inc.Inventors: Mikko Jaaskelainen, Joshua Lane Camp, Ian Bradford Mitchell

Publication number: 20230297672Abstract: A method is disclosed which comprises accessing a detector model that is trained in parallel with an operator model and an attacker model using a reinforcement learning technique based on iteratively simulating scenarios of operation of an environment to generate training data and learning weights of the models based on the simulated training data. The simulating of a scenario is based on the last learned weights of the models. The method further comprises, during operation of the environment, applying the detector model to an operator action, a prior observation of state of the environment from prior to taking the operator action, and a current observation of the environment from after taking the operator action, to detect whether an attack on the environment has occurred.Type: ApplicationFiled: December 27, 2022Publication date: September 21, 2023Inventors: Jean-Paul Watson, Alyson Lindsey Fox, Sarah Camille Mousley Mackay, Wayne Bradford Mitchell, Matthew Landen, Key-Whan Chung, Elizabeth Diane Reed

Patent number: 10073222Abstract: Aspects of the disclosure include an optical fiber sensing system and apparatus that provide for free rotation of fiber optic cables containing multiple cores. For example, the disclosure presents a fiber optic rotary joint, comprising a stator housing a non-rotating portion of a dual-core fiber optic cable and a rotor housing a rotating portion of the dual-core fiber optic cable. In such an example, the rotor is mounted to the stator to allow rotation of at least a portion of the rotor about at least a portion of the stator. Further provided is an optical fiber sensing system, comprising one or more multiplexor/demultiplexors configured to multiplex and demultiplex one or more signals, a dual-core fiber optic cable communicatively coupled to the multiplexor/demultiplexor and configured to carry one or more signals on an inner core and an outer core disposed about the inner core, and a dual-core fiber optic rotary joint.Type: GrantFiled: November 15, 2013Date of Patent: September 11, 2018Assignee: Halliburton Energy Services, Inc.Inventors: Mikko Jaaskelainen, Ian Bradford Mitchell
