Patent number: 11746924Abstract: Techniques for correlating changing hydraulic pressure differentials with interval control valve (ICV) movements are contemplated. In some aspects, the disclosed technology includes include methods for applying, by a surface controller, a series of differential pressure values to a hydraulic-open line, receiving, from a position sensor, a corresponding valve position for each of the differential pressure values, and calculating a lag time, a move speed and a response delay for each of the first series of differential pressure values. In some aspects, the method can further include steps for generating an ICV positioning model based at least in part on the lag time, the move speed, and the response delay calculated for each of the first series of differential pressure values. Systems and computer-readable media are also provided.Type: GrantFiled: September 17, 2019Date of Patent: September 5, 2023Assignee: HALLIBURTON ENERGY SERVICES, INC.Inventors: Ziquan Wang, Michael John Christie, Robert Joseph Smith, Aswin Balasubramanian

Patent number: 11668410Abstract: A method and system for determining a position of a linearly translating member. The method may comprise transmitting an excitation into a linearly translating member through one or more couplers from an acoustic device disposed in an outer housing, recording a reflected excitation from the linearly translating member with the acoustic device, and identifying a position of the linearly translating member with respect to the acoustic device. The system may comprise an outer housing, a linearly translating member disposed within the outer housing, an acoustic device disposed in the outer housing and configured to transmit an excitation at various frequencies and various amplitudes and record returned excitation frequencies and amplitudes and time of travel, and an information handling system in communication with the acoustic device.Type: GrantFiled: May 12, 2020Date of Patent: June 6, 2023Assignee: Halliburton Energy Services, Inc.Inventors: Joseph Chakkungal Joseph, Ravi Sharad Vayeda, Ziquan Wang, Paul Gregory James

Publication number: 20230136000Abstract: A method comprises monitoring a resistance over time of a tubing encased conductor (TEC) that electrically connects a first downhole gauge to a second downhole gauge positioned in a borehole deeper than the first downhole gauge. The method includes detecting that a first TEC fault has occurred in the TEC, in response to a change in the resistance being greater than a fault occurrence threshold and in response to an amount of the time of the change being smaller than a fault time threshold.Type: ApplicationFiled: April 24, 2020Publication date: May 4, 2023Inventor: Ziquan Wang

Publication number: 20220316322Abstract: This disclosure presents an apparatus to improve the position sensing of a moving mechanism, such as a fluid valve located within a borehole. The apparatus can utilize a light beam or an optical fiber to measure changes in the position sensor. The smaller and lighter apparatus can improve the accuracy of the sensing mechanism. In addition, three systems are presented. The first system utilizes a vibration sensor, such as a MEMS, and an accelerometer to calculate changes in the mechanism position of the moving mechanism. The second system utilizes a radiation source and detector combination, along with a moving radiation shield to provide more accurate position sensing than conventional techniques. In addition, a lens-based system is presented, that when combined with a radiation source, can calculate position information by detecting the diffusion or dispersal of the radiation against a radiation detector.Type: ApplicationFiled: June 9, 2022Publication date: October 6, 2022Inventors: Joseph Chakkungal Joseph, Ravi Sharad Vayeda, Ziquan Wang, Paul Gregory James

Patent number: 11293278Abstract: A system and method for identifying a position of a sliding sleeve. The system may comprise an outer housing, a sliding sleeve within the outer housing, one or more magnetic switches, and a magnet. A method may comprise closing a switch within a magnetic switch disposed with a magnet, wherein the magnetic switch is disposed downhole, and transmitting an electric current into a first electric branch, wherein the electric current traverses through first electric branch, through the magnetic switch, to a second electric branch, and to a node. The method may further comprise measuring the electric current or voltage at the node and identifying a position of a sliding sleeve in an outer housing from the measurement. The method may further comprise calibrating a linear resistor position sensor assembly based at least in part on the measurement.Type: GrantFiled: April 22, 2020Date of Patent: April 5, 2022Assignee: Halliburton Energy Services, Inc.Inventors: Joseph Chakkungal Joseph, Paul Gregory James, Ziquan Wang, Ravi Sharad Vayeda
