Publication number: 20240011377Abstract: Aspects of the subject technology relate to systems, methods, and computer-readable media for detecting and marking events that occur during a fracturing operation. Data related to performance of a fracturing operation in a wellbore during performance of a stage of the fracturing operation can be accessed. An event detection algorithm for detecting a specific event during the fracturing operation can be accessed. The event detection algorithm can be applied to the data to determine whether the specific event actually occurs during at least a portion of the stage of the fracturing operation. As follows, an indication of the specific event occurring during the stage of the fracturing operation can generated if it is determined that the specific event actually occurred during the at least a portion of the stage of the fracturing operation.Type: ApplicationFiled: July 7, 2022Publication date: January 11, 2024Applicant: Halliburton Energy Services, Inc.Inventors: Ubong Akpan INYANG, Dinesh Ananda SHETTY, Jie BAI, Srividhya SRIDHAR

Publication number: 20230383639Abstract: This disclosure presents processes for mitigating wellbore screen-out. The processes can automatically determine an onset of wellbore screen-out by analyzing corrected pressure data from the at least one pressure sensor, select at least one type of mitigation action based on the automatic determination of the onset of the wellbore screen-out, and mitigate the wellbore screen-out with the selected at least one type of mitigation action.Type: ApplicationFiled: May 26, 2022Publication date: November 30, 2023Inventors: Srividhya Sridhar, Joseph Andrew Romani, Dinesh Ananda Shetty

Patent number: 11753917Abstract: When a child well is hydraulically fractured near the depleted reservoir volume surrounding a previously produced parent well, it is economically efficient to deliver proppant to the formation volume and fractures not reached by the parent well. A fracture length, which is the distance fluid travels from the child well to the depleted region, is calculated as a function of fracture stage. From identified trends in fracture length, fracture length for future stages can be predicted. Based on predicted fracture length, the slurry or treatment volume to cause well interference can be estimated. Proppant concentration or fracturing stage design can be adjusted so that the well interference volume is larger than the treatment volume and proppant is efficiently delivered to the child well fractures.Type: GrantFiled: September 25, 2020Date of Patent: September 12, 2023Assignee: Halliburton Energy Services, Inc.Inventors: Dinesh Ananda Shetty, William Owen Alexander Ruhle, Srividhya Sridhar

Patent number: 11619126Abstract: A process to determine whether a leak-off event is occurring during the treatment stage of an active borehole. The leak-off event data, such as the severity or magnitude of the potential leak-off, can be communicated to other systems to adjust the treatment stage, the fluid composition, the fluid pressure, or the fluid flow rate. Diverter material can be added to the fluid. The monitoring of the leak-off event can occur over a time interval, such as the time of the treatment stage and periodic adjustments to the treatment stage can be implemented. The leak-off event can be identified when a fluid pressure slope indicates an overall increase in pressure in an adjacent borehole or if the amount of fluid entering an adjacent borehole exceeds a leak-off threshold.Type: GrantFiled: December 4, 2020Date of Patent: April 4, 2023Assignee: Halliburton Energy Services, Inc.Inventors: William Owen Alexander Ruhle, Dinesh Ananda Shetty, Srividhya Sridhar, Shahab Jamali

Patent number: 11598273Abstract: A system comprising engine driven pumps, control units, a rate control algorithm, and a trained algorithmic model. The control units store operation variables for the engine driven pumps. The rate control algorithm includes an instruction set to read the operation variables for the engine driven pumps. The instruction set comprises a trained algorithmic model with a parameter space based on historical operation variables. The trained algorithmic model determines an optimal distribution rate based on an objective. The instruction set generates rate control variables based on the determined optimal distribution rate. Each rate control variable comprises a selected control unit identifier and a rate value. The instruction set distributes each rate control variable based on the selected control unit identifier. The trained algorithmic model determine the optimal distribution rate using an objective that defines a desired mixture between a first fuel and a second fuel.Type: GrantFiled: June 17, 2021Date of Patent: March 7, 2023Assignee: HALLIBURTON ENERGY SERVICES, INC.Inventors: Srividhya Sridhar, Jie Bai, Ubong Akpan Inyang

Publication number: 20230030531Abstract: Systems and methods of the present disclosure generally relate to monitoring, evaluating, and controlling fracture geometry during a hydraulic fracturing operation, in real time. A method comprises measuring a signal representing a condition in a wellbore; inputting the signal into a model for estimating a dimension of a dominant fracture; determining the dimension of the dominant fracture; determining a target dimension for the dominant fracture; and minimizing a difference between the dimension of the dominant fracture and the target dimension in real time, by adjusting at least an injection pressure or flow rate of a hydraulic fracturing fluid into the wellbore.Type: ApplicationFiled: October 12, 2022Publication date: February 2, 2023Applicant: Halliburton Energy Services, Inc.Inventors: Dinesh Ananda Shetty, Xusong Wang, Xiang Wu, Srividhya Sridhar

Publication number: 20230009947Abstract: A system and method to predict or detect screen outs by measuring pressure conditions in the well in real-time, and that conducts mitigation of the condition. Pressure responses of the well are detected during a fracture operation. The system processes the pressure responses by removing the effects of non-screen out related factors. A mathematical model is applied to the pressure responses to detect or predict the screen out. In response to the screen out detection or prediction, corrective action may be initiated.Type: ApplicationFiled: July 9, 2021Publication date: January 12, 2023Inventors: William Ruhle, Dinesh Ananda Shetty, Srividhya Sridhar
