Patent number: 11767737Abstract: Disclosed herein are compositions and methods for reducing fluid loss in a well bore, methods for wellbore strengthening and increasing the integrity of the borehole of an oil or gas well. Also disclosed are methods for artificially increasing the temperature of a subsurface formation in the wellbore to increase the apparent wellbore strength. The mechanism for accomplishing this revolves around increasing fracture propagation pressure by actively manipulating thermal wellbore stresses.Type: GrantFiled: August 28, 2020Date of Patent: September 26, 2023Assignee: BOARD OF REGENTS, THE UNIVERSITY OF TEXAS SYSTEMInventors: Eric Van Oort, Besmir B.

Patent number: 11466554Abstract: Embodiments are directed to managing and improving a drilling and completions process at a hydrocarbon extraction site, and to optimizing resource allocation at a hydrocarbon extraction site/region. In one scenario, a computer system accesses data generated by hardware sensors implemented by drilling and completion equipment at a hydrocarbon extraction site. The computer system formats the sensor data into a form readable by a data mining algorithm, and mines the formatted sensor data to identify characteristics related to the drilling and completion process. The computer system also accesses and integrates historical data related to the drilling and completion equipment at the hydrocarbon extraction site. The computer system then computes drilling and completion performance indicators that identify inefficiencies based on the characteristics identified for the equipment and based on the accessed historical data. Then, a remediation step is performed to resolve the identified inefficiency.Type: GrantFiled: March 20, 2019Date of Patent: October 11, 2022Assignee: QRI GROUP, LLCInventors: Ali Karimi Vajargah, David Castineira, Zheren Ma, Cedric Gael Fraces Gasmi, Hamed Darabi

Patent number: 10991193Abstract: A vending machine for dispensing heated granular foodstuffs includes a receptacle dispensing assembly for dispensing a receptacle into a receiving zone. A cooled storage hopper stores granular foodstuffs, and has an open bottom end. A discharge assembly is in communication with the open bottom end for transporting the quantity of the granular foodstuffs away from the cooled storage hopper. A heating assembly receives the quantity of the granular foodstuffs from the discharge assembly, heats the quantity of the granular foodstuffs with a heating fluid, and dispenses the quantity of the granular foodstuffs into the receptacle in the receiving zone. A heating fluid generator supplies heating fluid to the heating assembly. A condiment dispenser dispenses at least one condiment into the receptacle in the receiving zone.Type: GrantFiled: March 22, 2019Date of Patent: April 27, 2021Inventor: Ali Karimi-Shirazia
