Patent number: 12215586Abstract: A spindle with a mechanism for transferring axial force from an inner drive assembly to an outer drive assembly. The spindle's inner drive shaft is connected to an inner member of a dual-rod pipe by a drive rod having a sliding sleeve. The sleeve is fixed rotationally with the drive shaft, but not axially. When axial force drives the drive rod toward the drive member of the spindle, the sleeve contacts a stop member which is paired to the outer drive assembly. The stop member may be a pair of dowel pins. Axial force is thereby transferred from the inner member to the outer member, allowing such forces to be absorbed by the outer member's larger drive components.Type: GrantFiled: June 26, 2023Date of Patent: February 4, 2025Assignee: The Charles Machine Works, Inc.Inventor: Max A.

Patent number: 12215567Abstract: An activation control module utilizes gravity and/or centrifugal acceleration to move a mechanical element that controls, activates or deactivates a mechanical or hydraulic mechanism, for use with a downhole tool such as a drilling tool or reamer in a wellbore. In embodiments, the activation control module described herein may utilize a combination of centrifugal acceleration and/or gravity due to an inclination of the downhole tool to move a valve, which turns off pressure to a hydro-mechanical system. The activation control modules may be utilized in applications where very little space is available for larger mechanisms. Further, the activation control modules do not require expensive and complex electro-mechanical systems, reducing or eliminating the need for batteries, wiring, electronics, motors, pumps and the like. Moreover, the activation control modules described herein do not require the use of a turbine, a centrifugal clutch or a linear actuator.Type: GrantFiled: August 16, 2023Date of Patent: February 4, 2025Assignee: Halliburton Energy Services, Inc.Inventors: Van Jordan Brackin, Jacob H.

There can also be a second force member to exert a second force in the first direction for more variability of the cutting profile in the first direction and a third force member to exert a third force in an opposite second direction.Type: GrantFiled: September 25, 2022Date of Patent: January 23, 2024Assignees: CNPC USA Corporation, Beijing Huamei, Inc.

Patent number: 11808090Abstract: The force modulation system for a drill bit includes a cutter, a holder, a holder retention device, and a first force member. The cutter fits in the holder, and the holder fits in the drill bit. The holder retention device exerts a holder retention force in a first direction. The first force member exerts a first force in a second direction. The second direction is angled offset to the first direction so as that the cutting profile of the force modulation system is now variable in the second direction, according to the first force. There can also be a second force member to exert a second force in the first direction for more variability of the cutting profile in the first direction. The second force member can be made integral with the first force member.Type: GrantFiled: September 25, 2022Date of Patent: November 7, 2023Assignees: CNPC USA Corporation, Beijing Huamei Inc.

Patent number: 11761298Abstract: A location of a cut and an amount of force to be used in a pull operation for a plug & abandonment (P&A) operation can be determined. Measurements of at least one characteristic of fluids and solids disposed in an annulus defined between a casing and a wall of a wellbore can be received. A total fluid and solid friction force drag can be determined using hydrostatic force that is determined from the measurements. A mechanical friction force drag can be determined based on a weight of the casing. The mechanical friction force drag and the total fluid and solid friction force drag can be used to determine a friction factor. The friction factor can be used to determine a depth location at which to cut the casing and a pull force for pulling the casing from the wellbore in the P&A operation.Type: GrantFiled: August 30, 2021Date of Patent: September 19, 2023Assignee: Landmark Graphics CorporationInventors: Robello Samuel, William Wade Samec, Roddy Hebert, Robert H.

Patent number: 11739253Abstract: Proteinaceous enhanced oil recovery operates on the principle that proteins can be denatured using chemicals to break them down into a viscous polymeric mixture that exhibits an EOR effect. In one or more embodiments, the proteins in question are sourced from an algae (spirulina) meal, which could be obtained as a waste product from wastewater treatment or bioprocessing operations, including biofuel production where the lipids are extracted for fuel but the large volumes of proteins are considered a waste material with little or negative value. In other embodiments, other biomasses are used, especially edible biomasses, thereby mitigating public resistance to drilling operations due to concerns of perceived toxicity of chemicals. This also mitigates legal liability from the use of chemicals that are known to be toxic. Additionally, the agents are denatured biomasses that have not undergone expensive purification or separation steps. This will make these agents highly cost competitive.Type: GrantFiled: September 4, 2020Date of Patent: August 29, 2023Assignee: University of Louisiana at LafayetteInventors: William Chirdon, Peter Schexnayder, Garrett Thibodeaux, Nicholas Baudoin
