  • Patent number: 12215586
    Abstract: 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.

  • Patent number: 12215567
    Abstract: 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.

  • Patent number: 12078052
    Abstract: The disclosure presents processes to determine the direction and magnitude of tubing eccentricity along the length of a tube inserted within a borehole. The tubing can be a wireline, a drill string, a drill pipe, or tubing capable of allowing fluid or other material to flow through it. As borehole operations proceed, the tubing can move toward the side of the borehole. This eccentricity can cause excess wear and tear on the tubing, on the casing of the borehole, or on the inner surface of the subterranean formation. The eccentricity can be measured using acoustic signals that are collected downhole covering the azimuthal angles 0° to 360° at a location in the borehole. The collected signals can be filtered, transformed, and analyzed to estimate the tubing eccentricity. Other processes and systems can use the results to obtain cement bond evaluations through tubing and to determine preventative or restorative actions.

The torsional impact assembly includes an upper end cover, a reversing switch, a pendulum, a lower shell, a lower end cover, a nozzle, a connecting block and a retaining ring. The high-frequency axial impact assembly converts the flowing drilling fluid into a pulsed jet to achieve a high-frequency axial impact. The torsional impact assembly enables a torsional impact through a shunt, and finally enables a high-frequency composite impact, which can effectively reduce the stick-slip of the drill string, jump drilling and other downhole accidents. By reducing the friction between the drill string and the borehole wall, the impactor can reduce WOB loss, increase the ROP, and improve the drilling efficiency.

  • Patent number: 11879296
    Abstract: The force modulation system for a drill bit includes a cutter, a blade cap, a cap retention device, and a first force member. The cutter or cutters fit in the blade cap, and the blade cap fits to the drill bit. The cap retention device exerts a cap retention force in a first direction. The first force member exerts a first force in a second direction. The cutting profile of the force modulation system is now variable in more than one direction so as to avoid excessive forces from more than one direction for each cutter on the blade cap. 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.

  • Patent number: 11761298
    Abstract: 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.

  • Patent number: 11739253
    Abstract: 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.
