  • 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: 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.

  • Patent number: 11255144
    Abstract: Disclosed herein are various embodiments of methods and systems for drilling an oil or gas well safely and efficiently using underbalanced or near-balanced drilling techniques, wherein the primary means of pressure control is a Annular Pressure Control Diverter positioned below the BOP stack, with a return flow pattern where no drilling fluid returns up the (traditional) annulus between the drill pipe and the production casing and instead drilling fluid returns up the annulus between the production casing and intermediate casing. Drilling fluid returns flow through a wellhead, instead of a flow spool conventionally located below an upper RCD, and hence to the drilling choke. This drilling approach eliminates the need for hydraulic fracturing and preserves the natural fracture system of the producing formation while providing additional safety measures. It also prevents the accidental or deliberate discharge or flaring of methane during drilling and production.

  • Patent number: 11028669
    Abstract: The tool assembly includes a main body and a bypass assembly. The main body has an off-set through bore and a cavity to fit the bypass assembly. The cavity includes a cavity surface, a first fluid bypass port, a second fluid bypass port, and a pressure inlet port. There is also a flow restrictor in fluid connection with the pressure inlet port. The bypass assembly includes a bypass housing, a pressure chamber, a piston with a first piston position and a second piston position, and a spring assembly. A pressure differential created by fluid flow through the pressure chamber and flow restrictor actuates the piston between the first piston position and the second piston position. The proportional flow through the tool assembly and through the bypass ports can now be controlled to perform the downhole work, including drilling and hole cleaning.

  • Patent number: 11002092
    Abstract: A device (10) for facilitating the transport of an apparatus A along an upward or downward directed conduit or bore hole including a drill string (12) is described. The device (10) has a body (13) having an upper body portion (20) and a lower body portion (22) which are coupled together and movable axially relative to each other. A fluid flow path (58) internal of the body (13) selectively enables fluid to flow through the body (13). A first valve system 60 located at a first end of the internal fluid flow path (58) is operable by a pressure differential between a region external of the body (13) and the internal fluid flow path (58). A second valve system (51) is located at second end of the internal fluid flow path. The second valve system (51) is operable by relative movement between the upper body portion (20) and lower body portion (22).

  • Patent number: 11002080
    Abstract: A cutter block includes a formation facing surface having a staged cutting profile and one or more stabilizer pads may be located between reaming portions. A shorter stabilizer pad or no stabilizer pad may be at the gauge of the cutter block. A spline on the cutter block and used by a downhole cutting apparatus to move the cutter block may intersect the formation facing surface. The spline may form an extension that increases a width of the formation facing surface. The extension may be located at a stabilizer pad to expand the stabilizer pad, such that the extension rotationally leads or trails cutting structure of the cutter block. When the cutter block is expanded, a stabilizer pad may be at a pilot diameter of a wellbore, while some cutting elements may be radially outside, and others radially within, the pilot diameter of the wellbore.

  • Patent number: 10961781
    Abstract: Anti-rotation pad assemblies are provided for restraining rotation of a non-rotating housing in geologic drilling system. The anti-rotation pad assemblies include extensible members, which extend from an internal cavity in the anti-rotation pad assemblies and are capable of engaging a wellbore wall. The extensible members may include rollers that are biased radially outwardly to engage the wellbore wall such that the anti-rotation pad assemblies may move axially within the wellbore while restraining the non-rotating housing in a particular rotational orientation. Flow ports are defined in the anti-rotation pad assemblies to encourage mud flow through the internal cavity, and thereby discourage the accumulation and solidification of drilling fluids around the extensible members. The extensible members thus remain free to move under the bias of a biasing mechanism within the internal cavity and can thus effectively maintain the rotational orientation of the non-rotating housing in the wellbore.
