Patent number: 11975389Abstract: Methods of manufacturing monolithic components with complex design features and functionally graded properties in any spatial direction may include forming of outer shell with an additive manufacturing process, loading the shell with bulk material and exposing the loaded shell to a hot isostatic pressing (HIP) process. The combination of the additive manufacturing process and the HIP process forms a diffusion bond between the outer shell and the bulk material resulting in a monolithic component with functionally graded properties. The outer shell may include an exterior surface and an inner passage formed with relatively hard surfaces to accommodate fluids in a wellbore.Type: GrantFiled: November 14, 2019Date of Patent: May 7, 2024Assignee: Halliburton Energy Services, Inc.Inventors: Krutibas Panda, Larry Chambers, Neelesh Deolalikar

Patent number: 11891863Abstract: Hardfacing is used to protect wear surfaces of drill bits and other downhole tools. A hardfacing member can be formed by heating a metal matrix material, e.g., via a laser process, injecting a plurality of particles into the heated metal matrix material, disposing the mixture on at least a portion of a substrate thereby forming a hardfacing member having a particle-embedded metal matrix material, and attaching the hardfacing member to a main body.Type: GrantFiled: August 29, 2018Date of Patent: February 6, 2024Assignee: Halliburton Energy Services, Inc.Inventors: Krutibas Panda, Brian Lee Doud

Patent number: 11828114Abstract: Systems and methods for cold-spraying coatings on rotors in motor assemblies for improving reliability of motor assembly use downhole in wellbores is provided. For example, a motor assembly can include a stator positioned downhole in a wellbore and rotor coupled to the wellbore. The rotor can include a base material and a first coating deposited onto the base material via cold spraying for reducing damage to the rotor. The first coating may include sprayed particles that have a melting point temperature that is higher than a temperature of a gas used in the cold spraying. In some examples, the rotor may include a second coating deposited onto the first coating via cold spraying, high velocity oxygen fuel coating, or high velocity air fuel. The first coating may have a first hardness that is less than a second hardness of the second coating.Type: GrantFiled: December 28, 2021Date of Patent: November 28, 2023Assignee: Halliburton Energy Services, Inc.Inventors: Krutibas Panda, Philip Park Hung Leung

Processing route to design and manufacture highly configurable non-magnetic down-hole sensor collars
Patent number: 11654506Abstract: Drill collars may be constructed using solid-state welding processes. Solid-state welding produces robust drill collars with high fatigue lifespans and permits individual segments of the drill collar to be optimized based on their intended use. A drill collar may be formed of a first segment with a different material, density, modulus of elasticity and/or geometry than an adjacent second segment fused thereto. If a segment of a drill collar is damaged in use, the damaged segment may be removed and replaced, possibly without de-rating the drill collar. Methods of forming the solid-state welds may include friction welding adjacent segments to one another such that features in each segment are circumferentially aligned when the weld is formed. Supplemental energy sources may provide additional heat at the welded surfaces to ensure the segments are effectively fused.Type: GrantFiled: October 22, 2021Date of Patent: May 23, 2023Assignee: Halliburton Energy Services, Inc.Inventors: Krutibas Panda, Michael Dewayne Finke, Brian David Breaux, Gregory D.

Manufacturing a rotary valve can include combining diamond particles in a press with silicon and applying temperature and pressure to produce a piece of ScD. Interposing a compound between the piece and a structure and brazing them by heating the compound between 700-1200 degrees Celsius. Forming ports and flow paths in the piece by machining the piece with an Electrical Discharge Machining (EDM) tool.Type: GrantFiled: July 17, 2017Date of Patent: April 28, 2020Assignee: Halliburton Energy Services, Inc.Inventors: Krutibas Panda, Neelesh Deolalikar, Larry Chambers

Publication number: 20190249494Abstract: A rotary valve can include a housing, a manifold with multiple flow paths can be fixedly mounted to the housing. A rotary actuator with a first surface can be rotatably mounted within the housing, and a valve seat with a second surface can be fixedly attached to the manifold, where the second surface can sealingly engage the first surface. The rotary actuator can include a gap that selectively aligns with respective ones of valve seat ports as the rotary actuator rotates relative to the valve seat, thereby selectively pressurizing one or more actuators. A system and method can include a rotary valve that selectively causes pads to extend at a predetermined orientation in the wellbore to steer a drill bit. The azimuthal orientation of a rotary actuator of the valve can determine which pads are extended and which are retracted as the drill bit rotates.Type: ApplicationFiled: July 17, 2017Publication date: August 15, 2019Inventors: Daniel Winslow, Larry Chambers, Neelesh Deolalikar, Krutibas PANDA
