Patent number: 11969797Abstract: A syntactic metal foam composite that is substantially fully dense except for syntactic porosity is formed from a mixture of ceramic microballoons and matrix forming metal. The ceramic microballoons have a uniaxial crush strength and a much higher omniaxial crush strength. The mixture is continuously constrained while it is consolidated. The constraining force is less than the omniaxial crush strength. The substantially fully dense syntactic metal foam composite is then constrained and deformation worked at a substantially constant volume. The deformation working is typically performed at a yield strength that is adjusted by way of selecting a working temperature at which the yield strength is approximately less than the omniaxial crush strength of the included ceramic microballoons. This deformation causes at least work hardening and grain refinement in the matrix metal.Type: GrantFiled: October 28, 2021Date of Patent: April 30, 2024Assignee: Powdermet, Inc.Inventors: Andrew Sherman, Brian Doud

Patent number: 11859489Abstract: An imaging agent, a method of production of the imaging agent, and the use of the imaging agent for microseismic monitoring of subterranean formations such as those generated during hydraulic fracturing. The acoustic emitting agent is tailorable for emission delay to ensure placement and frequency emission profiles for well region differentiation. This monitoring tool is highly useful in gas, oil, and geothermal well defining and stimulation monitoring.Type: GrantFiled: January 6, 2022Date of Patent: January 2, 2024Assignee: Powdermet, Inc.Inventors: Brian S. Werry, Brian Doud, Andrew Sherman

Patent number: 11739606Abstract: A temporary well isolation device which has an axial passage that comprises a temporary housing having an internal cavity containing a chemical material and a temporary barrier or plug member that can be actuated by an external mechanism to allow fluid to flow into the internal chamber and contact the chemical material in the internal chamber. When the chemical material is exposed to fluid, the chemical material causes the temporary housing to corrode, dissolve, and/or degrade.Type: GrantFiled: August 3, 2022Date of Patent: August 29, 2023Assignee: Terves, LLCInventors: Andrew Sherman, Brian Doud, Nicholas Farkas, Kurt Gilbert

Publication number: 20230226605Abstract: A heterogeneous composite consisting of near-nano ceramic clusters dispersed within a ductile matrix. The composite is formed through the high temperature compaction of a starting powder consisting of a core of ceramic nanoparticles held together with metallic binder. This core is clad with a ductile metal such that when the final powder is consolidated, the ductile metal forms a tough, near-zero contiguity matrix. The material is consolidated using any means that will maintain its heterogeneous structure.Type: ApplicationFiled: November 22, 2022Publication date: July 20, 2023Inventors: Mark Grogan, Brian Doud, Andrew Sherman

Publication number: 20230193713Abstract: An engineered composite system designed to be passive or inert under one set of conditions, but becomes active when exposed to a second set of conditions. This system can include a dissolving or disintegrating core, and a surface coating that has higher strength or which only dissolves under certain temperature and pH conditions, or in selected fluids. These reactive materials are useful for oil and gas completions and well stimulation processes, enhanced oil and gas recovery operations, as well as in defensive and mining applications requiring high energy density and good mechanical properties, but which can be stored and used for long periods of time without degradation.Type: ApplicationFiled: February 15, 2023Publication date: June 22, 2023Inventors: Brian Doud, Andrew Sherman, Nicholas Farkas, Brian Werry

Publication number: 20220372286Abstract: A degradable elastomeric material that is formed from a composite blend of elastomeric particles in a continuous degradable binder. The degradable binder is generally a water-soluble binder which has a temperature dependent solubility in water and brine systems. Such degradable elastomers are particularly useful in the fabrication of degradable oil tools, among other applications.Type: ApplicationFiled: August 4, 2022Publication date: November 24, 2022Inventors: Andrew J.

Publication number: 20220298916Abstract: The use of degradable components has become a more common practice in subterranean operations for such applications as temporarily isolating zones or diverting flow. A major concern of operators in using degradable tools is the ability to ensure that the tool has completely degraded and is no longer blocking or obstructing flow. This issue can be resolved through the use of degradable components that include one or more chemical additives that are released upon the partial or full dissolution of the degradable component, and which can be used to facilitate in the dissolution of the degradable component. The degradable component can optionally include tracer elements that are released upon the partial or full dissolution of the degradable component, and which can be detected at the surface to ensure the desired degradation or removal of the degradable component as well as hydraulic access to that stage.Type: ApplicationFiled: March 30, 2022Publication date: September 22, 2022Inventors: Andrew Sherman, Brian Doud
