Patent number: 11448605Abstract: An apparatus comprises a base plate, a first fixed post, a second fixed post, a first actuator, a second actuator, a third actuator, a first test sample grip, and a second test sample grip. The first fixed post and the second fixed post are coupled to the base plate at one side thereof. The first actuator, coupled to the first fixed post and the second fixed post, rotates a test sample along an axis that runs parallel to and halfway between the first fixed post and the second fixed post. The second actuator, coupled to the first fixed post and the second fixed post, displaces the test sample along the axis that runs parallel to and halfway between the first fixed post and the second fixed post. The third actuator, coupled to the first fixed post and the second fixed post, rotates the test sample along the axis that runs parallel to and halfway between the first fixed post and the second fixed post.Type: GrantFiled: February 14, 2020Date of Patent: September 20, 2022Assignee: PSYLOTECH, INC.Inventors: G.

Publication number: 20210374311Abstract: A method, stored on a non-transitory medium and executed by a processor, for simulating strain induced orthotropy for a material, comprises calculating three (3) principal strain directions of the simulated material, calculating three (3) distortional strains for the simulated material, and calculating three (3) dilatational strains for the simulated material. The method further comprises calculating free energy for the simulated material, the calculated free energy being calculated from the calculated three principal directions of the simulated material, the three distortional strains and the three dilatational strains. The method yet further comprises calculating, via the calculated free energy, a stress for the simulated material based on the calculated free energy for the simulated material.Type: ApplicationFiled: June 8, 2021Publication date: December 2, 2021Inventor: G.

Patent number: 8695717Abstract: Conventional formation evaluation with dual inflatable packers includes the steps of pressurizing the packers so as to isolate an annular portion of the borehole wall, collecting one or more samples of formation fluid via the isolated portion of the borehole wall, and depressurizing the packers so as to permit movement of the mandrel within the borehole. A sampling method and apparatus that utilize one or more of the following to advantage is provided: restricting deformation of the packers during inflation using an annular bracing assembly; actively retracting the packers using ambient borehole pressure; and substantially centralizing the mandrel intermediate the packers so as to resist buckling of the mandrel.Type: GrantFiled: August 22, 2012Date of Patent: April 15, 2014Assignee: Schlumberger Technology CorporationInventors: William E. Brennan, III, Colin Longfield, Alexis Arzoumanidis, Allessandro Caccialupi

Publication number: 20040157066Abstract: A protective hardcoating system is provided for a metallic substrate of a downhole tool. The metallic substrate is generally characterized by a thermal coefficient. The hardcoating system includes a hardface coating that is applied onto the substrate to protect it against wear. The hardface coating includes an interface section positioned adjacent to the substrate and defining an interface therewith, and a hard surface section positioned externally of the interface section. Further, the hard surface section includes an exposed surface. In this hardcoating system, the interface section and the surface section have a composition including a predetermined hardness component constituency and a thermal coefficient at least partially attributable to the hardness component constituency.Type: ApplicationFiled: February 7, 2003Publication date: August 12, 2004Inventor: G.
