Patent number: 11814908Abstract: A formation tester tool assembly includes a seal member mounted on rigid stabilizer that contacts a borehole wall separately from the seal member, so that seal exposure to a stabilization load that presses the tool against the borehole wall is limited or reduced by contact engagement of the stabilizer with the borehole wall. The stabilizer is provided by a hydraulically actuated probe piston reciprocally movable relative to a tool body on which it is mounted. The seal member is in some embodiments movable relative to the probe piston, for example being configured for hydraulic actuation to sealingly engage the borehole wall while the tool body is stabilized by action of the probe piston.Type: GrantFiled: May 23, 2022Date of Patent: November 14, 2023Assignee: Halliburton Energy Services, Inc.Inventors: Ping Sui, Nanjun Liu, Varun Gupta, Charles Kuo

Patent number: 9988849Abstract: Wellbore tools may use carbon nanoforests to reduce the access of abrasive particles to compressible sealing elements of joints of the wellbore tool. In some instances, a wellbore tool may include a joint comprising two elements having opposing mating surfaces that define a gap; a compressible sealing element arranged between the opposing mating surfaces and configured to seal a portion of the gap, thereby defining a sealed segment and an unsealed segment of the gap; and at least one carbon nanoforest disposed within at least a portion of the unsealed segment and coupled to at least one of the opposing mating surfaces.Type: GrantFiled: July 18, 2013Date of Patent: June 5, 2018Assignee: Halliburton Energy Services, Inc.Inventors: Ping Sui, David Duckworth, Gary Weaver
