Patent number: 10408053Abstract: Systems, devices, and methods for estimating a value of a parameter of interest of an earth formation intersected by a borehole. Methods include conveying a carrier in the borehole having disposed thereon an acoustic imaging tool including at least one convex linear phased array module, each of the at least one module comprising a rigid shell forming a compartment containing a piezoelectric component array; using the acoustic imaging tool to take acoustic measurements of the borehole; and using the acoustic measurements to estimate at least one parameter of interest. Each module may be self-contained. The tool may include a plurality of modules circumferentially arrayed about a portion of the acoustic tool. Methods include individually removing one selected module from the acoustic tool. Methods may include selecting an outer tool diameter the same as an inner borehole diameter borehole and selecting a maximum number of modules fitting the outer tool diameter.Type: GrantFiled: May 19, 2016Date of Patent: September 10, 2019Assignee: Baker Hughes, a GE company, LLCInventors: Brian Breaux, James V. Leggett, III, Steffen Toscher, Roger Steinsiek

Patent number: 10056815Abstract: An apparatus for use in a borehole may include a rotor having at least one set of magnetic elements and a cylindrical stator having a winding flowing current in a direction transverse to a long axis of the stator. The polarity of each magnetic element of the rotor may be arranged to alternate along a long axis of the rotor. The stator may be in sliding engagement with the rotor and have a core formed at least partially of laminations aligned along a plane co-planar with the long axis of the stator. Energizing the winding principally causes relative sliding between the rotor and the stator. A method for performing an operation in a borehole includes forming a well tool having at least one linear motor as described above, conveying the linear motor into the borehole, and operating a well tool by activating the linear motor.Type: GrantFiled: September 30, 2014Date of Patent: August 21, 2018Assignee: BAKER HUGHES, A GE COMPANY, LLCInventors: Sebastian Tegeler, Steffen Toscher, Otto N.
