  • Method of lining an inner surface of a tubular and system for doing same
    Patent number: 11198152
    Abstract: A method of lining an inner surface of a tubular with a polymer, includes positioning a polymer injecting head within the tubular, forming an annular space between the injecting head and an inner surface of the tubular, injecting polymer through the injecting head into the annular space, and moving the polymer injecting head longitudinally relative to the tubular while injecting polymer.
    Type: Grant
    Filed: August 5, 2019
    Date of Patent: December 14, 2021

  • Method for forming a mud motor stator
    Patent number: 11148327
    Abstract: A method of forming a mud motor stator having a passage including a first end defining a first opening, a second end defining a second opening and an intermediate portion extending therebetween includes introducing a liner material into the passage at one of the first end and the second end of the stator, inserting a mandrel having a contoured surface into the passage through one of the first end and the second end of the stator, shifting one of the mandrel and the stator relative to the other of the mandrel and the stator, and flowing the liner material over the contoured surface of the mandrel from the one of the first and second ends toward the other of the first and second ends to form a liner on the inner surface of the passage.
