Patent number: 10724299Abstract: Reinforced directional drilling assemblies and methods of forming reinforced directional drilling assemblies are provided. Strengthening materials may be incorporated into a resilient layer and/or a polymer-based composite material within a directional drilling assembly to improve the durability and performance of a power section within the directional drilling assembly. Inclusion of strengthening materials within a directional drilling assembly may provide a method to detect the status of a power section and send a signal from downhole upon detecting status of the power section. Inclusion of strengthening materials also may provide a method to collect data about operating conditions, including pressure, temperature, torque, RPM, stress level, shock, vibration, downhole weight on bit, and/or equivalent circulating density to send to the surface or to MWD/LWD systems. The strengthening materials may collect data by themselves or in conjunction with a sensor.Type: GrantFiled: July 16, 2018Date of Patent: July 28, 2020Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Hossein Akbari, Geraint Jones

Patent number: 10233926Abstract: The present invention recites a method of fabricating a stator for a downhole motor, the method comprising the steps of providing a stator tube having an interior surface and applying a bonding agent to the interior surface of the stator tube. Additionally, a mandrel is positioned within the stator tube, the mandrel having an outer geometry that is complimentary to a desired inner geometry for the stator. Furthermore, a reinforcing material is introduced into the stator tube to fill space between the mandrel and the interior surface of the stator tube and subsequently solidified to bond the reinforcing material to the interior surface of the stator tube. The mandrel is then removed from the bonded stator tube and reinforcing material such that a stator is fabricated.Type: GrantFiled: July 14, 2014Date of Patent: March 19, 2019Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Hossein Akbari, Julien Ramier, Olivier Sindt

Patent number: 8444901Abstract: The present application discloses a progressive cavity motor or pump component, either stator or rotor, which provides a high glass transition temperature polymeric surface on the component which becomes resilient at or below the expected operating temperature of the motor or pump, but which remains solid at ambient temperatures, along with a method of fabricating either a stator or a rotor with such surface characteristics. Since the surface becomes resilient, the progressive cavity pump operates efficiently at temperatures above the glass transition temperature of the selected polymeric surface.Type: GrantFiled: December 31, 2007Date of Patent: May 21, 2013Assignee: Schlumberger Technology CorporationInventors: Olivier Sindt, Hossein Akbari, Julien Ramier
