  • Directional drilling systems
    Patent number: 12078064
    Abstract: A directional drilling assembly includes a downhole piston and an uphole piston. A downhole piston diameter of the downhole piston is smaller than an uphole piston diameter of the uphole piston diameter. This may allow the downhole piston and/or the uphole piston to be located closer to the bit, thereby improving the maximum DLS of the system.
    Type: Grant
    Filed: April 6, 2020
    Date of Patent: September 3, 2024
    Assignee: Schlumberger Technology Corporation
