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.
