  • Patent number: 10656301
    Abstract: An example downhole tool for determining ranging parameters involves placing a guard electrode between a survey electrode and a return electrode where the survey electrode and the return electrode are separated by a gap subs. A fixed, predictable, and stable path for the survey current is formed that is independent of the conductivity of the mud or conductive targets resulting in a formation current that may be used to estimate the direction, orientation or distance of a conductive target. The formation current is then a stable current that excites a conductive target in the same way regardless of the conductivity of the mud so as to obtain a mud-independent reference signal in single-well ranging.

  • Patent number: 10619437
    Abstract: A downhole assembly and method are provided for selective activation of a motor in a drilling string. A rotor in a Moineau-principle motor is provided with a fluid passage therethrough and a catch that can receive and retain a blocking implement. A driveshaft is operably connected, for example using universal joints, to the rotor and a first valve component. The driveshaft is effectively supported by a thrust transmission assembly comprising a thrust unit and hanger resting on a spring so that the first valve component is not in contact with a second valve component. When a blocking implement is in place, drilling fluid activates the motor and also increases pressure on the rotor, causing the thrust transmission assembly to move the first valve component down into contact with the second valve component.
