Abstract:
A downhole assembly and method are provided for selective activation of a motor in a drilling string. The downhole assembly includes a stator and a rotor assembly. The rotor assembly comprises a rotor body having a fluid passage extending between an inlet and an outlet, the fluid passage extending through at least part of the length of the rotor; and a ball catch component comprising a receiving end and an interior seat for receiving and retaining a blocking implement, and a fluid passage. When no blocking implement is retained in the rotor assembly, the fluid passage permits flow of drilling fluid entering the receiving end to the fluid passage of the rotor body. The fluid thereby bypasses the motor, which is not activated. When a blocking implement is in place, drilling fluid flows around the ball catch component and into the motor to thereby activate the motor.

Claim (Index 15):
A method of activating a motor assembly in a drilling string, the method comprising:\n providing in the drilling string a motor, the motor comprising a stator and a rotor assembly, the rotor assembly comprising:\n a rotor body having a fluid passage extending between an inlet and an outlet, the fluid passage extending through at least part of the length of the rotor; and \n a catch component provided on the rotor body, the catch component comprising a receiving end and an interior seat for receiving and retaining a blocking implement, and a fluid passage permitting flow of drilling fluid entering the receiving end to the fluid passage of the rotor body when no blocking implement is retained in the rotor assembly, the receiving end permitting flow around the catch component when a blocking implement is retained in the rotor assembly, \n while no blocking implement is retained in the rotor assembly, introducing drilling fluid into the drilling string such that a substantial part of the drilling fluid enters the receiving end of the catch component and passes through the fluid passage of the rotor body and exits through the outlet, the substantial part of the drilling fluid thereby bypassing the motor; positioning a blocking implement in the rotor assembly such that the blocking implement is retained on the interior seat of the catch component so as to substantially block drilling fluid flow through the fluid passage of the rotor body, the blocked drilling fluid being thereby redirected around the catch component and into the motor to thereby activate the motor.
