Abstract: According to one aspect, there is provided a drilling motor assembly having a power section configured to generate torque, a transmission section coupled to the power section, and a bearing section coupled to the transmission section, the bearing section configured to couple to a drill bit. The transmission section includes a housing assembly having a bore formed therethrough, the housing assembly having a central axis defined therethrough and the bore having a central axis defined therethrough, in which the central axis of the bore is radially offset from the central axis of the housing assembly.

Abstract: A rotating object balancer may include an insert configured for securing to an object and having a chamber for placement of balancing elements and a curable solution, a rotational system configured to rotate the object at high-speed, a monitoring system for monitoring vibrations of the object rotating at high-speed, and a curing tool configured for curing the curable solution when the object has reached a balanced state. A method of balancing may be performed by the balancer and a balanced object may be created by the balancer.
