A downhole oscillation tool includes a Moineau-type positive displacement pulse motor and a valve assembly for use in a drill string. The pulse motor includes a rotor configured to nutate within the bore of a stator. The rotor has at least two helical lobes that extend the length of the rotor, and the stator bore defines at least three helical lobes that extend the length of the stator. The valve assembly includes a first valve plate connected to the bottom end of the rotor and abuts the second valve plate to form a sliding seal. The second valve plate is fixedly coupled to the stator and remains stationary. First valve ports extend axially through the first valve plate, and second valve ports extend axially through the second valve plate. The first valve ports and second valve ports intermittently overlap as the first valve plate slides across the second valve plate to create pulses in the drilling fluid which is pumped through the tool to power the motor and valve assembly. The tool can generate pulses of different amplitudes and different wavelengths in each rotational cycle. The tool further includes a drop ball assembly configured to activate and deactivate the tool.

Downhole oscillation apparatus

A progressive cavity positive displacement motor having a solid metal stator and a rotor having an elastomeric seal layer on its outer surface, as well as a method of manufacturing the motor. The elastomeric seal layer on the rotor can be formed by extruding the uncured elastomer, applying the extrusion to the metal rotor core and machining the cured elastomer to produce a uniform thickness seal layer. The elastomer can be made from a high molecular weight elastomer compound. Graphene additives can further enhance the performance characteristics of the elastomer.

Mud motor inverse power section

A modified filter screen for use in a downhole drilling operation is disclosed. The filter screen is able to be installed at the surface of a well, and is pin-loaded for easy access and maintenance. The modified filter screen may be retained within a section of pipe below the top drive above the rig floor by allowing dowel pins on the section of pipe to engage with latch slots on the filter screen. The modified filter screen may also be retained by engaging a threaded connector on the filter screen with a threaded connector on the interior of the section of pipe or by utilizing pins and/or retaining rings.
