Abstract: A snubber device for reducing shocks and vibrations in a downhole tool. The snubber includes a main body extending between upper and lower connector ends. The main body is defined by one or more cut-out portions. One or more elastomeric elements are held within the one or more cut-out portions. The cut-out portions provide flexibility to the main body. The elastomeric elements absorb shocks and vibrations and are conveniently replaceable when excessive wear reduces their shock and vibration absorbing capacity.

Abstract: A dampener device configured for incorporation into a downhole tool in a drilling system for absorbing axial, lateral and torsional shocks and vibrations to protect instrumentation during a drilling process includes a main sleeve having a main cavity containing a main spring and a first elastomeric ribbon interleaved between coils of the main spring. An adapter is connected to or formed monolithically relative to the main sleeve. The adapter is configured for connection to a first tool component. A plunger is configured to compress the main spring and a connector is configured for connection to a second tool component. The connector is attached to or formed monolithically relative to the plunger. A shaft extends between the adapter and the connector. The shaft is provided with an anti-rotation structure.

Abstract: A dampener device is configured for incorporation into a downhole measurement tool in a drilling system, for absorbing axial, lateral and torsional shocks and vibrations to protect measurement instrumentation located above the device during drilling. The device includes: a main sleeve having a main cavity containing a main spring; an adapter connected to or formed monolithically relative to the main sleeve, the adapter configured for connection to a first tool component; a plunger configured to compress the main spring; a connector configured for connection to a second tool component, the connector attached to or formed monolithically relative to the plunger; a shaft extending between the adapter and the connector, the shaft provided with an anti-rotation structure; and one or more passages leading from the outside of the device into the main cavity. The passages are provided to allow drilling fluid to enter the main cavity to act as vibration dampening fluid.
