Abstract
A downhole vibration assembly includes a valve positioned above a rotor that is disposed at least partially within a stator. The rotor is operatively suspended within an inner bore of a housing and configured to rotate within the stator as a fluid flows through the vibration assembly. The valve includes a rotating valve segment and a stationary valve segment each including at least one fluid passage. The rotating valve segment rotates with a rotation of the rotor. In an open position, the fluid passages of the valve segments are aligned and a fluid flows through the valve. In a restricted position, the fluid passages of the valve segments are partially or completely unaligned, thereby temporarily restricting the fluid flow through the valve to create a pressure pulse. The unobstructed pressure pulse is transmitted through the drill string or coiled tubing above the valve.
