Abstract:
A resonant extractor system configured to use rotational energy provided by a top drive system to apply vertical oscillating motion to attached tubular or drilling equipment. The extractor includes a rotational component, an oscillation component, and an assembly of engagement features. The top drive system may rotate the rotational component about a vertical axis. In certain embodiments, the rotational component is a housing, the oscillation component is a quill, and the engagement features include a cam disposed on a shaft. The shaft is coupled to and extends radially into the housing, and the cam disposed on the shaft, which features an eccentric geometry relative the shaft, maintains contact with a lip extending from the quill in the housing. As the housing rotates, the eccentric cam rotates, raising and lowering the quill, which is configured to couple with tubular or drilling equipment.
