Abstract
A lifting apparatus for supporting tubular goods that can be used to perform down-hole operations in oil and gas wells. The lifting apparatus has push and pull capability, a minimal footprint, and requires minimal surface area to operate. The support apparatus can be used to jack and remove casing and other pipe, such as during plugging and abandonment operations, and to perform other rig-less downhole well operations.
Claims
exact text as granted — not AI-modifiedWhat is claimed:
1 . An apparatus for conducting operations in a well comprising:
