The present invention provides a device for removing well casing from plugged and abandoned oil wells. The invention includes a unitary platform structure sufficiently small that the structure may be transported by boat to offshore well platforms and be lifted onto the well platform as a single unit. The platform also has a center station with an opening allowing the casing to pass therethrough. The device further includes at least one lifting means, which lifts the well casing through the center station. The present invention will serve many of the purposes of much larger drilling rigs or work over rigs typically employed on oil and gas well platforms. The present invention will be much quicker to transport and requires considerably less set-up time than dig rigs or work over rigs.
A self-contained well service rig comprising:
A process for extracting well casing with a movable platform having a first and second lifting device contained thereon and said second lifting device having a rotary means attached thereto, said process comprising the steps of:
