Bespoke hydraulic work platform - land well
During a workover a land-well client encountered cement higher than expected in the casing strings. The only solution would be to drill out the cement and re-run the 10.3/4” and 7” casing.
Budget constraints meant a rig would be out of the question for the job – so Claxton had to designed a system to pull and run the casing riglessly.
Claxton designed and manufactured a fully hydraulic work platform, the photos show the work platform being installed to the land storage cavern well with the annular B.O.P. in place.
The platform enabled the client to drill and clean out cement plugs using a downhole motor with the hydraulics of the Claxton-designed platform acting as a draw-works (in place of a rig). During the workscope, 10.3/4” and 7” Casings were pulled, re-run and landed into the surface wellhead using a combination of the work deck and 100 tonne telescopic crane.
The client was able to re run the casing and return the well to good order – at a fraction of the cost of employing a land drilling rig for the job.
Claxton’s experience in the design of bespoke interfaces also extends to tubing recovery interfaces, spreader beams, false rotary tables and complete casing recovery and abandonment packages to interface with existing infrastructure.
We completed the first-ever rigless abandonment in the North Sea using a completely-bespoke system designed and built in-house—saving the client hundreds of thousands of pounds when compared to completing the same task via a drilling rig.
