Located in the North Sea, one operator whilst carrying out a plug and abandonment operation on one of their wells, run 5 joints of 13 3/8” casing  inside the 30” (310ppf) conductor, with a casing cutter within the BHA for cutting the 30” conductor 

With a requirement to centralize the 13 3/8” whilst allowing the buttress casing to be rotated from surface at 60 RPM for 30 – 40 minutes to make the cut - Ray Oil Tool were called upon to provide a solution.

As shown in the images, we manufactured the 13 3/8” x 26.5” O.D x 12” solid aluminium straight blade centralisers in two halves, making them easier to handle manually. This would allow the centralisers to be installed at the wellsite. Both halves are fitted over the pipe and fastened together by 4 heavy duty stainless steel nuts/bolts and held in place with 13 3/8” stainless steel stop collars.

By gaining the advantage of allowing the pipe to be rotated from surface, cost savings are made within the BHA design. In addition the centralizers can be in most cases reused many times over again.

At Ray Oil Tool we have the capability to manufacture any custom size required, with quick turn around lead times.
