For decommissioning platform wells Mirage designed a system for drilling and pinning the multiple casing strings. This has now been used extensively around the world.
North Sea – UK & Norway, Gulf of Mexico - surface and sub sea
For surface cuts the drill unit has a split joint that is clamped onto the casing and then an auto feed system to feed the cutter through, while the band saw has a mechanical vice jaw that clamps around the casing and then an auto feed system to feed the blade through. A 48” multiple casing is drilled in approx 15 minutes and cut in approx 40 minutes, giving a fast, efficient, cost effective cold cutting method for inserting lifting pins into multiple casing strings and cutting multiple casing strings with or without grouted annuli.Contact us for more information
