Abstract

A string of concentric casings (111) to (114) are located in the seabed (102). An abrasive cutting medium 103 is ejected at high pressure from a nozzle (101) at the end of a pipe (104) to cut through the casings (111) to (114) such that their upper parts, and any associated wellhead, can be removed. Air is delivered at high pressure into the inner casing (111) via pipe 122therebyto displace seawater (123) in the inner casing (111) so that, instead of trying to cut through seawater, the abrasive water jet (103) cuts in air, which is very much more efficient. In Figure (3), socks (161) are filled with a settable material and inserted intheir unset state into cement ports (151). When the material sets, it prevents the general escape of compressed air. Various other plugging devices are also disclosed.
