They obviously thought about the sidetrack option “The current method of recovery, although slow, is considered substantially cheaper than the alternative of drilling around the lost pipe and the casing hanger, and re-drilling the well section between 9,150’ and 15,397’.” The recovery option GDN chose most likely based on the lost pipe; would they (consultants/drilling contractor) know with confidence regarding onsite drilling contractors electronic/technical information of what the situation is most likey going to be below this area of recovery operation, in a well such as this one or any other well with this type of problem or do they find out after recovery?
