A customer in the Gulf of Mexico identified a restriction in the wellbore while completing a deepwater well. The intended completion equipment required a 9.000-in. minimum inside diameter (ID) through the wellhead, but a 33-in. section of the dummy hanger retrieval sub had a smaller 8.569-in. ID. Leaving as is would require changes to the desired completion design while also complicating future operations. To avoid such measures, the operator reached out to Baker Hughes, a GE company (BHGE), for a solution to remove the restriction without damaging the casing.
