Challenge: Customize a FORTRESS premium
isolation valve to ensure compatibility with the ExxonMobil proprietary
openhole isolation packer to be installed with UltiPac Alternate Path
extended-reach gravel-pack screens offshore Sakhalin Island
Solution: Modify the shifting profile of the
isolation valve to differentiate it from that of the packer, thereby preventing
accidental actuation of both
Results: Isolated the production zone from
upper completion activities after a 100%-complete openhole gravel pack and
subsequently opened the FORTRESS valve for production, with zero NPT,
successfully implementing ENLs completion design
