Zonal Isolation in a U-shaped Well using Coiled Tubing and Well Tractor?

摘要

An 80m long retrievable “one-run” straddle assembly was successfully installed in order to shut off a gas breakthrough in the 130 degrees deviated reservoir section of a “U shape/Fish hook” sub sea oil producer in the Njord field. Coiled tubing with an internal electric line in combination with a tandem fluid driven tractor was used to convey the straddle assembly.
