Challenge: Shut off water from lower horizontal
openhole section in a producing well in a naturally fractured depleted
carbonate reservoir.
Solution: Deploy ACTive Isolation live CT zonal
isolation service and CoilFLATE coiled tubing through-tubing inflatable packer
to shut off water in an openhole horizontal well using a combination of
mechanical and chemical isolation techniques.
Results: Eliminated water production by 4,000 bbl/d
and increased oil production by 30% without any subsequent acidizing.
