Real-time data provides answers
Saudi Aramco chose ACTive Isolation for an accurate and effective way to
isolate the zone, to reduce water cut, and to regain production.
ACTive Isolation also provided a rigless solution by deploying a
through-tubing inflatable packer on CT and a cement plug to isolate the
water-producing zone at the toe of the horizontal open hole.
The initial run confirmed well accessibility and downhole temperature
for accurate cement slurry design. On the second run, the through-tubing
inflatable packer was run to the depth of the oil/water interface. After the
depth was confirmed, a ball was dropped in the CT to set the packer. Real-time
downhole measurements ensured the packer was properly located and set. On the
third run, CT spotted cement on top of the inflatable packer.
Oil production revived
The kill fluids were displaced with nitrogen, which was confirmed at
surface by monitoring downhole pressure. This rigless solution reduced
completion time by half.
With the well back in production, water cut decreased by 50% and oil
production increased by 1,000 bbl/d.
