Water shut-off

The best way to tackle unwanted water production is to shut it off downhole

Water shut-off

  • Applications
    Downhole water shut-off, setting straddle packers, shifting sliding sleeve doors, shifting flow control devices
On a global level, operators produce approximately three times as much water as they do hydrocarbons from their wells, i.e. for every 100 million barrels of oil equivalent (boe) per day in 2018, a further 300 million barrels of water was produced.

Unwanted water production

There is a cost associated with handling this much water. It either needs to be disposed of by re-injecting it into the reservoir or a separate disposal well.

Some water production is inevitable but the best way to tackle unwanted water production is to shut it off downhole.
