How it works
The treatment reduces water mobility in the water-bearing zone without sealing the producing interval.
Cross-section of a cased well. Oil-bearing rock is perforated above a water-bearing zone. The treatment sits in the water-bearing zone, closing the water path while the oil path into the well stays open.
The problem
Produced water raises lifting and handling cost, loads surface facilities, and shortens the economic life of a well. It arrives through the wellbore, as flow behind pipe or a tubing and casing leak, or through the reservoir, as a high-permeability streak, fingering, coning, or a natural fracture.
The treatment
An inorganic treatment pumped into the producing interval, where it mineralises in place to form low-solubility precipitates that occupy the interconnected pore space carrying water. Injected at a viscosity close to water, it forms no gel in the tubing and can be removed by acid injection.
What it gives you
Lower water cut
Cut the volume of water lifted, separated, and disposed of per barrel of oil.
Reversible
The treatment can be removed by acid injection if it affects the producing zone.
No gel in the tubing
Pumps at water-like viscosity, so there is no gelation risk on the way down and no breaker needed on the way out.
Nothing to retrieve
The treatment is a fluid that reacts and stays. There is no hardware downhole to mill out.
