scale inhibition in oil fields

[Tarik]

we are used to squeeze scale inhibitors from time to time to help prevent scale deposion due to incompatibility of injection water and formation water.

We are looking into the feasibility of injecting scale continously in the injector wells. Does any one know if this is an industry standard? any comments

Hey,

We also use scale inhibitors in our our oil field.Infact we use chemical in a form of cocktail( Corrosion inhibiotr + scale inhibitor).But normal chemical injcetion is downstream of choke and upto the pieline end..
But what about well tubing and especialy the producing zone area. What is the possibility that scaling can occur in well tubing and pay zone.
Pls help me if anybody has knowledge on this.
thanx
