OS ACETIC ACID - Acetic Acid

 

 

Well Completion & Formation Damage Treatment

Wellbore fluids used during drilling and completion can contain many polymers, clays and other plugging polymers that can damage the formation and impair the reservoir resulting in reduced production. In order to clean the reservoir and remove the plugging agents that are impairing the formation various acids including acetic acid and other solvents are used. 

 

Product Information 

OS ACETIC ACID is an organic acid used in well stimulation, workovers and completions. OS ACETIC ACID is less corrosive than the traditionally used hydrochloric acid (HCL). OS ACETIC ACID treatments are more easily inhibited or retarded for treatments of a long period. Less corrosive than the commonly Using OS ACETIC ACID is essential in applications when treating high temperature wells.  OS ACETIC ACID can be used with HCL and other acids.

 

Typical Physical Properties 

Appearance   -   Clear liquid                         

Assay, CH3COOH   -   79.0 – 81.0 % m/m

Advantages  

OS ACETIC ACID is a weakly ionised, slow reacting organic acid and is easier to inhibit against corrosion than HCL. It is useful in stimulating wells with alloy tubular. It naturally sequesters Iron thus reducing Iron precipitation.

 

Application   

OS ACETIC ACID is used in oil and gas well treatments to clean the wellbore. It is normally blended with other acids such as hydrochloric acid in order to enhance performance.

 

Packaging

OS ACETIC ACID is packaged in 215 kg drums.
