Abstract
The present invention addresses to a method for quantifying the loss of injectivity associated with corrosion products, comprising a methodology to estimate the suspended solids generated from the corrosion process of injection strings, aiming at allowing the identification of wells with problems, definition of strategies and damage removal, as well as acting preventively and avoiding severe losses of injectivity and string degradation, consequently avoiding production losses. The developed method can be applied to any well with available injectivity history, where tests are required on representative rock samples and under controlled conditions (known water quality) for reference and application of the experimental correlation.
