Core flood tests are effectively utilised for management of field specific scaling issues when they are included as part of a series of tests to select ‘Best in Class’ scale inhibitors, for either production or produced / sea water injection wells. The primary aim of core testing is to evaluate (1) formation damage potential, and (2) the chemical efficiency, e.g. the potential return lifetime.
Scale inhibitor retention and release core floods can be performed either in isolation or in combination with formation damage / injectivity assessment. Scaled Solutions has extensive knowledge and experience of current inhibitor chemistries and have been integral in the development of appropriate analytical techniques to determine inhibitor concentration.
Inhibitor return data from core flood experiments is used to derive a dynamic retention/release isotherm specific to the chemical and reservoir rock under the test conditions.
Our in-house Place iT™ software is utilised for field treatment modelling using the return isotherm to relate the core test results to the field scale.
Scaled Solutions have been instrumental in developing advanced protocols for scale inhibitor core flood testing through the SWELL Joint Industrial Project. To learn more, visit the SWELL JIP page.
