A review of factors that impact scale inhibitor mechanisms

Research output: Contribution to conferencePaper


This paper aims to further the knowledge available to front end engineering design (FEED) multidisciplinary teams, allowing many potential problems relating to production chemistry challenges to be addressed. This paper reviews the fundamental understanding of how various factors, conditions or environment impact scale inhibitor mechanisms, so that the results can be incorporated into
the FEED process. This paper highlights important findings which when pieced together give a beneficial overview of how various factors can significantly affect scale inhibitor performance. The following key areas are covered. (1) The influence of divalents on a scale inhibitor’s (SI) inhibition efficiency (IE) performance. (2) How IE performance relates to SI concentration/inhibition mechanism. (3) Nucleation types and inhibitor concentration required to prevent scaling. (4) The effect of flow regimes and temperature on the barium sulphate scaling process. (5) The sulphate level required to reduce or avoid squeeze treatments. (6) Scaling reactions catalyzed by foreign particles such as barite or sand. (7) The identification of inhibitor retention mode during squeeze treatment.
(8) Better-developed analysis techniques for less laborious pretreatment stages and new environmentally friendly products.
