Conceptual physicochemical models for scale inhibitor-formation rock interaction.

Oluyemi, G.F.

Abstract

The current oil industry approach to geomechanical evaluation of reservoir formations invaded by chemical inhibitors does not in any way take into consideration any potential effects of these chemicals on the reservoir formation fabrics. It is more often than not assumed that the interaction between chemical inhibitor species and sand materials is of no geomechanical significance. To investigate this, laboratory experiments were performed on Clashach cores representing clastic reservoir formation analogues. The experimental results show sand failure and release into the flow streams. Based on the experimental results conceptual physicochemical failure models are proposed for analyzing and describing the inhibitor-formation interaction.
