Abstract
A method for evaluating and optimizing scale management at a subsurface for improved well performance may include performing multiple first tests, where each first test combines a first fluid with a second fluid, wherein the first fluid comprises a concentration of a scale inhibitor and a chemistry of additional fluid components. The method may also include identifying an optimal mixture of the first fluid among the first tests, where the optimal mixture comprises a minimum concentration of the scale inhibitor that reduces scale deposition. The method may further include performing a second test that combines the first fluid with the scale inhibitor, the second fluid, and rock. The method may also include evaluating a concentration of the scale inhibitor in aqueous phase after a period of time after initiating the second test. The method may further include identifying a target fluid for use in a field operation at the subsurface.
