A method for evaluating a fluid to reduce a deposition of a solid within a fractured subterranean formation may include obtaining information about materials inside of a testing vessel, where the materials are designed to be representative of the fractured subterranean formation. The method may also include providing a fluid that flows through the materials inside the testing vessel for a period of time, where the testing vessel is subjected to conditions designed to be representative of downhole conditions of the fractured subterranean formation. The method may also include evaluating the material to characterize the deposition of the solid on at least some of the materials after the period of time.

Assessing and reducing deposition of scales and other solids

A method for evaluating a chemical treatment at a subsurface for improved well performance may include obtaining information about a post-reaction fluid that results from a fluid flowing through a testing vessel for a period of time, where the testing vessel comprises a plurality of materials, where the plurality of materials is designed to be representative of the subsurface, and where the plurality of materials comprises rock and proppant. The method may also include performing, using the information, a compatibility test on the post-reaction fluid and the plurality of materials after the period of time. The method may further include evaluating, after performing the compatibility test, an effect of the post-reaction fluid on the plurality of materials.

Optimizing chemical treatment at the subsurface for improved well performance

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.
