摘要： 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.

摘要： 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.

摘要： A method for identifying an unidentified subterranean sample may include comparing values for a subset of fluid chemistry parameters associated with the unidentified subterranean sample to values of corresponding fluid chemistry parameters associated with a plurality of identified subterranean samples. The method may also include determining, based on comparing the values for the subset of fluid chemistry parameters associated with the unidentified subterranean sample to the values of the corresponding fluid chemistry parameters associated with the plurality of identified subterranean samples, an estimated value for a target parameter associated with the unidentified subterranean sample. The method may further include recategorizing the unidentified subterranean sample as being among the plurality of identified subterranean samples based on the estimated value for the target parameter.

摘要： 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.

摘要： A method for enhancing water chemistry at a surface for improved well performance may include testing water at the surface to identify a pH level of the water, a type of solid-generating component in the water, and an amount of a solid-generating component in the water. The method may also include identifying a type and an amount of an additive based on identifying the type and the amount of the solid-generating component, where the additive is configured to generate a solid when mixed with the water. The method may further include mixing the water and an additive at the surface to generate the solid and enhanced water, where the solid comprises at least some of the solid-generating components of the water. The enhanced water may be usable for a field operation to cause the improved well performance, and the solid may be removable from the enhanced water at the surface.

摘要： A method of improving a field operation that comprises a gas injection may include assessing a plurality of potential injection gases against a plurality of values of a plurality of parameters associated with a plurality of samples, where each of the plurality of potential injection gases comprises an acidic component, and where the plurality of parameters comprises fluid chemistry parameters and rock properties. The method may also include determining a proposed injection gas from among the plurality of potential injection gases for the field operation that comprises the gas injection to be performed using a first wellbore in fluidic communication with a first subterranean formation, a second wellbore in fluidic communication with the first subterranean formation, a third wellbore in fluidic communication with a second subterranean formation, or any combination thereof.
