Abstract: 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.

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.

Abstract: Characteristics of a reservoir may be used to generate multiple models of the reservoir with hydraulic fractures. Simulated configurations of the hydraulic fractures in the models may be used to select one or more of the models as representative model(s) for the reservoir. The representative model(s) may be used in development of the reservoir. Hydraulic fracturing may increase productivity at shale and tight rock reservoir by creating more effective flow paths to production.

Abstract: A method for evaluating multiple wells using water chemistry analysis may include testing a parameter associated with a first sample obtained from each of the wells over a period of time prior to implementing the field operation of the well. The method may also include generating a baseline of the parameter associated with the first samples for each of the wells. The method may further include testing the parameter associated with second samples obtained from each of the wells during the field operation of the well. The method may also include determining a difference in the parameter between the baseline and results of testing the second samples for at least one of the wells, where the difference exceeds a threshold parameter value for the parameter, and where the difference includes a characterization of water saturation.

Abstract: Methods, systems, and non-transitory computer readable media for estimating well interference on a target well from other potential wells in a subsurface volume of interest are disclosed. Exemplary implementations may include: obtaining well implementation data for the target well and the other potential wells; obtaining estimated reservoir volumes as a function of position; generating well overlap between the target well and the other potential wells; generating extraction interference probabilities; generating a representation of a well layout as a function of position in the subsurface volume of interest; and displaying the representation.
