    Abstract: 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.

    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: 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.

    Abstract: Elemental mercury is removed from a gas by contacting it with a halogen dissolved in an organic solvent. The mercury accumulates in the organic solvent and can be removed by extraction with an aqueous solution with a complexing agent, by adsorption, and by combinations. The absorption process can also operate by use of a series of absorbers which have successively higher concentrations of halogen in the solution and which successively remove more the mercury from the gas. A portion of the solvent in the last absorber can be cascaded to the previous absorber in the series. In one embodiment, the process is carried out at a temperature of absorber at less than or equal to 28° C. above the higher of the water dew in point and the hydrocarbon dew point. The mercury waste from the process is produced as either an aqueous solution or a small volume of mercuric sulfide.

    Abstract translation: 通过使其与溶解在有机溶剂中的卤素接触，从气体中除去元素汞。 汞积聚在有机溶剂中，可以通过用络合剂的水溶液萃取，通过吸附和组合除去。 吸收过程也可以通过使用一系列在溶液中具有连续较高浓度的卤素并且连续地从气体中除去更多汞的吸收剂来进行操作。 最后一个吸收器中的溶剂的一部分可以串联到先前的吸收体。 在一个实施方案中，该方法在低于或等于28℃的吸收剂的温度下进行，高于高于水露点和烃露点。 来自该方法的汞废物以水溶液或少量硫化汞的形式产生。

    Abstract: 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.
