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.

Abstract: A closed-loop automation tool models individual wells in a field and connections between the wells in the field. Field measurements are used to validate and calibrate the models. The tool updates values of operation parameters of the wells, such as gas lift gas rate for gas lift wells and electrical submersible pump frequency for electrical submersible pump wells. The updated values are used to increase the efficiency of the wells and increase production with minimum human intervention.
