Abstract: A hybrid modeling approach incorporates both physics-based reservoir modeling and machine learning technique to capture dynamic behavior of unconventional wells. Shut-in bottom hole pressure for unconventional wells are simulated for use as proxy for reservoir pressure in unconventional reservoirs. Production parameters for unconventional wells (e.g., gas/oil ratio, water cut, flowing bottom hole pressure, shut-in bottom hole pressure, productivity index) are determined for use in controlling the operations of unconventional wells.

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.
