REMOVAL OF METALS AND CATIONS THEREOF FROM WATER-BASED FLUIDS

摘要

At least one solid may be separated from a water-based fluid by flowing the water-based fluid through a filter media in combination with filtration equipment, such as a filter press. In a non-limiting embodiment, the filter media may be or include, but is not limited to, diatomaceous earth and at least one alkaline earth metal(s). The solid(s) may be or include a metal, such as but not limited to zinc, iron, manganese, mercury, nickel, cations thereof, and combinations thereof. In a non-limiting embodiment, the water-based fluid may be or include a production fluid, a drilling fluid, a drill-in fluid, a completions fluid, a fracturing fluid, a servicing fluid, a stimulation fluid, a treating fluid, and combinations thereof.

主权项

1. A method for removing at least one solid from a water-based fluid comprising:
flowing a water-based fluid through filtration equipment at least a first time where the filtration equipment comprises a filter media, and the filter media in turn comprises an effective amount of diatomaceous earth and an effective amount of at least one alkaline earth metal or compound thereof to at least partially remove the at least one solid from the water-based fluid; and at least partially separating the solid(s) from the water-based fluid to form a filtered water-based fluid.
