Clarification of high density brine fluids

A process for clarifying a high density brine based fluid involves flocculating suspended solids from the spent brine based fluid, separating flocculated solids from the fluid and filtering the fluid. Suspended solids are flocculated using a particulate filter aid such as a diatomaceous earth and a...

Zusammenfassung:	A process for clarifying a high density brine based fluid involves flocculating suspended solids from the spent brine based fluid, separating flocculated solids from the fluid and filtering the fluid. Suspended solids are flocculated using a particulate filter aid such as a diatomaceous earth and a water-soluble polymer. Clarified brines can be reused in well drilling and completion fluid applications.
