Completion Fluid Additives

are solids-free liquids used to "complete" an oil or gas well. These fluid types are placed in the well to facilitate final operations prior to initiation of production. The fluid is meant to control a well should downhole hardware fail, without damaging the producing formation or completion components. Completion fluids are typically brines (chlorides, bromides and formates). The fluid should be chemically compatible with the reservoir formation and fluids, and is typically filtered to a high degree to avoid introducing solids to the near-wellbore area.
