Abstract
Drilling fluid solids (mud, solids and oil) can be removed from completion/packer brines in a well system by employing a small effective amount of an aliphatic alcohol and a surface active chemical aid mixed with the contaminated brines. Under some conditions, the brine can become recontaminated in a well with a small amount of solids which settle to the production zone in the well bore. These settled solids obscure acoustic logging and plug perforations into the production zone. These settled solids are removed by spotting a chemical aid in selected volume and concentration. These solids now become buoyant and rise upwardly in the well bore leaving in the well the production zone with clean solids-free brine. As a result, the entire volume of brine does not require treatment.
