ABSTRACT:
A process for removing contaminating insoluble solids (e.g., rust, sand, scale, barite and drilling mud) from an aqueous fluid such as produced in well systems during cleaning operations before placement of packer brines. A small effective amount of an alcohol, and a surface active chemical aid, are thoroughly intermixed into the aqueous fluid. The concentration and/or composition of the alcohol and/or surface active chemical aid is adjusted to control agglomeration of the insoluble solids and then to settle, float or suspend same in the aqueous fluid. After the solids agglomerate, the solids are separated in a quiescent separation zone from the fluid by decantation, flotation or filtration, respectively.
