CoreAqueous is a combination of surfactant/solvent product for use as a casing cleaner in both oil-based and water-based drilling fluid displacements. It can provide a “one–pit, one-pill” system meaning less pit space is required. It can also be used as an effective “lead pill” during water-based and some oil-based mud displacements or as first aqueous pill after gross oil-based mud removal with a CoreClean pill.
