Brine completion and workover fluids. Part 2. Applications, calculations, and engineering guidelines
Heavy brine fluids have four main uses in the oil field: as a perforation fluid, gravel pack fluid, packer fluid, and workover fluid. A perforation fluid controls well pressures with a minimum of formation damage during perforation. A gravel pack fluid carries specially graded sand downhole where it is packed behind a producing screen. Packer fluids are placed between the production tubing and casing to maintain pressure control in the annulus. Fluids used during the reworking of a well after its initial completion are called workover fluids. The functions performed by these fluids include well killing, cleaning out a well by removing sand, metal cuttings, and other foreign objects, drilling into a new production zone, or plugging back to complete a more shallow zone. Millhone, in a recent article, summarized the selection and use of heavy brine and other completion and workover fluids.
