Brown Drispac

DrispacDrispac Polymers are high-quality polyanionic cellulose polymers. They are used for inhibition, water-loss control and viscosity in water-based muds. Drispac Polymer comes in two viscosity grades: regular (high viscosity) and Superlo Polymer (medium viscosity). Drispac Plus Polymer resists the formation of "fisheyes" even under the poorest mixing conditions. The highly dispersible Drispac Plus Polymer also comes in regular (high viscosity) and Superlo Polymer (medium viscosity) gradescostThe mixing efficiency of Drispac Plus Polymer reduces loss of active product and promotes lower mud and total well costs. The purity and assured high quality of the products are also strong contributors to lower overall mud cost. Mud TypesWater-based drilling and drill-in fluids, work over fluids and completion fluids of any salinity. Most efficient performance with calcium below 500 ppm. Slightly more polymer needed at higher calcium levels.HandlingFor specific instructions  on handling, refer to the MSDS.AdvantagesControls fluid lossPromotes fragile gelsInhibits hydratable, swelling shalesIncreases resistance of clay mud to contaminationNon-fermenting, no preservative neededGood thermal stabilityProduces thin, slick, tough filter cakeEnvironmentally compatibleRetards drilled solids build-upEliminates fisheyes in mudReduces friction and can reduce ECDWorks well on rigs with poor mixing facilitiesWorks well at any salinityApplicationFluid-loss controlInhibition/ encapsulationImproved filter cakestabilized rheologyReduced stuck pipe frequencyImproved hole cleaningMaterials Needed1 to 3 ppb (.3 to 9 kg/m3).75 to 3 ppb (2 to 9 kg/m3).5 ppb (2 kg/m3).5 to 1 ppb (2 to 3 kg/m3).5 to .75 ppb (1 to 2 kg/m3).5 to 3 ppb (2 to 9 kg/m3)
