Fed Primesol / Soltex

Fed Primesol / SoltexFED PRIME SOL shale inhibitor is a partially water-soluble, water-dispersible Sulfonated asphalt. It is used to aid in stabilizing shale sections, controlling solids dispersion and improving wallcake characteristics. It is also used as a supplemental high-temperature fluid-loss additive for water-base drilling fluid systemsPropertiesPhysical appearance- Fine black,/ gray powderSpecific gravity- 0.90-0.96 @ 77OFOdor- Mild sulfurSolubility - 71 % soluble in water @ 72OFpH - 9.12 (1% solution)ApplicationsFED PRIME SOL shale inhibitor is a sulfonated asphalt that can be used in most water-base muds. It is a free-flowing powder and can be added directly to the mud system through the mixing hopper. It is not necessary to premix the FED PRIME SOL agent with oil. It contains no surfactants or gilsonite compounds commonly found in low-cost shale-control products. FED PRIME SOL shale inhibitor's active ingredient is a true sulfonated asphalt prepared by the sulfur trioxide process. FED PRIME SOL additive will not interfere with well logging or formation analysis and does not produce a sheen on water. It inhibits shale hydration by bonding to the shale, not just coating the shale and clay particles  Normal concentrations of the FED PRIME SOl additive range from 3 to 6 lb/bbl fof  shale stabilizing control and 6 lb/bbl for high-temperature fluid-loss control. In water-base drilling fluid systems, FED PRIME SOL shale inhibitor additive exhibits the following characteristics:Stabilizes ShalesLower torque and dragReduces high- temperature fluid lossProduces thin-walled filtercakesImproves borehole stabilityAdvantagesEasy to handle and mixPlugs micro-fractures and seals shalesInhibits swelling and water-wetting of shalesReduces High-Temperature, High-Pressure (HTHP) fluid lossReduces torque and dragImproves filtercake qualityIncreases drilling fluid lubricityToxicity and HandlingBioassay information is available upon request Handle as an industrial chemical, wearing protective equipment and observing the precautions as described on the Material Safety Data Sheet (MSDS)Packaging and StorageFED PRIME SOL additive is packaged in 50-lb (22.7-kg) multiwall sacks; 50 sacks per shrink-wrapped pallet
