OSS Pill additives are a blend of polymers and specially sized oil-soluble resin particles. The two basic products, OSS Pill which contains hydroxyethyl cellulose and OSS Pill Ultra which is formulated with xanthan gum biopolymer are packaged in 25 lb sacks.
OSS Pill functions in sea water or salt solutions such as potassium chloride, sodium chloride, and calcium chloride.
OSS Pill Ultra features increased low shear rate viscosities in sea water, and brines such as potassium and sodium chloride.
OSS Pill and OSS Pill Ultra are designed for use in completion and workover operations where oil-soluble resins are desired to minimize damage to productive formations. Applications include the following:
A clean, oil free pit equipped with a standard mud hopper and at least two subsurface guns is suggested for mixing. Base fluid should be pre-treated with a defoamer (Defoam 2), and OSS Pill and OSS Pill Ultra should be mixed through a hopper at 3 - 5 minutes per sack. Circulate pit at least 30 minutes before pumping downhole. OSS Pill and OSS Pill Ultra are normally used at a concentration of 25 - 30 lb/bbl with 25 lb/bbl of Solubrige.
Care must be exercised to avoid contamination of the OSS Pill and OSS Pill Ultra with oil as this could adversely affect fluid performance.
