SOLUKLEEN® SYSTEM
DESCRIPTION

Solukleen additives are a blend of polymers, calcium lignosulfonate and specially sized oil-soluble resin particles. The two basic products, Solukleen which contains hydroxyethyl cellulose and Solukleen Ultra which is formulated with xanthan gum biopolymer are packaged in 25 lb sacks.

BASE FLUIDS

Solukleen functions in sea water or salt solutions such as potassium chloride, sodium chloride, and calcium chloride.

Solukleen Ultra features increased low shear rate viscosities in sea water, and brines such as potassium and sodium chloride.

APPLICATIONS

Solukleen and Solukleen Ultra are designed for use in completion and workover operations where oil-soluble resins are desired to minimize damage to productive formations. Applications may include the following operations:

  • Drilling into pay zone
  • Lost circulation pill
  • Underreaming
  • Washing sand
  • Milling

ADVANTAGES
  • May be used in a wide density range
  • Provides excellent fluid loss control in contrast to a clear brine
  • Can be used as a circulating fluid or as a lost circulation pill
  • Adaptable for a wide range of formation permeabilities with supplemental additions of Solubrige® Fine, Solubrige, Solubrige Mid and Solubrige Coarse
  • Essentially non-damaging to productive formations

MIXING INSTRUCTIONS

A clean, oil free pit equipped with a standard mud hopper and at least two sub-surface guns is suggested for mixing. Base fluid should be pre-treated with a defoamer (Defoam 2), and Solukleen and Solukleen Ultra should be mixed through a hopper at 3 - 5 minutes per sack. Circulate the pit at least 30 minutes before pumping downhole.

Care must be exercised to avoid contamination of the Solukleen and Solukleen Ultra with oil as this could adversely affect fluid performance.
