PERFFLOW Systems Application
Three product compositions are available to prepare PERFFLOW fluids: W-307, W-306, and
PERFFLOW DIF. W-307 is used in preparing PERFFLOW fluids utilizing sodium chloride or
potassium chloride brines. W-306 and PERFFLOW DIF are used in preparing PERFFLOW fluids
utilizing potassium chloride, sodium chloride, calcium chloride, calcium bromide and zinc
bromide, formate brines or mixtures of these brines.
Standard Systems Formulation
LOW-DENSITY PERFFLOW Systems (9.2- 10.5 ppg)
1. Preferred Barrel Formulation:
• 1 PERFFLOW DIF (55 lb/25 kg bag) plus 0.94 bbl of brine
• 0.94 bbl of brine includes 2% to 4% KCl
• 1 gal/100 bbls X-CIDE ® 102 (25% by volume glutaraldehyde)
2. Optional Barrel Formulation:
• W-306 (5 or 55 gallon) @ 2.00 gpb to YP = 20 or W-307 (5 or 55 gallon) @ 2.50 gpb to
YP = 20
• 1 MIL-CARB TM (50 lb bag)
• Final volume contains 2% to 4% KCl; brine volume to 1 bbl
• 1 gal/100 bbls X-CIDE 102 (25% by volume glutaraldehyde)
HIGH-DENISTY PERFFLOW Systems ( > 10.5 ppg )
1. Preferred Barrel Formulation:
• 1 PERFFLOW DIF (55 lb/25 kg bag) YP = 20
• 2 to 3 ppb Magnesium Oxide to buffer pH = 8.0
