Recommended Use
MACRO-FILL is ideally suited for solidification and stabilization of drilling fluids, wastewater, and sludge. MACRO-FILL is also a superior loss circulation material.
Characteristics
- Absorbs 300 times its own weight in water
- Can be added directly into drilling fluid
- Can be used with other lost circulation materials
- Expands approximately 5% in volume with maximum absorption
- Seals large and fine fractures and highly permeable and porous formations
- Will not harm pumping equipment
Mixing and Application
- Solidification Aid: Add 4-5 lbs (1.8-2.3 kg) per 100 gallons (378 liters) liquid
- Loss Circulation: Pre-mix 8-12 lbs (3.6-5.4 kg) in thinned fluid on surface and pump quickly to discrete depth via tremie pipe. Allow time for MACRO-FILL to expand before proceeding with drilling
Packaging
- 14 lb pail, 48 per pallet. All pallets are plastic-wrapped.
