DESCRIPTION
The Hysal System utilizes either sized
sodium chloride or calcium carbonate bridging particles for lost
circulation pill applications requiring fluid densities above 12.5
lb/gal. The Hysal System is composed of
four basic products, Hysal SF, Hysal HD
and Hysal HT with sodium chloride bridging
solids, and Hysal C with calcium
carbonate.
The Hysal System can be used for:
- Lost circulation pills
- Perforating fluid loss pills
- Pre/post gravel pack fluid loss pills
Hysal products may be formulated in
calcium chloride, calcium bromide and/or zinc bromide mixtures.
Hysal is packaged in 50 lb or 25 kg
sacks.
FEATURES
- Applicable across a broad range of fluid densities
- Provides effective bridging and temporary plugging of
productive formations and flows easily through wire-wrapped
production or tell-tale screens during displacement
- Can be used to seal inside a completion screen to prevent
losses with the addition of larger bridging particles
- Incorporates a unique combination of derivatized starch,
buffer, and bridging solids which provides excellent filtration
control up to 250°F
