Sanheal Pill is a blend of hydroxyethyl cellulose (HEC) with other polymers and sized calcium carbonates, stabilized to prevent degradation by bacteria and temperature. All components are soluble in 15% hydrochloric acid. Sanheal Pill is packaged in 50 lb or 25 kg sacks.
Sanheal Pill is used as a pill for spotting across lost circulation zones. The typical concentration of Sanheal Pill is 50 lb/bbl of base fluid. The volume of the pill will vary according to the length of the lost circulation zone, severity of lost circulation, and hole size, but should be twice the volume required to cover the problem zone.
Severe or complete lost circulation may require the addition of larger bridging particles. Sluggits (bridging carbonates) with a fine to coarse particle distribution may be added in concentrations of 10 to 75 lb/bbl.
