Sand Seal Fine and Coarse

  • Effective in wide range of loss zones
  • Forms a light, strong seal under most conditions
  • Reduces lost rig time
  • Seals under high and low differential pressure

Sand Seal is an engineered blend of particles which:

  • Contains high strength granules, flakes and fibers with a definite particle size distribution.
  • Seals effectively under both high and low differential pressure conditions.
  • Is equally effective in unconsolidated formations and fractures or vugs in hard formations.

Modicide 340 is the recommended biocide which protects the Sand Seal from the decomposition during drilling operations.

Sand Seal is available in two grinds:

Coarse is used to seal large fractures and highly permeable formations. This grind is a highy effective particulate lost circulation material which can be pumped easily through large jets or open watercourse bits.

Fine, where seepage losses are a problem. Fine is most effective in sealing fine fractures and porous formations. Due to its composition of fine fibers and granules, this grind of product is an ideal preventative material for these situations
