ZeroWash Tracers

ZeroWash® is a patented tracer material that eliminates wash-off and enables precise identification of proppant distribution and the analysis of fracture geometry resulting from fracture stimulation treatments. ZeroWash® is available in multiple isotopes, various mesh sizes, and densities.

SOLIDS ZERO WASH®   Intermediate strength ceramic bead embedded with Sc-46 (2.65 s.g.), Sb-124 (2.60 s.g.), or Ir-192 (2.64 s.g.). ZERO WASH® LD   Low density ceramic bead that is embedded with Sc-46 (1.29 s.g.), SB-124 (1.48 s.g.), or Ir-192 (1.34 s.g.). Designed for acidizing applications and low matrix injection rates. LIQUID ZERO WASH®   Resin micro spheres embedded with Sc-46 (2.29 s.g.) or Sb-124 (3.17 s.g.). Designed to emulate a fluid. Color: Various shades of gray. Mesh Size: 40/70 (will not flow through 20/40 or 12/20 sand pack). 16 through 80 mesh available. Crush Strength: >8000 psi   Color: Dark green to brown. Mesh Size: 40/70 (will not flow through 20/40 or 12/20 sand pack). 30 through 100 mesh available. Crush Strength: 1500-2000 psi Color: Ranges from light brown to white. Mesh Size: 8 - 200 microns, Average 75 microns Crush Strength: N/A * Custom irradiated High Volume Zero Wash® products are available by special order. LIQUIDS Most tracers can be made both oil and water soluble. Specific chemical additives can be used to balance the pH of the fluid to enhance adsorption on the formation or to reduce "plating out" on tubulars. It's not the completion design, it's how you SEE your completion.
