KRYPTOSPHERE LD ultra-conductive, low-density ceramic proppant

KRYPTOSPHERE LD ultra-conductive, low-density ceramic proppant technology significantly exceeds the conductivity, compressive strength and durability of existing low-density proppant.
In addition, KRYPTOSPHERE LD technology provides comparable and, in many cases, higher conductivity than intermediate-density and bauxite ceramics while delivering improved proppant transport and increased propped fracture volume.
The higher flow rates and larger propped volume increases recovery and return on investment, thereby lowering finding and development costs per barrel of oil equivalent.


  • Precision-engineered, strong, durable, round, mono-sized and smoother proppant grains
  • Single-mesh-sized product manufactured to any size required to suit well conditions
  • Significantly higher baseline conductivity compared to typical intermediate and low-density ceramic proppant
  • Extraordinary strength and durability compared to standard low-density ceramic proppant
  • Excellent roundness, sphericity and smoothness for less erosivity


  • Creates a frac with more uniform pore throats and more space for hydrocarbon flow
  • Maintains the highest flow rates and levels of conductivity for the productive life of the frac
  • Reduces flow path tortuosity to reduce non-Darcy impacts and improve overall conductivity
  • Improved proppant transport and higher propped fracture volume compared to intermediate-density proppant
  • Significantly less erosion during pumping and minimizes wear-and tear on equipment and tools

A step-change in performance

KRYPTOSPHERE LD technology creates more space for hydrocarbon flow which results in the highest levels of production and recovery across the entire range of low and high stress conditions.

The significantly higher baseline conductivity compared to typical intermediate- and low-density ceramic proppant maintains the highest flow rates and extends the productive life of the frac.

Sustains conductivity after stress-cycling

KRYPTOSPHERE LD technology has a high crush-resistance and withstands stress-cycling to ensure that fracture conductivity, integrity and connectivity are sustained long-term to optimize production.

Lower beta factor and pressure drop

The spherical, smooth and uniform size characteristics of KRYPTOSPHERE LD technology creates a frac with more uniform flow paths. The reduced flow path tortuosity minimizes the pressure drop due to non-Darcy flow effects across the fracture which further enhances overall conductivity, flow rates and ultimate recovery.

Exceptional microstructure for increased strength and durability

KRYPTOSPHERE LD technology has an exceptionally low and uniformly distributed internal porosity which creates a proppant with extraordinary compressive strength and durability.

Standard low-density ceramic proppant

High internal porosity with irregular distribution dramatically reduces strength leading to the creation of fines that rapidly reduce conductivity and production.
