CARBOAIR for gravel pack applications

CARBOAIR high-transport, ultra low-density ceramic proppant technology enables operators to efficiently create a high-quality gravel pack at low fluid viscosity and pump rates.


  • Cased hole and open hole gravel packing in vertical, deviated and horizontal wells
  • Gravel packing in low frac gradient and narrow frac formation pressure window environments
  • Multi-path screen horizontal open hole gravel pack
  • Gravel pack applications when using erosion-sensitive completion hardware

Efficient gravel pack placement at low pumping pressure

The excellent proppant transport characteristics of CARBOAIR technology enables lower fluid viscosity and pump rates to be used. This allows efficient pack placement and the full packing of the annulus while avoiding fracturing the formation.
The reduced fluid viscosity and pump rates are critical in wells with low frac pressure and/or a low working window between frac pressure and formation pressure.  These conditions are typical in many shallow unconsolidated formations that require gravel packing for sand control.

Consistent sand retention performance

CARBOAIR technology has a consistent mesh size distribution and mean particle density (MPD) that delivers consistent sand retention performance.

High permeability for minimal pressure drop

Under radial flow conditions in a gravel pack completion where all production is passing through the pack, and perforation tunnels in cased hole, any impairment to pack permeability has a significant negative impact on well productivity. Gravel packing with CARBOAIR technology has a high completion efficiency as it results in a minimal completion skin that avoids any impairment to well productivity.

  • Available in 40/70, 30/50 and 20/40 mesh sizes


  • Minimal completion skin for increased well productivity
  • Preserves formation permeability and proppant pack conductivity
  • Enhanced proppant transport for efficient gravel pack placement
  • Enables low fluid viscosity and pump rates to be used
  • Avoids formation fracturing during gravel pack operations

Ideal for Alpha-Beta gravel packing in operations

The Alpha-Beta wave technique is typical in gravel pack operations with straight or slick water in horizontal or highly deviated wells. In these operations, the pump rate, carrier fluid viscosity and proppant density determine the height of the alpha wave and pressure applied to the formation through the treatment.
As an ultra-low density ceramic proppant, CARBOAIR technology lowers the height of the alpha wave leaving more space above it to place the beta wave. This reduces the pressure, preventing fracturing the formation.
