Carbo Ceramics




Higher performance in realistic conditions


Our wide range of high quality, high performance proppant is manufactured to have a low internal pellet porosity, so that it is strong and durable enough to withstand pressure cycling and avoid the creation of fines. That means the proppant will maintain more space to flow for the life of the well.

Industry-proven production performance

A study of production rates published by the Society of Petroleum Engineers has shown that the combination of the strength, uniform size and shape of engineered ceramic proppant provide higher production performance than other types of proppant (SPE 77675).
Numerous case studies and field trials have consistently demonstrated:
  • 20%+ increase in initial production
  • 20% + increase in estimated ultimate recovery (EUR)
  • Improved rates of return
  • Rapid payout on initial investment (often in just weeks or months)
  • Lower finding and development costs per BOE for E&P companies
  • Accelerated recovery times

Pioneering a New Method to Prevent Scale in Deep Water, High Pressure Reservoirs - A Gulf of Mexico Case Study

Production of hydrocarbons in deep water reservoirs involves the economical flow of hydrocarbons from the reservoir to the point of sale.

Ultra-High-Strength Proppant: An Update on Deepwater Applications in the Gulf of Mexico

With the advent of the development of lower Tertiary formations in the deepwater Gulf of Mexico, a gap in proppant technology was identified at the beginning of the decade. No existing conventional proppant could provide the required conductivity at the anticipated 15,000 psi (and higher) prevailing closure stress. To meet these challenges a new proppant was developed, with the goal of achieving twice the baseline conductivity of any conventional proppant at 20,000 psi. Learn More
