Carbo Ceramics



Protect your well in a simple treatment while you frac

The GUARD solution is developed by using ceramic proppant with engineered porosity that is infused with production chemicals. Each treatment incorporating GUARD can be designed to last for the effective life of the well. Our technologies significantly reduce production maintenance requirements and costs, avoid workovers and eliminate the potential for catastrophic production system failures.

SCALEGUARD scale-inhibiting technology

Watch this video to see how SCALEGUARD technology is placed throughout the entire fracture as part of the standard fracturing process. providing long term protection after just one application. 

More efficient than alternative treatments

Our unique GUARD technology outperforms other production assurance treatments which can be inefficient, expensive and required to be repeated due to their short effective periods.

GUARD treatments:

  • Controlled release technology significantly lengthens treatment life and reduces initial inhibitor washout
  • Engineered ceramic proppant that provides effective chemical delivery, high fracture conductivity and strength
  • Liquid inhibitor added to frac fluid is short-lived and inefficient due to the large volume of chemicals required
  • Periodic squeezes are short-lived and must be routinely repeated, incurring ongoing operational expenditure
  • Other particulate chemical carriers added during frac can impair conductivity and can be short-lived

Effective Scale Prevention Using Chemically Infused Proppant - A Uinta Basin Case History

Scale deposition down hole is a well-known and common production problem throughout the industry. Successful treatment of scale where it is first deposited near wellbore can be challenging in many cases, and sometimes impossible in others. Learn More

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

A Novel Technique for Determining Screen Failure in Offshore Wells: A GOM Case History

Offshore completions in the Gulf of Mexico (GOM) must typically address sand control. Our industry has made significant progress with respect to sand control equipment and implementation. Learn More

Novel Proppant Surface Treatment Yields Enhanced Multiphase Flow Performance and Improved Hydraulic Fracture Clean-Up

This paper describes the development and testing of a new proppant designed to exhibit a neutrally wet surface. The modified surface does not have a preferential affinity for oil, gas, or water and therefore will not promote the preferential entrapment of any phase within the proppant pack. Learn More

Can Proppants Do More Than Hold The Fracture Open?

In the 1940’s experimental fracture treatments were performed without proppant. However in most formations unpropped fractures heal quickly with no sustained benefit, and in 1947 river sand was introduced as proppant. Learn More

Controlling Proppant Wettability Leads to Increase Flowback Recovery and Flow in Frac-Packs

Recovery of frac-pack fluids is often poor in offshore operations. Large amounts of stimulation fluids left in the fracture may leak-off into the porous formation or block part of the proppant pack thus impairing hydrocarbon production. Learn More

A Novel Technology for Providing Long Term Scale Prevention in an Alaskan North Slope Waterflood

Most North Slope Alaska oilfields undergo waterflood for pressure maintenance and improved oil recovery. Both recycled produced water, as well as treated seawater are injected into the reservoir which then mixes with connate water in the formation. Learn More

Sieve Distribution vs Sand Retention: The Impact of Mono-Sieved Gravel on Sand Control

Traditional sand control sizing has typically been based on "standard", wide-sieve gravel distributions (i.e. 20/40, 16/30, etc). Historic sand retention testing has therefore been limited to these standard gravel (i.e. proppant) sizes. Learn More

Prevention of Halite Formation and Deposition in Horizontal Wellbores: A Multi Basin Developmental Study

Halite scale is a wide spread problem throughout several basins in the United States. This scale can form in surface equipment, downhole tubulars as well as affecting production. Traditional remediation of halite can be accomplished by dissolving the scale in fresh water as well as recycled water. Learn More
