A new proppant

By Chemical Engineering |

Last month, Carbo Ceramics Inc. (Houston; www.carboceramics.com) introduced KryptoSphere, an ultra-conductive, high-strength proppant technology designed to maximize and sustain hydrocarbon flow at high closure stresses for the life of the well. Developed in response to a request from a major operator in the U.S. Gulf of Mexico, KryptoSphere is said to deliver twice the baseline conductivity of bauxite-based, high-strength proppants at 22,000 psi closure stresses, according to the company. The improved performance is due to the microstructure of the new proppant, which is more spherical, more uniform and smoother than other proppants. This property creates more space in the fracture for hydrocarbon flow as well as a more uniform flow path, says the company.
