CARBO Ceramics

Neutral wettability relative permeability modification technology – RPM relative permeability modification technology is engineered to alter the wettability of proppant to neutral, preventing the retention of water-based fluid in the proppant pack. It increases the effective fracture length, conductivity, and permeability of the pack to hydrocarbons, leading to higher production and increased ultimate recovery. RPM is a surface modification coating applied during manufacturing and available as a flow enhancement to any CARBO ceramic proppant. Features: surface modification that alters the wettability of treated proppant to neutral with a contact angle ~90°; coating stable up to 400°F (205°C), suitable for most wells; treated proppant compatible with fracturing fluids; available as a flow enhancement to any CARBO ceramic proppant. Benefits: increases oil and gas production; improves water-based fracture fluid clean-up after stimulation; prevents water-based fluids from becoming trapped in pack pore throats; increases effective fracture length, conductivity, and permeability; reduces pressure drop due to multiphase flow effects; virtually eliminates capillary forces in the proppant pack; increases condensate production to help combat condensate banking.

Proppant-delivered scale-inhibiting technology – SCALEGUARD proppant-delivered scale-inhibiting technology is a porous ceramic proppant engineered with an innovative controlled-release technology and infused with scale-inhibiting chemicals. It is placed throughout the entire fracture as part of the standard fracturing process, and a single treatment can be designed to safeguard the entire production system-from the fracture through the wellbore to the surface processing equipment-for the life of the well. Its controlled-release technology ensures scale-generating water is inhibited at a designed rate so levels remain above the minimum inhibitor concentration (MIC)-field proven to maintain above the MIC for 500+ days. It serves as both a scale inhibitor and proppant with no impact on fracture conductivity, and is part of the GUARD proppant-delivered production assurance technology portfolio.
