... Abstract Non-aqueous gravel pack carrier fluids (GPCF) have been introduced into the industry to eliminate the risks associated with the water-based carrier fluids in the presence of reactive shale interbeds in the reservoir. However, non-aqueous GPCF pose a significant barrier to the effective...

It became natural to evaluate this fluid also as a carrier fluid for the gravel, thus mitigating the risk of losses. Due to small margin between pore pressure and fracture gradient, the gravel pumping...
