Abstract

The poor proppant-carrying capacity of SC-CO2 fracturing (SCF) negates its potential advantages for the exploitation of deep unconventional gas reservoirs over traditional water-based fracturing (WBF). The low proppant concentration in SCF-created fractures leads to accelerated proppant damage behaviours under high in-situ stress, such as proppant crushing and proppant embedment, resulting in a reduction in hydrocarbon production. Micro-proppants (>100 nm,
