With the continuous decline in easily recoverable reserves of conventional oil and gas, the focus of oil and gas exploration and development has gradually shifted toward complex reservoirs, such as low-permeability, tight, high-temperature and high-pressure (HTHP), and strongly heterogeneous reservoirs. Such reservoirs...
Proppant flowback during the posthydraulic fracturing flowback stage can induce instability of the internal proppant support structure and conductivity degradation within fractures, which are critical factors constraining long-term stable production of low-permeability tight oil and gas reservoirs. However, existing st...
