Why Sodium Methallyl Sulfonate Can Be Effectively Injected Without Plugging in the Middle and Late Stages of Low-Permeability Reservoirs
In the middle and late stages of low-permeability reservoirs, the pore structure is complex, with narrow throats and strong heterogeneity, making effective water injection and profile control extremely challenging. However, Sodium methallyl sulfonate (SMAS) can still be effectively injected without causing reservoir plugging, which is mainly attributed to its unique Read more
