Formation pressure reductions impact filtration and capacitive rock properties
Oilfield and laboratory studies have identified unrecoverable deformations which exist in formation pressure reduction zones at numerous fields in Western Siberia. Such deformations are driven by loads and time of exposure. In addition to lower production rates, these deformations tend to reduce the overall oil recovery.
