Currently, over 90 % of oil is recovered through water injection into reservoir formations. However, this technique often accelerates uneven oil distribution both vertically and laterally within the reservoir, a challenge especially pronounced in highly heterogeneous formations. In such cases, high-permeability layers become water-saturated more quickly, leading to a temporary increase in oil production, placing additional demands on the reservoir pressure maintenance system, impacting oil collection and processing operations, and causing other operational complications.
Many oil fields in Azerbaijan are now in their late stages of development, characterized by high water content in produced fluids, largely corresponding to hard-to-recover reserves. This situation diminishes the effectiveness of strategies aimed at enhancing oil recovery and controlling water influx. Consequently, improving the efficiency of complex reservoir exploitation by reducing produced water and partially increasing oil recovery has become increasingly important.
Approaches to achieve these goals include lowering water content in well production, balancing the pressure in water-displaced zones, isolating internally flushed sections, and mobilizing unswept, oil-rich areas. These objectives can be addressed through the use of chemical reagents or their derivatives.
