Study of granular gels properties to control the development of oil fields. Ovchinnikova S. V., Ali G. H. The ultimate goal of this work was to develop a method to be used in mature oil fields aimed at plugging the highpermeability water flooded layers with further displacement of oil from the low-permeable interlayers and decreasing the water production. The experimental studies were carried out to assess the influence of different types of PPG gels (30 mesh and 40 mesh) on the injectivity of low permeable rock samples. In this study the permeability of the rock samples was measured before and after the gels injection. The injection of gels was run at different pressures and various concentrations of the brine. Additionally, the influence of the brine concentration on the gels swelling and strength was studied. The gel particle size is in the ranged from 30 to 80 mesh.
