... laboratory study to identify the appropriate gel formulation (e.g. polymer, polymer concentration and cross linker ratio) at reservoir conditions. The recommended gel system developed was validated by a core flood before field implementation. The first gel treatment was implemented in July 2010, followed...

... wells production performance after a polymer gel treatment for water shutoff. A total sample of 31 historical applications of gel treatments were used for training and validating the proposed networks. Historical applications gathered include different well and reservoir types, which make the model...

... resistance factor (RRF) is determined to water and oil 6 . The permeability to the specific phases, before and after the treatment, should be known. The permeability reduction is the ratio of the effective permeability before and after the gel treatment. (1) R R F = K b e f o r e...

... ABSTRACT Previously published field results were examined to determine if they reveal usable guidelines for the selection of wells as candidates for gel treatments. Views of seven gel vendors and experts from eight major oil companies were also examined concerning the selection...
