Correlation of the Flow of Flocon 4800 Biopolymer with Polymer Concentration and Rock Properties in Berea Sandstone
An experimental program was carried out to determine the mobility of Flocon 4800 biopolymer in Berea sandstone cores. Experimental work conducted at 25C included rocks with brine permeabilities ranging from 15.5 and to 848 and for polymer concentrations of 500–1500 ppm. Frontal advance rates varied from 0.1 ft/d to 117 ft/d. Flocon 4800 was found to follow a power-law model during flow through porous rock. Correlations were developed between polymer mobility, polymer concentration, and brine permeability of the rock after contact with polymer. Using these correlations, it is possible to estimate the mobility of Flocon 4800 in chemical flooding processes conducted in Berea core material within the range of polymer concentrations studied. Mathematical models derived from capillary bundle approaches and rheological parameters derived from steady shear measurements produced poor predictions of polymer mobility in Berea sandstone cores.
