Flocon biopolymer

The correlation developed between the mobility of Flocon biopolymer and brine permeability following polymer contact in Berea cores has implications for mobility control in chemical flooding processes. Because the mobility of a polymer solution is not a linear function of the rock permeability, a polymer solution that provides mobility control in one rock may not maintain mobility control in another rock of the same type which has a significantly lower permeability. 

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... 

Flow experiments were conducted using the Pfizer Flocon 4800 series biopolymer. This polymer was selected because initial experiments indicated that permeability reduction due to polymer retention could be held to 15-20% by carefully filtering the polymer solutions. This allowed study of the effects of polymer concentration on polymer flow without...
