Abstract

A process for preparing an oil recovery mobility control solution having activity enhancement of greater than 15% and a filter ratio of less than 3 through a Millipore filter with a pore size of 1.2 microns comprises heating an aqueous solution of Xanthomonas biopolymer at an equivalent xanthan concentration of 0.05 to 2.0% and a salt content of less than 0.2% for a period of from about 2 to 60 minutes at a temperature of about 60-98 DEG C, and when the equivalent xanthan concentration exceeds 3000 ppm diluting the solution to an equivalent xanthan concentration of from about 100 to 3000 ppm. Also disclosed is such a process which comprises the steps of: (a) diluting a whole Xanthomonas fermentation broth to an equivalent xanthan concentration of 0.15-1.5% with water having a salt content of less than 0.2%; (b) heating said broth for a period of from about 2 to 60 minutes at a temperature of about 77-98 DEG C; and (c) filtering said broth to yield a filtrate with activity enhancement of greater than 15% and a filter ratio of less than 3 through a Millipore filter with a pore size of 1.2 microns. e [GB2036056A]
