Energy Resources Co. Inc. is currently operating a pilot polymer improved waterflood of the Storms Pool, a sandstone reservoir in the Illinois basin. During the second year of the project, progress was made in the laboratory work, field preparation, and computer simulation. Tasks II, VII, and IX, polymer selection, workovers, and model building were completed during 1979. The polymer selected is a xanthan type polysaccharide polymer. Other laboratory work included preliminary testing of biocides and oxygen scavengers. Development of the pilot area continued with the completion of the well workovers and the design and initiation of construction of the injection facility. Preliminary simulation was begun.
