Scleroglucan is an attractive biopolymer for EOR thanks to its resistance to shear, salinity, temperature and to its low environmental impact. However, previous scleroglucan grades suffered from a lack of filterability because of polymer aggregates and broth residues coming from their synthesis. A new EOR-grade scleroglucan has been submitted to lab experiments. Care must be taken to properly solubilize this polymer in powder form. The injectivity of scleroglucan solutions into a low permeability limestone at residual oil saturation is good and adsorption of the macromolecule on the rock is low. Thus the last technical barriers for scleroglucan to be used as a powerful flooding agent have been removed. Moreover, it can be a potential conformance control agent in low permeability reservoirs.
