ABSTRACT:
A low residue well treatment fluid comprises: an aqueous solvent; a gelling agent comprising one or more modified polysaccharides, the modified polysaccharides having hydrophilic groups; and a crosslinking composition. The fluid may optionally further comprise a gel breaker, a buffer and/or a proppant. The fluids generate no or minimal residue upon being broken, and are particularly useful in well fracturing operations.
