More than 200% increase in fracture conductivity and permeability was obtained when a new degradable fluid-loss-control additive was used in place of silica flour (SF) in 40-lbm crosslinked hydroxypropyl-guar (HPG) fracturing-fluid systems. The new additive, and organic acid particulate (OAP), slowly degraded into water-soluble monomeric units at temperatures {ge}150{degrees}F after fracture stimulation experiments. The high-acid-content degradation product then acted as an excellent HPG gel breaker and effectively cleaned the proppant packs. As a fluid-loss-control additive, the measured wall-building coefficients were as good as, or better than, those of SF in crosslinked-gel, linear-gel, and N{sub 2}-foam systems. This paper summarizes a 2-year study of the evaluation and application of this new product in fracturing-fluid systems.
