Early fracture treatments in the AWP (Olmos) field utilized over 1,000,000 lbs. of 20/40 mesh Ottawa sand. While production results were good, mechanical problems and economic factors necessitated alternative treatments. Smaller volume schedules were tried, but the resulting production lagged the larger jobs. Recently, treatments designed with resin coated sand (RCS) improved well performance. The stronger RCS maintains better conductivity at lower proppant concentrations with resultant good production response at a lower total cost. As an additional benefit, the curable RCS bonds together to eliminate proppant flowback.
