Traditional fracture completion systems are often inefficient. They suffer from friction and pressure losses, large hydraulichorsepower requirements, premature openings with frequent screen-outs, and time-consuming multiple downhole operations.A monobore, or a single size ball system with disappearing seats, addresses many of the drawbacks to a traditional fracturedcompletion. By minimizing friction losses and pressure drops, monobore systems increase fracture effectiveness throughoutthe well while decreasing hydraulic horsepower requirements at the surface by up to 60%. The system delivers higher flowrates, lower stimulation pressures, reduced surface pressures, less equipment, smaller pad sizes and higher safety at less cost.In this paper the authors will describe the design and advantages of a monobore system with one size ball and disappearingseats.
