Vertechs VD series degradable frac diversion system is designed for diverting fluids during stimulation treatment. Naturally, the fluids will reach the zone with lowest rock stress at the early stage of a fracture treatment. By utilizing VDP and VDB, the path to lowest stress zone will be sealed temporarily and withstanding high differential pressure, the fluids is then selectively diverted to new zones with higher rock stress. This deployment of the VD series alternatives, utilizing the engineered particles or sized diverter ball provides a design concept tailored for specific reservoir conditions. This unique and flexible strategy achieves a more uniform stimulation result across the entire payzone.
