背景

The treatment success rate of sandstone acidizing is relatively low, estimated between 50% to 60%. Losses not only affect the treatment and operation costs, but they also compromise well productivity because of the potential formation damage generated by the treatment. PDVSA needed to minimize the risk of treatment failure, reduce the required treatment volume, and decrease operating time, cost, and logistics in comparison with conventional stimulation systems.
