摘要：
Apparatuses and methods for improving the reliability of pinpoint stimulation operations is disclosed. A pinpoint stimulation improvement apparatus is disclosed which includes a hold down device, at least one flow reducer coupled to the hold down device, and a jetting tool coupled to the flow reducer. The flow reducer is positioned downstream from the jetting tool. A fluid flowing through the jetting tool passes through the flow reducer and forms a sand plug downstream from the pinpoint stimulation improvement apparatus.
