The widespread technologies of bottomhole treatment in oil and gas wells within the well’s effective range includes acid treatment, acoustic treatment (wave methods) and many other waves of production enhancement.

The main disadvantage typical of these methods is that physical and chemical impact is produced within the range of the well itself without touching the adjacent sections of oil formation system. Hence, the investigated and approved hydrocarbon reserves in these sections remain intact, though they are included in the calculations of estimated oil and gas reserves. Clearly, this circumstance curbs the amount of recoverable reserves at the final production stage. It happens, because wells for oil and gas stimulation are usually selected in the rectilinear or circumference segment of the structural map or filed development map.
