Russian Well Service Company “HION” provides Pulse-Jet Technology and Services for enhanced oil recovery, including treatment of wells immediately after drilling. The technology is based on the environmentally friendly combined multifunctional well treatment by a vibrant pulse-jet draining and flushing, and vacuum cleansing of the around the well bore zone, as well as by a wave influence on the productive layer. The principle difference from other methods of wave influence is that this Pulse-Jet Technology produces the depression waves of wide range and power in the infra-frequent diapason, which significantly increases the radius of treatment and oil extraction capacity from the productive layers. The intensive combined, complex treatment is produced by several original installations – major component modules, integrated into one effective Pulse-Jet Complex ISK-1: hydraulic generator-amplifier and two vacuum (implosion) generators, one of which is installed on the surface the other – inside the well, as well as by other units providing the synchronized processing of the around thye well zone.
