Goals: location of weakly drainable (by-passed) reserves, increase of oil production, optimization of field costs. It has been in use in Russia since midst of 1990 with average annual surplus oil production 100-300 thousand tons. | |

Goals: integration of stratum qualities and new opportunities of EOR technologies. Combination of vertical and horizontal displacement of oil. Planning of development with optimal ORR. Successfully applied in the oilfields of Western Siberia. | |

This technology is based on inflation of gas into the stratum and its further transformation into efficient displacing agents due to low temperature intra-stratum oxidizing processes. Excellent field results were achieved in the USA, Ukraine and Russia. | |

This technology combines positive qualities of popular methods of regulation of injectivity profiles and polymer flooding. Periodic treatment of injecting wells allows continuously control of water flooding of heterogeneous stratum and secure transitional mode of influence, assisting to enhance oil recovery rate. Accumulated surplus oil production in Russia – more than 3 mln. tons of oil. | |
In 1997 this technology was awarded silver medal and the diploma at 46 International Exhibition of Innovations, Scientific Investigations and New Technologies in Brussels. Average annual oil production at Samotlor oilfield (Russia) due to this method is more than 300 thousand tons. | |
Surfactants displacement is aimed at reducing the surface tension at the oil-water border, increasing oil mobility and improving the displacement of water. Oil Recovery Index of Chemical Methods in Russia is 25–35%. |
