Dilatance technology is the most effective technology in the sphere of intensifying of the underground fluid extraction and significantly surpasses the existing technologies in terms of effectiveness and durability.
- Productivity increase:
oil wells – 1,8-3,5 times;
gas wells – 2-7 times; - Average duration of the effect.
The average duration of the effect of conservation is 2,5 years, significantly longer compared the technology of hydraulic fracturing and other intensification technologies. - The Dilatance technology is probably the only available technology capable of increasing the coefficient of extraction of underground fluids from oil and gas deposits by 3-10%. It is especially useful for exhausted and “freezed” deposits and wells.
- The Dilatance technology is the most safe intensification method from ecological point of view, due to its low environmental impact and absence of any polluting agents. Moreover, the use of dilatance technology allows achieving the estimated production capacity with a reduced number of operational wells, resulting in lower environmental impact on the exploited deposits.
- Uniquely short term of on-site activities of 1-2 days, after that the well can be operated in normal production mode.
PERSPECTIVES OF THE TECHNOLOGY
The dilatance technology is currently the most perspective technology of extraction of hydrocarbons from shale formations. With the existing methods of extraction the required well productivity is ensured by the repeated use of the hydraulic fracturing. The dilatance technology also allows such successive treatment, resulting in the increase of the effective radius of the horizontal borehole. At the same time, the cost of such operations is defined not by the product of multiplication of the cost of a single treatment on the number of operations, but appears significantly lower. It is explained by the fact that a significant part of the cost of dilatance treatment is formed by the operations of determining the dynamic parameters of the producing formation and calculations of the parameters of dilatance treatment. The aforesaid operations are taken into account only once in case of treatment of wells located within the same producing formation, regardless of the number of required successive operations of dilatance treatment.
