Abstract
The paper describes in-seam hydraulic fracturing with packing of intervals in uncased holes using solidifiable polymer materials. The idea of this approach includes the usage of two pipe columns nested in one another. The external column is employed for hole cleaning and for delivery of hydrofracturing facilities in the selected interval of the hole. The internal column is composed of five separate hydraulic channels, allowing the polymer bridge components and breakdown fluid to be injected independently. Using the mathematical modeling the authors analyze stress distribution on hole walls in the vicinity of isolated interval depending on elastic properties of polymer bridges.
