Abstract:
Method for extracting hydrocarbons, including very heavy ones, using gas generating chemical reactions, wherein a compound for generating hot gases and initiators or, as the case may be, stabilizers for a chemical reaction are separately fed into the respective source bed in a controlled manner, where least four coplanar horizontal openings are created in each plane intersecting the location, where the compound and the initiators get together, and, simultaneously or after a specified delay, gas-forming substances are fed, said substances being contained in a mixture along with the compound or supplied separately, wherein the reaction takes place underneath a packer, whereby prerequisites for an artificial gas lift are created, whereupon the reaction is maintained by adding the compound, whereby such values of temperature and pressure are obtained which cause the solid rock to cleave.

Claim (Index 4):
The according to  claim 1 , wherein reagents, possibly contained in a mixture together with sand or with a proppant, are fed into one or more stimulation boreholes and the hydrocarbons are extracted from the adjacent boreholes, the accompanying formation of gases occurring, provided that an adequate geometrical arrangement exists, in an amount that is sufficient for causing a strong gas lift to occur, thus enabling the hydrocarbons to spontaneously flow from the adjacent boreholes, a possibility of using standard pumping methods for the exploitation from the adjacent boreholes being thereby not excluded.
