A METHOD FOR THE RECOVERY AND EXPLORATION OF HYDROCARBONS FROM A SUBTERRANEOUS RESERVOIR BY MEANS OF GASES, A SYSTEM AND AN APPARATUS FOR THE EXECUTION OF THE METHOD

摘要

A method for the secondary and/or enhanced recovery and exploration of hydrocarbons, especially crude oil, shale gas etc. from a subterraneous reservoir by means of gases produced by exothermic chemical reactions implemented in such a way that the above mentioned gases are produced from supplied chemical reagents, optionally further compounds, optionally air or oxygen and/or water in a chemical reactor, whereas the gases generated this way are introduced into to the productive formation (pay zone) in a controlled way, without the use of any additional supportive technical equipment, and by the effect of the elevated temperature and pressure in the productive formation (pay zone) the viscosity of the crude oil in the formation decreases, the pressure in the formation increases and potentially desired fractures in the formation occur, leading to the enabling of heavy crude oil recovery, to an enhanced heavy-, medium and light crude oil recovery or to the enabling of or enhancement of natural gas production. The invention further provides for a system for the recovery and exploration of hydrocarbons by applying the above mentioned method and for the apparatus design that is suggested in this system for the recovery and exploration of hydrocarbons in accordance with the above mentioned method.
