Abstract
Currently for challenging oil deposits, in particular for the deposits with high-viscous oil the well-known traditional methods of development are ineffective. Therefore, the search for new technologies to develop and operate such fields
for the purpose to increase oil recovery significantly and to stimulate its production is of fundamental importance. One of these methods with BH zone thermal treatment is the use of heat generated by thermo-chemical reactions
based upon the application of nitrogen-generating compounds (NGC) such as ammonium nitrate (NH4NO3) and sodium nitrite (NaNO2). The composition based upon these compounds is applied in the procedure of thermal gas chemical effect (TGCE). Hydrodynamic modeling was used to perform the preliminary efficiency assessment of this thermal gas chemical procedure for high-viscous oil fields in Samara Region.
Materials and methods
Reproduction of well operation history matching process in hydrodynamic model including the injection of thermo-chemical composition into formation bottom-hole zone, followed by thermo-chemical reaction, forecast on process efficiency of thermo-chemical effect.
