Annotation
The paper considers an approach to the development of deposits of tight oil, characterized by a complex geological structure, ultra-low permeability (less than 1 mD) and saturation differentiation. The use of standard approaches and development technologies for such complex reservoirs makes it difficult to obtain high efficiency of oil recovery. In order to choose the optimal development technology, the applicability of gas methods
for enhanced oil recovery was evaluated using analytical techniques and calculations based on a compositional flow model.
Materials and Methods
The paper gives the numerical estimations of the Minimum Miscibility Pressure (MMP) of oil and various gas agents (APG, CO2, methane) made via correlations and EOS matched to standard studies
of downhole samples. A preliminary feasibility study of various development options for the reservoir in question (water and gas injection) was performed on a sector composite flow simulation model.
Keywords
