Abstract

Summary

An important aspect for exploration work is the presence of critical parameters of the productive deposits. To solve this problem, a table was compiled with this information for unconventional reservoirs of North America. When analyzing the logging data, it was shown that as the clay content decreases (less than 75%) and the porosity increases (more than 9%), the probability of the appearance of productive intervals in the Paleogene sediments of the Central and Eastern Ciscaucasia increases. Geomechanical properties make it possible to differentiate between brittle and ductile deposits. The intervals with maximum fractures and permeability are characterized by Young’s modulus of more than 20 GPa and Poisson’s ratio of less than 0.3. The importance of considering flexural faults in the interpretation of seismic data is shown. The integration of various geometric attributes and seismic inversion makes it possible to identify sweet spots for place a horizontal wells and performing hydraulic fracturing.
