The integrated geophysics of Jurassic carbonate reservoir rock in the outer zone of the Precarpathian foredeep
Keywords:
geophysical survey, carbonate rocks, asymmetry, kurtosis, petrophysical models, broadband acoustic logging.Abstract
The possible allocation of the underlying productive carbonate reservoir rocks according to geophysical
logging was considered. In the article the main interpretation methods of geophysical information obtainedduring
the study of carbonate cross-sections were analyzed. To improve the reliability of the allocation of productive
reservoir rocks in complex geological sections, a new methodological approach to the interpretation of the results
of geological and geophysical studies was developed. It was proposed to use the statistical analysis, such as
asymmetry and kurtosis, in the interpretation of acoustic logging data. The mathematical models of petrophysical
relationships characteristic of carbonate rocks. The approaches used to determine the coefficients of porosity and
oil-gas saturation according to geologic-geophysical studies were reflected, and the results of the broadband
acoustic logging use for the selection and evaluation of performance ratios in geological cross-section, filled with
carbonates, were presented in the article.
