Prediction of the lithological and physical properties of geological sections of the Predverhoyansky foredeep northern part by means of optimization technology of dynamic interpretation

Abstract
Many geologists think about foredeep promising for exploration of oil and gas. The history of the development of the Predverhoyansky foredeep northern part shows a number of prerequisites allowing to consider this area favorable for the formation of various types of traps. The study area has an abnormally low degree of geological and geophysical study. Based on the new geological and geophysical works which was conducted in 2014-2016 in the Predverhoyansky foredeep northern part, new data on the geological structure of the study area were obtained. The result was the forecast of oil and gas prospective zones. In connection with the relevance of the forecast of filtration-capacitance properties of promising deposits, the technique of ODI (optimization technology of dynamic interpretation) was applied. This technology identifies zones with improved collection properties at a qualitative level, thus, in the future, it will allow to carry out geological exploration more effectively.
Materials and methods
Geological interpretation of seismoacoustic sections obtained using the OTDI technique
Results
The forecast of zones with improved reservoir properties within the priority objects of geological exploration in the Predverhoyansky foredeep northern part is given.
Conclusions
The analysis of data of geological and geophysical works which was conducted in 2014-2016 in the northern part of Predverhoyansky foredeep has been updated geological structure of the study territory. On the basis of the refi geological model of the foredeep northern part, the forecast of oil and gas potential zones and local objects is given. In connection with the relevance of the forecast of fi ation-capacitance properties of promising deposits, to clarify the lithological and physical properties of geological sections of the Predverhoyansky foredeep northern part was applied the technique of OTDI. As a result of integrated application of geological interpretation of seismic sections profi es 2014-2016 and geological interpretation of seismoacoustic sections according to the results of dynamic interpretation with the help of OTDI given a forecast the most promising areas for geological exploration in the Predverhoyansky foredeep northern part. In the future, when predicting the lithological and physical properties of geological sections of the geological exploration and other similar poorly studied areas with a complex characteristic of the fi ation-capacitive properties, it is recommended to use a comprehensive geological interpretation of seismic sections and dynamic interpretation using the method of OTDI.
