Abstract

Summary

This work is aimed at studying the interrelation between the structure of the Earth’s crust and upper mantle and the maturity of source rocks based on modern satellite gravity data. Here, considering recent studies, we propose to use GOCE gravity field models for a gravity field inversion in order to define Moho depth on Volga-Ural oil and gas-bearing province. This will allow us to construct more precise heat flow models and consequently maturity maps of higher accuracy for this region. Volga-Ural oil and gas bearing province is a good region for the goal of this study because it is well surveyed geologically and geophysically. Moreover, it has gotraverse “TATSEIS-2003” where Moho boundary is defined, so the final crustal Model can be calibrated using these data. Besides, there is still a controversy in terms of mechanisms of maturation and migration of oil from Domanic source rocks in such big deposits as Romashkino, so there is a need for further investigation of this region through basin modelling. All the available and needed data as well as a proposed workflow for gravity field inversion are discussed in this study.
