Abstract

Basin and petroleum systems modeling in the poorly studied oil and gas provinces like the Okhotsk Sea region leads to significant uncertainties in the simulation results, which is reflected in the risk assessment. It requires using modern methods that allow working with a minimum input dataset while capturing all key geological processes. The potential of one of these methods automated thermotectonostratigraphic approach or inverse modeling is demonstrated through a basin thermal history reconstruction case study on the example of CDP 1632. Being based on rare published data, two different scenarios that are based on rare limited published data are considered for the tectonic evolution of the basin. These scenarios demonstrate different thermal histories and organic matter evolution, despite the successful calibration using a limited dataset on temperature and vitrinite reflectance. The additional use of gravimetric data allows us to improve the model. It is the first application of this approach in the region of the Far East, so uncertainty in modeling results, as well as the pros and cons of the approach, are discussed.
