Summary:Title screen
The purpose of this study is to examine the seismic response of fluvial deposits by using the method of forward seismic modelling. The studied outcrop is located in Kemerovo Region, 250 km from Tomsk and is about 500 m in length and about 30 m height. The exposure deposits belong to the fluvial depositional environment and the age of sediments is Lower Cretaceous. In this work the synthetic model construction was provided with the help of simple convolution-based method. Modeling was performed in two software products Petrel and Madagascar. To construct the impedance cube, petrophysical properties were taken from the analogue field, which formed in similar depositional environment. The sensitivity analysis of detailed seismic pictures on the frequency change was carried out. Thus, 8 models were built in a frequency range of 25 to 200 Hz in steps of 25 Hz. Attribute analysis was provided to estimate the ability of Net to Gross ratio of fluvial reservoir forecasting by using seismic attributes. Furthermore, an analysis of the effect of fluid saturation on seismic image of fluvial deposits was conducted.
