Method of creation the litho-facial scheme-maps for analysis of Vostochno-Surgutskoe field YUS <sub>1</sub>
In article have been reviewed an operational analysis of Vostochno-Surgutskoe field JUS1 horizon deposits creation process with litho-facial scheme-maps usage. This method allows immediate assess the litho-facial anisotropy of researching object, marking sand bodies and create the basement for detailed litho-facial analysis. The main difference of this method is its simplicity and efficiency, what allows laying the basement for litho-facial analysis at the first stage of 3D geological model creation. <br></br> <b>Materials and methods</b> <br></br> Method of 3D geological models reliability increasing based by litho-facial analysis. <br></br> <b>Results</b> <br></br> Was made litho-facial scheme-map, what truly reflects the researchable region paleogeography, but also allows to change the conceptual model of researchable object operatively. <br></br> <b>Сonclusions</b> <br></br>Methodic submitted in article allows: <br></br>1. To integrate litho-facial analysis into 3Dgeological model. <br></br>2. Make counting of porosity in each litho-facial zone separately. <br></br>3. Decrease risks during the prediction of oil resources extraction.
