Sedimentary model of terrigenous reservoir layers В13 and В10 of Chonsky group of fields

Authors: E.M. Turovskaya, Y.G. Eremin (Gasprom neft NTC LLC, RF, Saint-Petersburg)

Key words: sedimentary modeling, litotips, facies, reservoir properties, secondary changes.

The article presents a view on the process of terrigenous sediments deposition within Chonskaya group of fields. The construction of the model was carried out with the involvement of all available geological and geophysical information. Integrated use of data obtained in the process of wells drilling and 3D seismic alloweded with greater confidence distinguish facial zones and forecast their development through areas with a low well density index.
