Fine precision between seismic and drilling data is the base for hydrocarbon accumulation properties forecast

Authors: S.V. Lyagushov, G.V. Takkand (KogalymNIPIneft OOO)
Convergence between seismic and drilling data is the basis for predicting the properties of hydrocarbon deposit. It can be argued that rather close connection between them is always there, but it is not always obvious, a lot depends on the accuracy of processing and interpreting the results of well logging and field seismograms processing graph. On the example of reservoirs with complex geological structure, over the field, studied with 3D exploration seismology, it is shown the use of inversions to identify and strengthen these connections, as well as for the geometrization of hydrocarbon deposits. Improvement of the seismogeological deposit model allows to refine the reserves.
