Abstract
Aim. The article presents the results of rock physics used to justify the value of performing seismic inversion in predicting reservoir properties in the interwell space in an oil-gas-condensate field in Eastern Siberia.
Materials and methods. As part of the work, an analysis was carried out to find the potential for predicting the reservoir properties of the target formation using 3D and well logging data. An approach has been proposed to justify the implementation of seismic inversion and its type to reduce geological uncertainties when drilling production wells. The process of constructing a rock physics model of the target reservoir is described, and various geological scenarios for modeling elastic parameters are realized.
Results. A rock physics model was built using 7 wells of the field that penetrated the target formation. The analysis of the base scenario and modeling results made it possible to assess the potential of predicting the reservoir, individual lithotypes, saturation in the field of elastic parameters, also with seismic data frequency filter, and to prepare a program for additional exploration of the field to increase the efficiency of drilling production wells.
Conclusion. The results obtained allow us to recommend calculation of simultaneous inversion to reduce geological uncertainties associated with predicting reservoir properties in the interwell space. The conclusions of this work make it possible to translate used approach to other projects in Eastern Siberia with a similar geological structure.
