Abstract
In this abstract, we present a methodology of prospective objects identification in Khadum formation based on joint study of rock physics modelling, new techniques of quantitative seismic interpretation, lineament analysis and fault-block zones allocation. Techniques for building detailed volumetric lithological model of the studied deposits based on the integrated study of geological and geophysical data are proposed. A detailed analysis of the input information allows to consider a rock type with high porosity as a prospective object, which can be identified using the “Vp/Vs ratio - acoustic impedance” cross-plot. This create the precondition for predicting prospective objects in the inter-well space using the results of seismic amplitude inversion. The map of perspective objects in Khadum formation in the study area was formed based on conducted research and the obtained results
