Analysis of Results Confirmation of Simultaneous Inversion for East Siberian Terrigenous Reservoirs

New exploration projects with a scarcity of drilling data give much consideration to advanced high-density 3D seismic studies. Updated high-density seismic data is presumed to be utilized to build detailed geological reservoir models and substantially enhance further exploration drilling. The latest developments in seismic data interpretation stem from inverse transformations of seismic data. Seismic data can be reviewed and interpreted by themselves, without inversion, however, this does not allow us to obtain the most detailed understanding of the structure of the formation, and under certain conditions can lead to an unreliable result. Benefiting from the efficiency and quality of seismic inversion, most oil and gas companies currently employ inversion technologies to enhance seismic data resolution and improve the prediction reliability and reservoir rock properties assessment accuracy, including with regard to porosity and net pay thickness. There are a host of various inversion technologies with some of them to be selected for the quantity and quality of prior geological and geophysical data, as well as for the specific needs to be addressed and the rock properties of of the section under study. The key objective of this publication is to assess the potential of inversion transformations in predicting sweet-spots in terrigenous reservoirs forming part of a challenging seismogeological environment in Eastern Siberia. The simultaneous inversion validity analysis is based on the data obtained from two pilot boreholes of a newly drilled well.
