Joint analysis of AVO and borehole gravimetry data to improve the resolution in determining the elastic parameters of the medium
https://doi.org/10.18303/2619-1563-2023-1-25
Abstract
The paper analyzes how the use of additional information obtained thought the borehole gravimetric measurements affects the accuracy of determining the parameters of the medium when evaluating elastic impedances in the framework of AVO-analysis. The possibility of increasing the accuracy of seismic survey results in the procedure for determining elastic parameters through the use of borehole gravimetry data has been demonstrated.
