Uncertainty estimation of structural model for production wells planning
Abstract
The article shows the need to complement the well rating assessment of the seismic structural models uncertainty. The paper presents an example of uncertainty estimation of structural models in the process of planning new wells. Implemented of the seismic model error estimation using modifications of the cross-validation method. Discussed the limitations and solutions of cross-validation in the "complete cross-validation" modification. The implemented approach has been tested on the planned wells in the Novogodnee and Vyngapurovskoe oil fields.
