Lateral Distribution Estimation of Geological Risks Related to Structural Uncertainty

In this work a method of lateral distribution estimation of structural uncertainty is proposed, which considers factors of uncertainty related to determination errors of seismic data initial parameters. The estimation is delivered in a deterministic way during the analysis of internal convergence of seismic data. Determination errors of kinematic parameters are estimated: time and velocity. External convergence of seismic data with well data is taken into account. As the result, a map of standard deviation of structural surface is calculated which then is used to construct a probability (risk) map of a structural closure.
