MULTIVARIATE TOMOGRAPHY METHOD OF SEISMIC SURVEY DATA Russian patent published in 2020 - IPC G01V1/28 G01V1/30 G06F17/50 

FIELD: data processing.

SUBSTANCE: invention relates to a computer-implemented method for multivariable tomography of seismic survey data. Method involves obtaining a plurality of realizations of solutions of an inverse kinematic seismic survey problem. Method includes stages, at which time of arrival of seismic waves in parametric form is measured from seismograms obtained as a result of seismic experiment data processing. Multiple realizations of measured values of arrival of reflected waves are obtained as a result of averaging of data of initial seismograms with random weights uniformly distributed on a segment with observance of normalization condition. Multiple realizations of responses of inverse kinematic problem for each depth horizon are obtained from multiple realizations of measured values of arrival of reflected waves, multiple implementations for previous horizons, as well as multiple smoothed with random solutions weights. Based on the obtained plurality of realizations of the responses of the inverse kinematic problem, probability cubes and estimates of the reliability of deep constructions are constructed.

EFFECT: high reliability of deep structures.
