Geological Prediction Technology

摘要

A method of processing geological data is provided for input to a geostatistical modelling algorithm to predict a value for a parameter relating to a physical property of the Earth. An input data set corresponding to a measured geological parameter is processed to determine a characteristic function of the input data with respect to a geological measure. The input data is transformed to reduce spatial bias with respect to the geological distance measure by applying an inverse function. A statistical weighting is calculated for the transformation and the transformation and weighting are used to predict a representative value of the physical property corresponding to the measured geological parameter. A data processing apparatus and computer program product are also provided.

1. A method of processing geological data, comprising the steps of:
receiving an input data set representing a measured geological parameter of a volume of the Earth, the input data set having a set of values for the geological parameter, the values potentially having spatial bias whereby there is a variation in a value of the geological parameter depending upon spatial coordinates within the Earth volume; analysing the input data of the geological parameter with respect to at least one given geological measure to define a characteristic function of the input data with respect to the at least one given geological measure; applying an inverse of the characteristic function to the input data to perform a transformation to reduce the spatial bias of the input data set with respect to the given geological measure to generate transformed input data set; calculating a statistical weighting of the transformation depending upon an estimated accuracy of the determined characteristic function; and predicting a representative function for the geological parameter with respect to the at least one given geological measure based upon the transformed input data set and the statistical weighting, wherein the geological parameter is a physical property of the Earth's interior.
