Patent ID: 8065086

Claim:
A method for selecting samples of geological data for estimating missing data in well logging comprising: a. acquiring a data set comprising multiple data values indicative of at least one geological characteristic at locations in a subsurface interval of rock; b. identifying locations i in a subsurface rock where values v i are to be predicted; c. identifying data values associated with each location i such that each data value associated with a location i is an element p i and all elements p i form set P; d. identifying locations j in a subsurface interval of rock where data values v j from the data set, are known; e. defining elements q j , to be samples v j and data at the same location as samples v j at a multiplicity of locations j to form set Q; f. for an element p i in set P, identifying one or more elements q j in set Q with data values indicative of the same geological characteristic as the p i sample is indicative of, such that the identified elements q i constitutes data elements r i ; and g. defining a data set R, comprising data elements r i .
