System of processing and presenting drill hole data

Abstract

The invention relates to a system of processing and presenting drill hole data such as obtained by taking a drill hole measurement, characterized in that the drill hole measurement data are divided into successive depth bands having a predetermined depth window; for each depth band a spectral analysis is carried out producing for each such depth band a spectral band; the spectral band of each separate depth band is compared with climate-related deposition cycles, such as the known Milankovitch cycle data, that relate to the examined area; and the predetermined depth window of the depths bands is adjusted to realize an optimal correlation between the spectral band of at least one depth band and the respective cycle or cycles.

1 . A system of processing and presenting drill hole data such as obtained by taking a drill hole measurement, characterized in that 
 the drill hole measurement data are divided into successive depth bands having a predetermined depth window;    for each depth band a spectral analysis is carried out producing for each such depth band a spectral band;    the spectral band of each separate depth band is compared with climate-related deposition cycles, such as the known Milankovitch cycle data, that relate to the examined area; and    the predetermined depth window of the depths bands is adjusted to realize an optimal correlation between the spectral band of at least one depth band and the respective cycle or cycles.    
     
     
         2 . A system according to  claim 1 , characterized in that 
 the cycle pattern of the spectral band is determined from a first depth band;    the cycle pattern of the first spectral band is used as prediction for the spectral band of a second depth band succeeding the first depth band;    the occurrence of a discontinuity in a predicted spectral band is determined in relation to the actual measurement data; and    said discontinuity is an indication for a geologically significant boundary layer.    
     
     
         3 . A system according to  claim 1  or  2 , characterized in that the discontinuities, which are determined with respect to the successive depth bands, are integrated with the variable parameter being the depth to which the drill hole measurement data refer.
