Lithological logging
WebWhat is a borehole record? Boreholes range from one to several thousand metres deep. Borehole records are produced from a geologist’s or surveyor’s observations of the rock core extracted from the ground and typically include locality and lithological descriptions with depth and thickness. Webtransformation. The results of lithological interpretation of well logging data were classified into two classes - reservoir and non-reservoir. Reservoir was encoded as 1, while non-reservoir was encoded as 0. The classification results of well logging data were approximated onto the grid using the dominant frequency of class occurrence in
