Abstract
  This paper aims to optimally determine petrophysical facies according to well log data. Using the automatic classification method of K-NN (K-Nearest Neighbours), petrophysical facies can be determined even though not optimally. For optimal determination of facies, the K-NN method is combined with FastICA ...  Read More

Abstract
  Reservoir geophysics studies have playeda significant role in exploration and production activities during the last decades. These techniques often try to identify the lithology and fluid content of the reservoir by utilization of pre-stack seismic data. The most effective type of these studies is performed ...  Read More
