The use of cluster analysis for the segmentation of the physicochemical properties of shale gas deposits

Cluster analysis methods have been adapted for the segmentation of data describing the generative and reservoir properties of shale gas-type formations. Tests were carried out for the segmentation of data describing the geochemical properties of core samples collected from eight wells within the stratigraphic unit of Llandovery (Silurian). The study was conducted in two stages. During the first stage, data segmentation was performed for three wells described by the largest number of measurements. The second stage of data segmentation involved a set of samples originating from all wells.
