Histogram

A histogram is a graphical method that shows data frequency distribution. It is especially useful when there are a huge number of observations, which means a major quality tool with a vast range of applications. Histograms can be applied to a property distribution in a reservoir grid, mainly because it contains an enormous number of cells. As a manner to construct a histogram, the data must be split into intervals, as illustrated in the graph. In such case, the histogram evinces the oil saturation distribution along the reservoir grid. It is noticeable that most of the cells are in the highest values interval, which suggests a reservoir with good hydrocarbons’ potential.
