Calculation of vertical pressure by estimating the density graph and integration of seismic data, three-dimensional charts and graphs well

In most oil / gas wells, the P-wave transit time and density graphs are often used to drive reservoir properties such as porosity, permeability and lithology. Moreover, these graphs can be used to calculate and provide the pore pressure model. Economically, indirect methods using seismic data, is most effective, due to the relatively high cost and local information provided by direct measurement of pore pressure in wells. In order to estimate formation pressure from seismic data, estimation of the vertical pressure is required. In this study, to calculate vertical pressure at any depth, a density volume was obtained via studying of seismic attributes. Based on correlation of well log data and estimated density values in well location; density cube estimated based on multi-attribute approach, introduced as suitable result. Then the volume of vertical pressure was calculated using the relationship between the vertical pressure and density, which represents the vertical pressure at any depth.
