Fracture geometry depends on stresses and rock properties in hydraulic fracturing operation. Poisson’s ratio imports directly in the calculations related to formation stresses. The most important reason for limiting fracture height is the natural stresses contrast resulting from the differences with Poisson ratios. Without this difference, fracture would have largely uncontrolled height. The goal of this study is mathematical investigation of the effect of Poisson’s ratio on the formation stresses that is necessary to select value of breakdown pressure in hydraulic fracturing operation. In this article, a mathematical model has been coded using “MATLAB” software for prediction of stresses in the various layers. This designed program is able to present both digital and graphical output results for different values of Poisson’s ratio. At the end, stresses exerted on the different layers of the several real oil reservoirs have simulated and breakdown pressures have determined
