A NEW MATHEMATICAL MODEL FOR OPTIMIZING FRACTURE LENGTH IN THE IRANIAN OIL SAND RESERVOIR

abstract 1191605009 issue 119 pp. 147 – 158 31.05.2016 ru 546
Creation of hydraulic fracturing in the physical structure of the reservoir rock is one important way to improve the productivity of oil and gas wells. These artificial channels increase ability of the reservoir rock for conducting hydrocarbons to the wellbore. In this study a new approach has been proposed for optimization of fracture half length in hydraulic fracturing operation. Also, this new method that is a combination of various fracturing geometry models has been proposed for modeling the hydraulic fracturing geometry. We have shown that there is a reasonable agreement between the result of pseudo 3D fracture geometry model and the predicted results from the proposed approach

MODELING OF HYDRAULIC FRACTURING PRESSURE IN RESERVOIR ROCK FOR AN OIL SAND RESERVOIR IN SOUTH WEST OF IRAN

abstract 1181604011 issue 118 pp. 199 – 209 29.04.2016 ru 906
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
