Authors : Nouri Fatma Zohra . Djekrif Soumaya .
Abstract
In shale gas reservoir development, determination of hydraulic frac- ture geometry for horizontal wells is still a demanding challenging task. One of the approaches for hydraulic fracture optimization is based on reservoir simulation, and to improve efficiency and ac- curacy, an automatic and robust procedure integrating the gradient descent method with gas reservoir simulation has been developed by many authors, where some proposed an automatic and robust optimization procedure based on the gradient descent method, that aims to enhance both the efficiency and accuracy. However we have to make sure which gradient descent method to use for optimizing hydraulic shale gas reservoirs fractures, as this requires several fac- tors and variations to be taken into account. The wise choice is to consider the nature of the problem (convex or non-convex), the size of the dataset, and the specific requirements of the reservoir simula- tion. Advanced variants and multiple initial points can enhance the effectiveness of the optimization process. This method can achieve significant computational reduction and high prediction accuracy for various shale gas reservoir cases. Here we analyse numerically this method for different cases and present some numerical results
