Optimization of hydraulic fracturing treatment in tight sand reservoir of lower indus basin: an integrated approach

Abstract

An approach for post-frac production profiling has been presented in this study by integrating a fracture model with a reservoir simulation model for a well drilled in tight sand reservoir of Lower Indus Basin in Pakistan. The presented integrated approach couples the output from the fracture growth model with a reservoir simulation model to effectively predict the behavior of a fractured reservoir. Optimization of hydraulic fracturing was done efficiently through the work presented in this study. The integrated model was used to perform various sensitivities. The production profiles obtained for each case were subsequently used to determine the most profitable case, using an economic model.

The Effect of Fracture Geometry on Proppant Size in Hydraulic Fracturing Design Optimization

“…The next stage is calculating the hydraulic fracturing plan using a simulator where in this simulator the fracturing geometry design, proppant determination, fracturing fluid selection, and pressure and horse power selection that is suitable for use will be carried out. The use of simulators is common, this aims to be an approach in developing post-fracture production profiles by combining fracture models with reservoir simulation models for wells installed in tight sand reservoirs in the Lower Indus Basin in Pakistan [13]. After the calculations have been carried out using the simulator, the manual calculations and the results obtained from the simulation are then evaluated.…”
