Abstract

This project focuses on designing a fracture treatment in a vertical well with the goal of optimizing its parameters to increase its productivity index. The project uses EFRAC 3.3.0.0 software to model and optimize the design of the fracture treatment. The project first compares and selects the optimum fracking fluid, followed by a completion design to choose the best parameters using the optimum fluid selected. The project then analyzes the impact of the number of perforations, perforation diameter, proppant size, injection rate, and duration for each stage on the overall design. The final optimized design includes slick water as the fracking fluid, with a perforation diameter of 0.45 inches, 10 perforations, 20/40 proppant size, 25 BPM injection rate, 15-25-30-minute duration time, and 0-2-4 lbm/gal proppant loading rate. This final design resulted in a productivity index of 6.01, dimensionless.
