Optimizing Fracture Stimulation Design in Unconventional Reservoirs

To enhance the speed and effectiveness of developing unconventional assets, the oil and gas industry now has a robust design and execution workflow supported by advanced mathematics and algorithms based on an entirely new approach. This paper reviews the requirements and describes new fracture and reservoir simulators tied to net pressure, i.e., bottom hole pressure compared to least principal formation stress. The fracturing treatment design applications enable better-informed engineering decisions in both the design and execution phases to help ensure the desired fracturing treatment is being effectively placed. The process includes workflows based on the model predictions in order to increase fracture complexity, determine spacing, and maximize the connected fracture area. The new developments can lead to improved production and decreased cost per BOE for operators developing unconventional assets like shale.
