Hydraulic Fracturing Design Optimization - Bakken Case Study
The case study is prepared to illustrate the capabilities of the optiFracMS multistage fracturing optimization software.
The goal of the study is to optimize a fracturing design for a Bakken formation.
Two fracture design cases were considered:
- Operating company fracture design based on a Big Data application
- optiFracMS optimized fracturing design
For the both cases a production forecast was calculated and cumulative oil production was compared.
Inputs
Rock and reservoir data:
Interval | Depth (ft) | Zone Thickness (ft) | In Situ Stress (psi) | Poisson's Ratio | Young's Modulus (10^6 psi) | Fracture Toughness (psi/in^0.5) |
