Net Present Value (NPV) and Internal Rate of Return (IRR) are fundamental financial metrics used to evaluate the economic viability of a project. By assessing these indicators, companies can make informed decisions regarding investments in reservoir development and management. Accurate NPV & IRR assessment ensures that resources are allocated efficiently to maximize returns.

3. Optimal Stage Spacing

Determining the optimal stage spacing in hydraulic fracturing operations is critical for enhancing well performance. Proper spacing between fracturing stages can significantly influence the stimulation of the reservoir and the overall recovery of hydrocarbons. Geology-specific frac design plays a vital role in optimizing these stages to achieve the best results.
