## Uncertainty & Sensitivities

Given the methodological approach, including speculative estimation of some input parameters, and lack of real-world
reference data for comparison, the case study results are subject to uncertainty. This case study does not attempt to
quantify uncertainties, but sensitivity analysis may be included in future updates. Users may wish to perform their own
sensitivity analysis using [GEOPHIRES's Monte Carlo simulation module](Monte-Carlo-User-Guide.html) or other data
analysis
tools.

### Stimulation & Construction Inflation Costs

The following heatmaps visualize Electricity breakeven price (LCOE) and NPV sensitivity to stimulation cost and inflation costs during construction (a proxy for construction delays and cost overruns).
Stimulation costs were tested from $2.3M/well (Reservoir Stimulation Capital Cost Adjustment Factor = 0.5) to $9.2M/well (Reservoir Stimulation Capital Cost Adjustment Factor = 2).
Construction inflation costs were tested from $53.58M (Inflation Rate During Construction = 2.3%) to $340.13M (Inflation Rate During Construction = 14.6%).
