Why don't you approach it as a simple resource estimation work. That way, your objectives and methodology would be clear:
1. In-place estimation (bare-bones volumetrics)
2. Have a section for discussion on reservoir properties; define the constraints
3. Run elementary decline analyses on existing wells (if any)
4. Model flow thru implementation of new technology (horizontal wells with multi-stage fracs, for example)
5. Run your techno-economics on the forecast results (with sensitivities on flow rates, forecasts, costs, pricing, exchange rate...etc)
