Ryder Scott Reserves Evaluation Techniques
Ryder Scott typically conducts evaluations using one or a combination of techniques as follows: volumetric; well-performance, including decline-curve and rate-transient analysis; mathematical modeling, including the use of material balance and reservoir simulation; and analogy comparing reservoirs with geologic and/or performance similarities.
Team members may include geophysicists, geologists, petrophysicists, petroleum engineers and economists. In some cases, the team uses a complete suite of geological and engineering data. In other cases, all that is needed are well-performance histories. The final step is for the evaluator to cashflow production to generate discounted net present values. Clients regularly ask for different economic runs under various sensitivities to future sales prices or “price decks” and to operating and capital costs.
