Stochastic Decline Curve Calculator – Gas Wells (Demo)




This Excel-based software will perform estimates of reserves and associated values for oil wells using the stochastic method. Input parameters include initial rate, b factor, decline rate, final decline rate, product prices, expenses, capital costs, and discount rate. Distributions for input parameters can be normal, log normal, or uniform. Results for gas, condensates and NGL reserves, revenue, expenses, income, and NPV are created in a standard table that can be customized by the user. Additional output includes the P90, P50, P10, and mean type curves.
