What is Production Decline Analysis Techniques about?
1) Three decline curve models (single phase oil with d=0, black oil with d=0.33, and solution gas drive with d=0.67) provided essentially equivalent fits to production data from an oil well over 4 years. The black oil model best predicted future production over 11 additional years. 2) Both an exponential (d=0) and hyperbolic (d=0.5) decline curve fit production data from a gas well over 2 years with R^2 > 0.8. The hyperbolic model better matched subsequent production data, supporting the recommended d=0.5
