... years (and several annual evaluations) to reach boundary-dominated flow, often making Arps based production forecasts for these wells unreliable. Application of methods based on production history, such as rate-transient analysis (RTA), may provide reasonable production forecasts but require wellhead...

.... In most of the cases, the hybrid YM-SEPD and Arps models led to more accurate oil production forecasts than other alternatives. Our analyses of solution gas forecasts indicated that solution gas production forecasting is possible but there is still need for more research in this area. production...

... in flow regime identification and production forecasting. In some LRS's, BDF is observed within 12 months. In any case, it is essential to identify or to estimate the time to reach BDF and to discontinue use of transient flow models after BDF appears or is expected. We validated our methodology using...
