FWG1 EXPONENTIAL DECLINE DEVELOPMENT MODEL

A mathematical expression for such development indexes as recovery rates and rocovery percent of reserves is established on the basis of the FWG1 exponential decline development model. As a result the FWG1 exponential decline development model is proposed and the effect of parameter on the model is analyzed. It is shown that when c 1/n t equals 1, the V D=e -1 is a static point. For the convenience of policy decision in the initial stage of development, the method of determing the FWG1 exponential decline development model is proposed. Accordingly, the log V D log R p, log V D log( c 1/n t ), log R p log( c 1/n t ) type curves are created. The proposition of assessment method and the matching methods for three point parabolic method and the three type curves for the FWG1 exponential decline development model in the mid late stage development lays a foundation for the mid late stage prediction.
