Integration of Production Analysis and Rate/Time Analysis by Use of Parametric Correlations—Theoretical Considerations and Practical Applications

摘要

Well-performance analysis in unconventional reservoirs is a challenging task because of the nonuniqueness associated with estimating well and formation properties. Also, estimating of reserves can be uncertain because of the very long transient-flow periods. Recent semiempirical rate/time relations have been shown to model the rate/time behavior properly for wells in unconventional reservoirs. This study focused on finding theoretical and empirical relationships of rate/ time-model parameters with well and formation properties.
