This paper presents a new set of Fetkovich type curves for production data analysis. The set extends early-time flow regime to include near-linear up to pure-linear flow, which are lacking in the original set. The proposed set is general but is particularly suitable for tight-gas wells due to the inclusion of the often-observed pure- and near-linear flow behavior. Theory of cross type curves between rate, cumulative production, and time is presented as well as the methodology of cross type-curve matching. Examples are given to show the applicability of the type curves for tight-gas evaluation.
