... in the industry for production forecasting, but the application is usually based on empirical observations and intuitive assumptions. This paper provides the basis for dividing production history of these wells into at least four segments. We first examined rigorous solutions to governing flow equations...

For example, in Canada, retrograde condensate reservoirs produce gas and condensate, but the volume is often reported as total gas-equivalent hydrocarbon volume. Our goal in this study is to deconvolve production histories of aggregated gas-equivalent hydrocarbon...

..., is strongly affected by the presence of wells with noisy production history. Forecasting individual wells on the other hand is time consuming, and inaccurate for wells with limited production history. In this work, we propose model-based type wells for forecasting production for individual wells, using...

Paper Number: URTEC-2019-471-MS
... conservative course of action would be to assume an immediate transition at the end of production history to an exponential (bBDF = 0) BDF regime, but this would forecast unreasonably low future production in most cases. Instead, it is more reasonable to assume the transient period continues to a specified...

... number of tight oil wells with more than five years’ worth of production history. Less than 20% in the Permian tight oil wells have been producing more than 60 months. As the Wolfcamp play matures, the later-life performance of wells starts to matter more. Even with record rig counts, the number of new...
