.... This analytical method estimates average reservoir pressure as a function of cumulative water injection. Fillup is found by extrapolating the linear trend of reservoir pressure versus cumulative water injected. The advantage of this technique is fillup volume is estimated with flowing data that is captured...

... profiles and the history matched models are blind tested on a part of well history to validate the model. The proposed technique used can extrapolate the average reservoir pressure in the future to allow forecasting GOR trends with reasonable accuracy and an extremely low computational cost owing...

..., and scalable method to analyze every well in the field to support the pace of operations and data-driven decision-making. The method combines the concepts of diffusive time of flight and material balance to estimate the dynamic drainage volume under transient flow and calculate the average reservoir pressure...

... by the interplay between the competing opposite effects of drawdown, compressibility and relative permeability. Transient IPRs are not based on average reservoir pressure, but on specified times. In fact, we propose a triple combo IPR consisting of a set of 3 flow durations (e.g. 30-, 90- and 180-days, or 1-, 3...

.... For the radial flow problem, this can be taken even further to show that the average pseudo-pressure and, therefore, average reservoir pressure is a constant within the drainage radius for which the log-approximation is valid. These expressions represent significant advancements in the realm of pressure...

..., temperature, gas properties, and average reservoir pressure. The proposed model is valid for Knudsen numbers less than 1 and it stands up under the complete operating conditions of a reservoir. Our model accurately predicts results as reported by other empirical models. Finally, the model shows that pore...
