Summary The objective of this article is to evaluate empirical methods of decline curves, in order to forecast the production of a Tight oil source rock reservoir, located in the Middle Magdalena Valley basin, based on petrophysical parameters and fluid properties. The empirical models used in the evaluation are the decline curve models proposed by ARPS, such as: exponential decline, hyperbolic decline and harmonic decline, also other models were used based on the ARPS compilation, proposing more accurate mathematical models such as the Power Law Exponential Decline (PLE) model, Duong Model and the Modifiel Fracture Flow (MFF). A description and comparison of each model is provided, where finally each of the models was evaluated in the shale case study. The methodological development allowed concluding which are the models with the best production fit and that the reservoir located in the Middle Magdalena Valley basin has production potential.
