CARLOS, Guamialamá,; JOSE, Freire,  e  RAUL, Valencia,. Impact of the Applied Methods for the Determination of Permeability and its Influence in the Management of the Reservoir in Shushufindi Field. Rev Politéc. (Quito) [online]. 2020, vol.45, n.2, pp.41-50. ISSN 2477-8990.  https://doi.org/10.33333/rp.vol45n2.04.

Permeability is one of the main properties in reservoir characterization, as well as for the estimation of the productivity of a well. There are several methods for its measurement or calculation during different stages of development of a field. All these methods differ in some aspects such as the type of permeability that they determine whether absolute or effective, volume of observation, technology used, theoretical foundations and inconveniences encountered during the acquisition and estimation of this property.

In this work, permeability distributions were determined, and the methods were compared with core-well logs, well logs-wireline formation testers and pressure transient analysis - rate transient analysis. From these comparisons, it was possible to identify the differences in the permeability values as well as the differences in the measurement scales.

Once the permeability values were established from each method, an analysis and interpretation were made to determine a theoretical productivity of each of them, then they were compared with real production data in order to establish the best method for estimating this property for Shushufindi field.
