To know the output potential of hydrocarbons in a reservoir and its optimization, it is necessary to apply different engineering disciplines. One important discipline is petrophysics, which carries out the petrophysical characterization of the reservoir at a static level, and determines the physical properties of the rocks and types of fluids present in the reservoir, mainly porosity, permeability, grain size, and pore and fluid saturation. To determine the petrophysical properties, a geophysical log evaluation is carried out, integrating core data. Five horizons with gas potential were identified at the study area at the Neogene level, which include seven types ofpetrophysical rock types and thirteen flow units. The petrophysical description helped to re-evaluate the reserves and define the rock types and flow units that contribute to production, as well as to identify the areas with output potential in sandy horizons correlated with the study area.

Palabras llave : Log evaluation; petrophysical rock type and flow units.
