The easier-to-produce hydrocarbons are currently being or have been extracted. Inorder to extract harder-to-produce hydrocarbons, we need to better define the Caballos formationcharacteristics.We obtained an acceptable match between the rock-physics laboratory measurements and the petrophysicalproperties estimated through the use of seismic data.We used well logs to guide the seismic measurements in the estimation of both porosity and gamma-rayresponse (from seismic attributes), and acoustic impedance (via seismic inversion), using a neural networkapproach.We applied a probabilistic neural network (PNN) because of its particular characteristics of 1) mapping nonlinear relationships between seismic and well log data; 2) incrementing both accuracy and resolution whenperforming inversion, as compared to conventional inversion, and; 3) using a mathematical interpolationscheme not implemented as a black box.Poisson and Vp/Vs ratio provide a means to discriminate between high and low reservoir-rock quality at theCaballos formation. Finally, we analyzed three angle gather stacks (0°-10°, 11°-20° and 21°-30°) throughelastic inversion. 2005 artículo científico 0122-5383 https://www.redalyc.org/articulo.oa?id=46530103 en http://www.redalyc.org/revista.oa?id=465 CT&F Ciencia, Tecnología y Futuro application/pdf ECOPETROL S.A.
