  With a sample of kerogen   from Maracaibo Basin (La Luna
  Formation in its Maraca brook section), the method to   characterize kerogen by
  diffuse reflectance – Fourier transformed - infrared spectroscopy   has been
  optimized. Trough obtaining spectra for 1, 3, 5, 10 and 20%   mixtures of kerogen
  in KBr matrix and varying certain processing parameters, it is   recognized that
  the optimum ratio is the 5% mixture with a total of 40 scans per   analysis. The
  behavior of signal intensity, the base line characteristics and   the influence
  of humid-absorbed water were evaluated. The study aims to test   the advantages
  of the technique and then to shape the analysis as an important   complement to
  geochemical information for the understanding of petroleum   systems,
  specifically petroleum generation which is an especially   interesting area in
  Venezuela. In this way, the technique could be used for   establishing and
  applying compositional parameters of kerogen samples and other   similar organic

    Key words:   diffuse, infrared, kerogen, optimization, reflectance.
