Geochemistry

Most of the stratigraphic sequence is mature to overmature (Figure 6). Type II kerogen predominates in the basin. However, the samples could be affected by thermal maturity (Figure 7 ). Average organic matter content from most samples is below 2%; however some samples of La Luna and Aguas Blancas formations ranges between 2 and 4%. Most of the samples show poor to good generation potential with values below 10 mg HC / g rock.

Based on the generation quality parameters HI and S2, La Luna and Aguas Blancas formations show the best source rock characteristics.
