Abstract:
The petroleum-generating potential of five samples from Hole 515B, Vema Channel, and of 23 samples from Hole 516F, Rio Grande Rise, was analyzed. Organic carbon and pyrolysis data indicated that source rocks of good quality are not present. Microscopic examination showed predominance of woody organic matter, which is more favorable for the generation of gas in a mature stage; all samples, however, are still thermally immature.
