THE LA LUNA/RÍO NEGRO(.) PETROLEUM SYSTEM AT THE URDANETA WEST FIELD, LAKE MARACAIBO BASIN, NW VENEZUELA: 1D BASIN MODELLING AND SECONDARY OIL MIGRATION
This paper investigates the timing of hydrocarbon generation in the northern part of the Urdaneta West field in the NW of the Lake Maracaibo Basin, NW Venezuela, based on 1D basin modelling at three wells referred to as wells X, Y and Z. Kitchen areas were identified and secondary migration directions were inferred based on analyses of the thermal and burial history of the Upper Cretaceous La Luna Formation source rock and the geochemistry of 20 oil samples from the Río Negro Formation reservoir. Aliphatic hydrocarbons in the oil samples were analysed by gas chromatography – mass spectrometry (GC‐MS) while the vanadium‐nickel and sulphur contents were determined by energy dispersive X‐ray spectrometry and inductively coupled plasma optical emission spectroscopy, respectively. Bulk and molecular characterizations indicated that the oils originated from a marine carbonate source rock containing oil‐prone Type II kerogen, consistent with generation by the La Luna Formation.
期刊介绍：
Journal of Petroleum Geology is a quarterly journal devoted to the geology of oil and natural gas. Editorial preference is given to original papers on oilfield regions of the world outside North America and on topics of general application in petroleum exploration and development operations, including geochemical and geophysical studies, basin modelling and reservoir evaluation.
