There is an abundance of basic lithologic and fluid data from this stratigraphic unit as a potential target for CO2 injection. The trapping mechanism for Repetto fields is dominantly structural, with many fields occurring on anticlines and in overturned strata along fault zones (Yeats and Beall, 1991). Secondary hydrocarbon accumulations occur in stratigraphic traps where deep-sea fan deposits pinch out in mudstones (Redin, 1991) Main site http://www.beg.utexas.edu/environqlty/co2seq/co2data.htm
