Abstract:

The Candeias field, in the south-central part of the Reconcavo basin, Brazil, was discovered by Conselho Nacional do Petroleo (CNP) in 1941 as a result of surface geology and seismic interpretations. The reservoir rock consists of fractured lenticular sandstone (1st, 2nd, and 3rd "pay" zones) and fractured shales (4th zone). The sandstone zones form typical stratigraphic traps, because they are isolated sandstone bodies within a thick formation which is essentially shale. The structural geometry appears to be irrelevant.
