Ceuta field is located in the southeastern part of the Maracaibo basin, western Venezuela. The field is a conspicuous high belonging to the Pueblo Viejo trend, a set of strike-slip faults trending northwest. The field has an area of 320 km and is divided into eight fault-bounded blocks where light- or medium-grade oil is being produced. The structural framework is characterized by a major left-slip fault and oil accumulations are associated with compressive and extensive structural features. The deposition of Eocene sediments in some areas may have been controlled by normal faulting and a period of shortening may have altered the character of some of the faults during the late Eocene or later. The main producing intervals are shallow-water marine or fluviodeltaic Miocene and Eocene sands with porosities ranging from 8 to 15% and a production potential of up to 3,500 BOPD from depths averaging 5,182 m (17,000 ft). The reservoirs seem to contain mixtures of hydrocarbons, probably due to the generation of oil in more than one oil kitchen and/or at different migration times from a common drainage area.
