The Cantarell complex, 80 km northwest of Ciudad del Carmen in the Campeche Sound of the Gulf of Mexico, consists of a broad NW-SE trending, faulted anticline. The oil field, categorized as a super giant, has five blocks bounded by faults (Figure 1).

The stratigraphic column for this area of the Gulf of Mexico (GOM) indicates stacking of shelfal Cretaceous and Upper Jurassic carbonates and clastics, overlying an extended salt layer of Jurassic age.

Based on reserves, the complex is the eighth largest oil field in the world. Cumulative production exceeds 10 billion barrels of oil. Current production exceeds 2 million b/d.

This article describes the results of a 2003 reinterpretation of the 3D OBC seismic cube acquired in 1997.


   Discussion
 
There has been much debate regarding the structural style of this area. An earlier attempt to explain the coexistence of compression and extensional features postulated a strike-slip transpressional model. In accordance with that hypothesis, faults should be very high angle, therefore involving the oceanic basement. We question this view because it doesn't fit the plate tectonic kinematics . . .
