PROGRAM OVERVIEW
The Campeche Reimaging program merges over 100,000 sq km of narrow-azimuth data and ocean bottom seismic data
from the CNH, to provide the high quality images necessary for prospecting in the complex salt of the Campeche basin.
Using the latest ION imaging technologies, including deghosting, SRME, RTM and tomography, we are providing a timely,
cost-effective solution for evaluating this highly prospective area during Mexico’s bid rounds.
KEY COMPONENTS

CAMPECHE GEOLOGICAL OVERVIEW
Campeche North
The Campeche North Reprocessing program combines 51,000 km sq of five legacy seismic surveys, Sayab, Ixic,
Temoa, Yoka, and HanSur, acquired separately, in the southern Gulf of Mexico Salinas del Istimo Basin. Here, Jurassic
age source rocks, Cretaceous carbonates, massive salt structures, and tertiary sediment fairways exist throughout this
geologically complex basin where proven petroleum systems exist throughout the Mesozoic and Tertiary stratigraphic
units. The updated seismic and velocity model better images the structural and stratigraphic traps at subsalt level
and highlights abyssal plain amplitude anomalies within the local and regional fold systems. The reprocessing of the
legacy CNH data integrates the latest processing and imaging techniques across the regional scale contiguous 3D
volume while the consistency and scale of the dataset allows the user a seamless perspective from which to explore
the petroleum rich basin.
COMMERCIAL
Mexico is the most prolific region offshore in America, and one of the world’s largest untapped resources of oil and gas.
Recent significant discoveries in the Perdido and Sureste Basins are key indicators that the petroleum potential is
definitive and with substantial rewards. In addition to its geological potential, recent changes to regulation and fiscal
terms have been designed to bring international interest to Mexico. The result has seen a revitalization of the Energy
industry which puts Mexico EUR potential in a similar category to such established provinces as Norway, UK and
Brazil but with the promise of yet undiscovered potential with new investment.
Arbitrary line shows folded and trusted structures from compressional forces on the Recent to Upper Jurassic section above the autochthonous salt and from salt diapirism. The flat lying base of salt is very well imaged.

Campeche South
The Campeche South Reprocessing program encompasses 24,000 km sq four legacy seismic surveys, Anegada, Holok,
Cequi, and Bolol, acquired separately, in the southern Gulf of Mexico Salinas del Istimo Basin. This southward
continuation of the Campeche North program continues the trends of its northern counterpart such as substantial salt
structures and compressional fold and thrust formations. Unique to the area however is the change in structural
regime to counter-regional extensional formations in the Comalcalco Basin and the oceanic crust expression in the
basinward abyssal plain. Observations of significant thickness and character changes in the Mesozoic section lead to
a new understanding of the geologic timing, basin dynamics, and source rock potential in the area. Additionally,
utilizing well control for velocity analysis and consistent model building across survey boundaries provides an updated
image which ties directly into the recent successful Zama discovery.
Campeche south Image summary: Diapiric and thrusted salt along with thrusted and folded Upper Jurassic to Miocene compressional structures above autochthonous salt.
Campeche north Summary: Diapiric salt bodies rising from the autochthonous salt to the surface, folding above the autochthonous salt, Lower Jurassic and SDR’s below salt.

Campeche Shallows Image Summary: Listric faulting from the surface to the base of salt expanding the Eocene to Recent section and Upper Cretaceous producing structures on the Campeche Shelf.
Campeche Super Shallow
The Campeche Super Shallow Reprocessing program combines another 9 legacy seismic surveys totaling over 9,500
km sq plus 1,700 km of 2D using a contiguous velocity model which expands southward from the previously re-imaged
Campeche programs. These shallow water surveys near the Pescadores and Coatzacoalcos mini-basins are
characterized by the landward continuation of the Sal Somera canopy and the Catemaco fold belt. Complexities in
lithological identification between thin, rugose, salt canopies, extensional detachments, and the chaotic mass
transport sequences result in challenges to the merging and re-imaging of the vintage data; however, regional
consistency paired with local well control and extensive experience in the area allows for the reprocessed dataset to
tie, confirm, and further develop exploration leads within the area.

Campeche Shallow Waters
The Campeche Shallow Waters Reprocessing program combines 15 legacy seismic surveys, acquired separately in the
southern Gulf of Mexico offshore area of Comalcalco, Pilar de Akal, and Macuspana. The south-eastward extension of
the Campeche North and South programs, the 15,000 km sq Shallows dataset reveals the extensional features of the
Comalcalco and Macuspana basins and the associated thick sediment fairways as well as gaps in the Mesozoic
carbonate packages presumably rafted away by thick salt evacuation. Moreover, The Pilar de Akal, which sits between
the two extensional basins, is home of the world renowned Cantarell field. By seamlessly merging all surveys together
and combining with the North and South programs, this dataset offers unprecedented perspective for exploration
teams to tie known, historic areas of success, to others prospective plays and targets in the region in 3-demensions.
