The primary goal of the PETROMEXBAS Project is to provide petroleum companies with the modern data that will be used to prioritize their exploration programs and hence investment opportunities in Mexico.

The Project will include:

џ full (bulk and molecular) source rocks and oil seep geochemical characterization

џ new analytical results on reservoirs and seals, such as

– U-Pb detrital zircon geochronology,

– Apatite & Zircon fission track data,

– Clay mineralogy and other isotopic methods

This newly obtained geological and geochemical data will be further integrated with existing geological and geochemical data to clarify the complex geological and petroleum history of the eastern Mexican basins, specifically:

Location of PETROMEXBAS Modules

The eastern Mexican sedimentary basins contain significant discovered/developed and undiscovered hydrocarbon

resources. Yet, these basins are relatively poorly studied, and the modern geological, geophysical and geochemical data

are scarce. Tectonic history of the basins and the adjacent Sierra Madre Fold Belt remains largely unconstrained. There

are significant uncertainties about depositional history of sedimentary basins, hydrocarbon source rock evolution, and

petroleum potential as a whole.

The proposed PETROMEXBAS Project is designed to acquire new data on oil seeps, source, reservoir, and seal rocks by

conducting field works in each basin in eastern Mexico. These new data, once acquired and integrated with existing G&G

data, will allow us to refine the geological history and the petroleum systems of the eastern Mexican sedimentary basins,

so that we can constrain both onshore and offshore hydrocarbon potential with much greater accuracy.

Project Goal & Design

Project Rationale

џ tectonic phases and structural styles

џ siliciclastic rock provenance and depositional environments

џ magnitude and timing of uplift and erosion

џ thermal history of the basins and hydrocarbon charge

џ regional deposition environments and sedimentary facies.

The project is consists of 5 modules:

џ Module 1: Regional Geological Overview

џ Module 2: Southeastern basins

џ Module 3: Veracruz Basin

џ Module 4: Tampico-Misantla Basin

џ Module 5: Burgos Basin

The Module 1 is designed to provide a comprehensive revision and compilation of published and unpublished public-domain data on geology, paleogeography and hydrocarbon systems of the eastern Mexican sedimentary basins. Over past two decades, there has been a significant amount of data published in PhD theses and limited-access reports that are largely unavailable to a broad petroleum geoscience community. We designated a considerable effort to collect these data and to compile them in a series of ArcGIS databases that allowed us to revise regional tectonics, stratigraphy, paleogeography and petroleum systems of the vast region of the eastern Mexico and the entire Gulf of Mexico.

Module 1: Regional Geological Overview

The Report will include ArcGIS databases containing all produced maps and used spatial data

The Module 2 addresses the geology and hydrocarbon systems of the Southeastern Mexican basins. The key element of this Module, as well as the Modules 3, 4, & 5 will be the extensive filed work and sampling of rock exposures, including Mesozoic rocks in the deformed Sierra Madre foreland region and Cenozoic rocks exposed within the basin itself. We will acquire a representative collection of source, reservoir and seal rocks that will be high-graded for a series of analytical studies such as RockEval, organic matter geochemistry, U, Th, and He isotopic composition, U-Pb detrital zircon geochronology, Apatite and Zircon fission track studies, and some other.
