New Insights into the Stratigraphic Framework and Depositional History of the Paleocene and Eocene Chicontepec Formation, Onshore Eastern Mexico

Course Content

A detailed biostratigraphic analysis and stratigraphic framework of the Paleocene and Eocene Chicontepec Formation in the Tampico-Misantla basin, onshore eastern Mexico, was conducted using 33 wells. The objective was to have an independent re-evaluation of the geological framework for future evaluation of the resources.The Eocene and upper Paleocene stratigraphy in the basin is very complicated and it was found that a well spacing of 5-10 km was necessary in order to identify the depositional character of each sequence. A detailed Wheeler diagram, with time increments of 0.1 Ma, was constructed for the stratigraphic framework using the interpreted graphical biostratigraphic data on the wells. Rock accumulation rates (uncorrected for compaction, dewatering etc) in the sequences are between 10 and 20 cm/1000 yrs. The regional stratigraphic framework is defined by five sequence boundaries: SB 65.5, SB 60.4, SB 54, SB 46 and SB 38.1. Once these sequence boundaries were established it was possible to reconstruct the depositional history of the Eocene submarine fans which were sourced from the southwest margin of the basin. After SB 54, there are five sediment entry points into the basin from the southwest. The northern two entry points coincide exactly with two canyons identified from Chicontepec outcrop studies (Cossey and Van Nieuwenhuise, 2011). Additional entry points are identified to the south of the outcrop study area where fieldwork was inconclusive, but the subsurface evidence indicates the presence of three more canyons. After SB 46, there are six sediment entry points into the basin from the southwest. The additional entry point correlates exactly with the large San Lorenzo canyon which was identified from fieldwork (Cossey and Van Nieuwenhuise, 2011).

Since its founding in 1917, the American Association of Petroleum Geologists has been a pillar of the worldwide scientific community. The original purpose of AAPG, to foster scientific research, to advance the science of geology, to promote technology, and to inspire high professional conduct, still guides the Association today.

AAPG provides publications, conferences, and educational opportunities to geoscientists and disseminates the most current geological information available to the general public.

As the world's premier professional association for explorationists, AAPG is about the science of petroleum geology.

It's also about the people.

AAPG's membership is made up of more than 40,000 members in 129 countries in the upstream energy industry who collaborate – and compete – to provide the means for humankind to thrive.

AAPG provides the network of communications that allow those professionals to succeed.

We invite you to see who we are, what we are about and to contact us for membership information or details about the many services we provide.
