The Vizcaino fore-arc basin accumulated approximately 4 km (∼13,000 ft) of upper Albian–middle Eocene siliciclastic marine sedimentary rocks derived from the Peninsular Ranges in Baja California. Data from eight exploratory wells document the micropaleontological content and lithological characteristics of these rocks.

The Isthmian salt basin in the southern Gulf of Mexico can be divided into the Yucatán and Campeche subbasins, separated by a base-salt high near the nose of the Yucatán platform.

The AAPG Student Poster Competition began in 1996, when a single first-place award was given to Ian Robert Gordon of UT Austin for his poster. Since then, the program has expanded, soon including international schools, leading to 2019, when four awards were given, some to international students. Jack Kenning, a second-year doctoral student in the Earth and Atmospheric Sciences Department at UH, won with a poster entitled “Controls of Cenozoic Mass Transport Deposits on Hydrocarbon Prospectivity of the Mexican Ridges Fold-Belt, Western Gulf of Mexico.”

Call it an exploration recovery. Call it a rebound. But it feels like the oil and gas industry is returning to health in fits and starts. That could be because the patient was sicker than we realize. Any measure of how far exploration has come back should take into consideration how far back it started.

Trends in exploration are moving away from new ventures and refocusing on proven basins – most likely inspired by the success of the Permian Basin. The Permian Basin is now known as a “super basin,” and has become a beacon of hope for Latin America and South America, which are now known to have substantial super basin potential as well.

After years of a brutal industry downturn, Latin American oil and gas is finally starting to get back its strength. But just barely, according to Aditya Ravi, senior analyst for consulting firm Rystad Energy in Oslo. Challenges for the Latin American oil industry include a financial hangover from the oil price collapse, political uncertainties and a struggle to replace declining production. In Latin America, “Brazil and Guyana are the hotspots when it comes to exploration offshore. Until something big comes up in Argentina, it’s unlikely” those provinces will be overshadowed soon, Ravi said.

Explorer Geophysical Corner


The Gulf of Mexico is one of the most prolific oil and gas basins in the world. Understandably, the region is also home to many deeply buried mature source rocks and migration pathways to the surface, which result in petroleum seepage on the seafloor. The emerging mineral-rich fluids invite microbes, mollusks and clam to feed on them, and these communities located around the seep locations form hard surfaces and appear to be different from the surrounding seafloor. Such hard surfaces are acoustically reflective and thus are detected by the technology available today.

Explorer Historical Highlight


The Chixchulub crater on Mexico’s Yucatan Peninsula was long believed to be the result of volcanic activity, until one young geologist with a No. 2 pencil, some drafting triangles and a calculator made an earth-shattering discovery.

Explorer President’s Column


I received my 40-year certificate from AAPG. At the bottom it reads, “In Recognition and Appreciation of your Loyalty to AAPG,” but it is I who should be thanking AAPG for allowing me to be part of this great organization. AAPG allowed me to network and make contacts with smarter people than me and to learn and expand my knowledge base. This is a great profession, and I have found a career in the geological sciences to be extremely rewarding.

Abstracts from more than 50 papers addressing the geology of the area from the southern onshore of North America to the northern onshore of South America, including the Gulf of Mexico, Bahamas Platform, Yucatán, Caribbean (Colombia, Venezuela), Grenada and Tobago basins and adjacent Atlantic. Integration will improve understanding and promote investigation of lesser-explored/debated areas, such as the Caribbean. Recent seismic and drilling discoveries from other offshore frontiers will help assessment of their hydrocarbon potential.
