Mapping of seismic and lithological facies is a very complex process, especially in regions with low seismic resolution caused by extensive salt layers, even when only an exploratory view of the distribution of the reservoir facies is required. The aim of this study was to apply multi-attribute analysis using an unsupervised classification algorithm to map the carbonate facies of an exploratory presalt area located in the Outer high region of the Santos Basin.

During these times of global economic uncertainty, political turmoil and climate change discussions, some, both inside and outside the energy industry, question the value of investing in oil and gas exploration. At the same time, new discoveries, technological advances and collaborative partnerships make exploration more exciting than ever. ExxonMobil Exploration Company President Stephen Greenlee addressed these parallel perspectives during “The Future of Oil and Gas Exploration,” the annual Michel T. Halbouty Lecture he delivered at the AAPG Annual Convention and Exhibition in San Antonio in May.

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.

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.

During the 1950s, Walter Karl Link was considered one of the world's best oil exploration geologists, often compared to Wallace Pratt, John E. Brantley, Everette Lee DeGolyer, Lewis MacNaughton and A. I. Levorsen. His renown aroused the interest of a newly created oil company in Brazil, called Petrobras.
