Explorer Article

In June of 2020, I set out to hike just the first 470 miles of the Appalachian Trail. Less than two weeks into my adventure, I thought to myself, “What the heck, why not do the whole thing?” It was then that I decided to hike the entirety of the nearly 2,200 miles that summer. I later decided that I would also write a book about it. “Rocks, Roots and Rattlesnakes” is that story of my daily adventures, as written from a geologist’s perspective.

Some aspects of seismic interpretation, such as picking horizons and well-imaged faults, can be easily explained to a new interpreter. Other aspects, such as recognizing carbonate buildups, karst collapse, mass transport processes or volcanic intrusions, require not only an understanding of the underlying geologic processes, but also an understanding of their 3-D seismic data response. Although an experienced interpreter might be adept in using seismic data to map each of these features, they might also be challenged in explaining to the novice interpreter in a quantitative manner how they constructed their map or geobody.

Explorer Historical Highlights

There are two main oil and gas producing sedimentary areas in France: the Paris Basin and the Aquitaine Basin. The presence of oil seeps and bitumen deposits has been known since ancient times in the western part of the Aquitaine basin, a 35,000-square-kilometer triangular polygon bordered to the north by the city of Bordeaux, to the east by Toulouse and to the south by the Pyrenees Mountain chain separating France from Spain. These hydrocarbon shows were observed close to surface anticlinal structures such as the Sainte-Suzanne dome, southwest of Pau or in the caprocks of salt diapirs at Salies de Bearn and Dax to the north.

Welcome to an interview with Natalia Amezcua, who is Research Deputy Manager in the Research and Development Direction of the Mexican Geological Survey. She also serves on the technical committee for AAPG’s Hedberg Research Conference on the Geology and Hydrocarbon Potential of the Circum Gulf of Mexico Pre-Salt Section, 4 – 6 of February in Mexico City. In addition to discussing the Gulf of Mexico, the conference will also include discussions of analogues and other depositional and structural models for pre-salt reservoirs in other parts of the world.

Fault interpretation is an important step in seismic structural interpretation and has a bearing on the quantitative interpretation that may eventually be carried out. This requires the meaningful recognition of the faults within the proper geological context of the area. In Oklahoma, we see wrench faulting with strike-slip faults and other associated features.

Presented by Kevin C. Hill, Associate Professor, University of Melbourne Gravity modelling of Australia's southern margin reveals that the initial rift with Antarctica was beneath the current Ceduna Delta. A regional, high-quality seismic traverse from the coast to oceanic crust across the Bight Basin has been assembled and interpreted in detail, then balanced, restored, decompacted, and replaced at paleo-water depths. The Late Cretaceous Ceduna Delta developed above a Late Jurassic-Early Cretaceous rift basin in three stages punctuated by significant pulses of uplift and erosion across areas >100 km wide and with up to 1 km of erosion. The Cenomanian White Pointer delta prograded into deepening water and hence underwent gravitational collapse. This was terminated in the Santonian when the Antarctic margin was pulled out from below, thus supplying heat to a remnant thicker outer margin crust, causing doming and erosion. Importantly, this established the saucer-shaped geometry of the Ceduna Delta that persisted throughout its development, so that any hydrocarbons generated in the southern half of the basin would have migrated towards this outer margin high. The Tiger Formation was deposited in shallow water in a full rift basin prior to breakup, which was followed by regional thermal subsidence. The Hammerhead delta developed on the newly formed passive margin but was terminated by another pulse of uplift and erosion, perhaps associated with a change in plate motion at the end of the Cretaceous. The finite element modelling of this proposed tectonic evolution will test its validity and predict hydrocarbon generation and migration through time.

DL Abstract

For well over a century there have been conflicting indications of the strength of the crust and of faults and what controls them.  Much of our ignorance comes quite naturally from the general inaccessibility of the crust to measurement--in contrast with our understanding of the atmosphere, which is much more accessible to observation as well as more rapidly changing.  Crustal strength is best understood in deforming sedimentary basins where the petroleum industry has made great contributions, particularly in deforming petroleum basins because of the practical need to predict. In this talk we take a broad look at key issues in crustal strength and deformation and what we can learn from boreholes, earthquakes, active fault systems, and toy models.

DL Abstract

Subsurface risk and uncertainty are recognized as very important considerations in petroleum geoscience. And even when volume estimates are relatively accurate, the reservoir characteristics that determine well placement and performance can remain highly uncertain. In analyzing results and work practices, three aspects of uncertainty are reviewed here.
