Prestack simultaneous impedance inversion was introduced at the turn of this century with the objective of characterization of target rock intervals in terms of elastic properties, which in turn could be associated with petrophysical properties such as porosity, fluid saturation and volume of shale.
I landed in Bogota in June 1963 for employment with Texpet Colombia. Exploration of the asymmetrical Putumayo sub-Andean Basin had begun in the 1940s when Texpet sent exploration geologists to document any surface outcrops, but the area was still too remote for further exploration. Ten years later, Texpet drilled some two dozen core wells without finding oil. Then, in 1962, exploration picked up and the company moved a houseboat from the Amazon up the Rio Putumayo to a site upstream from the small, remote river town of Puerto Asis.
The concept of digital transformation in the oil and gas industry gets talked about a lot these days, even though the phrase seems to have little specific meaning. So, will there really be some kind of extensive cyber-transformation of the industry over the next decade? “No,” said Tom Smith, president and CEO of Geophysical Insights in Houston. Instead, it will happen “over the next three years,” he predicted.

AAPG and the Brazilian Association of Petroleum Geologists invite you to join us for GTW Brazil 2019: Solutions for Appraisal and Development of Onshore and Offshore Fields, a Geosciences Technology Workshop (GTW) to be held at the Hilton Rio de Janeiro in Copacabana on 13-14 June. The workshop features a series of technical presentations, panels, roundtable discussions and networking opportunities with leaders and experts from Petrobras, Shell, Total, Enauta, and other local and international operators.
One of the persisting challenges in shale reservoir development is the issue of steep decline curves and poor ultimate recovery of hydrocarbons. Dr. Cemal Saydam, a research biochemist in Turkey has developed a revolutionary new green process that dramatically boosts the production of methane. Welcome to an interview with Dr. Cemal Saydam and Yigit Atamer, who explain the product and the process.
AAPG Europe is proud to announce AAPG members will be entitled to attend DEVEX at the SPE member rate. Sign up now and register! DEVEX is now in its 16th year and is the only technical conference of its size which is focused on the full cycle of reservoir discovery, evaluation, development and recovery in the UK and provides excellent opportunities for engineers and geoscientists to come together and share knowledge.
Great breakthroughs have been made in strategic exploration and development of shale oil and gas. To further promote the theoretical research and technological innovation on shale oil and gas exploration and development, AAPG will be holding a GTW in October 2019 in the Dagang Oilfield in Tianjin, China.
The AAPG Foundation is proud to announce the recipient of the 2019 Inspirational Geoscience Educator Award: Brett Carpenter, an assistant professor in the Geology and Geophysics Department at the University of Oklahoma in Norman, Okla.
You’ve heard of it before: the “Big (bad) Crew Change.” Will we have enough qualified people to fill the shoes of the large proportion of career experts getting ready to retire? It was a huge deal in the ‘90s, but what about now? Is it still really an issue, or are we just beating a dead horse?
Engineering of wind farms, development of carbon sequestration projects in shelfal waters, the proliferation of communication cables that connect the world, all of these things suggest that it is time to re-examine what we know about shelf processes both updip-to-downdip and along shoreline, and the influence of shelf processes on erosion and transport of sediments.

Local sea-level changes are not simply a function of global ocean volumes but also the interactions between the solid Earth, the Earth’s gravitational field and the loading and unloading of ice sheets. Contrasting behaviors between Antarctica and Scotland highlight how important the geologic structure beneath the former ice sheets is in determining the interactions between ice sheets and relative sea levels.

Three-dimensional (3D) seismic-reflection surveys provide one of the most important data types for understanding subsurface depositional systems. Quantitative analysis is commonly restricted to geophysical interpretation of elastic properties of rocks in the subsurface. Wide availability of 3D seismic-reflection data and integration provide opportunities for quantitative analysis of subsurface stratigraphic sequences. Here, we integrate traditional seismic-stratigraphic interpretation with quantitative geomorphologic analysis and numerical modeling to explore new insights into submarine-channel evolution.

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.

The carbonate sequences that were deposited in the now exhumed Tethyan Ocean influence many aspects of our lives today, either by supplying the energy that warms our homes and the fuel that powers our cars or providing the stunning landscapes for both winter and summer vacations. They also represent some of the most intensely studied rock formations in the world and have provided geoscientists with a fascinating insight into the turbulent nature of 250 Million years of Earth’s history. By combining studies from the full range of geoscience disciplines this presentation will trace the development of these carbonate sequences from their initial formation on the margins of large ancient continental masses to their present day locations in and around the Greater Mediterranean and Near East region. The first order control on growth patterns and carbonate platform development by the regional plate-tectonic setting, underlying basin architecture and fluctuations in sea level will be illustrated. The organisms that contribute to sequence development will be revealed to be treasure troves of forensic information. Finally, these rock sequences will be shown to contain all the ingredients necessary to form and retain hydrocarbons and the manner in which major post-depositional tectonic events led to the formation of some of the largest hydrocarbon accumulations in the world will be demonstrated.

The Betic hinterland, in the westernmost Mediterranean, constitutes a unique example of a stack of metamorphic units. Using a three-dimensional model for the crustal structure of the Betics-Rif area this talk will address the role of crustal flow simultaneously to upper-crustal low-angle faulting in the origin and evolution of the topography.

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.

Paleozoic North America has experienced multiple mountain building events, from Ordovician to Permian, on all margins of the continent. These have had a profound effect on the resulting complex basins and their associated petroleum systems. Subsequent uplift, erosion and overprinting of these ancient systems impedes the direct observation of their tectonic history. However, the basin sedimentary records are more complete, and provide additional insights into the timing and style of the mountain building events. In this study, we employ ~90 1D basin models, ~30 inverse flexural models, isopachs, and paleogeographic maps to better understand the Paleozoic history of North America.
Physics is an essential component of geophysics but there is much that physics cannot know or address.

While there are many habitats that are associated with the deposition of organic-rich marine and lacustrine source rocks, one important pathway is linked to the onset of increased basin subsidence associated with major tectonic events. A key aspect is that this subsidence is spatially variable, with the uplift of basin flanks contemporaneous with the foundering of the basin center, resulting in a steeper basin profile.
