This Month’s Talk: 

The US Shale Oil/Gas Revolution: An Historic Opportunity to Advance American Society* 

Paul H Nadeau, University of Stavanger, Inst. Petroleum Technology

ABSTRACT: Potomac Geophysical Society, Crown Plaza, Tyson’s Corner, VA, 16th February, 2017

Recent technical advances in unconventional or “tight” shale oil and gas extraction1 are reviewed in light of the dramatic rise in US oil and gas production volumes over the last 5 years.

This unprecedented increase in energy production and reserves additions has catapulted the USD into the world leadership position. Using petrophysical analysis and other data, estimates of recoverable US oil reserves are now on the order of 1 Trillion barrels, equal to one-half of the original global conventional oil endowment, or the total volume of oil produced on our planet over the last 100 years.

The strategic significance and geopolitical implications of this remarkable achievement cannot be overstated2. The geological foundations of these energy reserves rest on the development of an extensive Palaeozoic foreland basin along the SE Margin of North America during the formation of the Pangea super-continent, followed by an even greater Mesozoic foreland basin along the western convergent margin from Alaska to Mexico during Pagean break-up and associated creation of the Atlantic Ocean3. No other continent is so favoured with respect to the accumulation of multiple organic-rich shale intervals, source rock deposits, and related mature petroleum systems.

Now the effective and efficient management of these strategic energy reserves must reside with the responsible governmental organizations, which alone can establish policies and regulations to ensure that these vital national resources are not squandered, or adversely impact domestic as well as global environments4.

The learnings from Norway, a small nation of 5 million people, and their ability to create the world’s largest sovereign wealth fund of c. 1 Trillion dollars over the last 20 years5 on a volume only 5% of current estimated US reserve base, is advocated for the repayment of the 20 Trillion dollar US national debt over the coming decades.

The repayment period could then be followed by the creation of a US wealth fund to advance health, education, infrastructure, scientific research, and environmental stewardship on historic global scales.

UMD Geology: Pratt on Coastal Plain strata in earthquakes

2017 Geology Colloquium Series

Friday, February 3rd 2017 at 3:00 pm
in PLS 1140

The influence of eastern U.S. Atlantic Coastal Plain strata on earthquake ground motions, and damage in Washington, DC, during the 2011 Mineral, Virginia, Earthquake

During the 2011 Mw5.8 Mineral, VA earthquake, many buildings in Washington, DC, including national landmarks like the Washington National Cathedral, the Smithsonian “Castle,” and the Washington Monument, sustained damage despite being 130 km from the epicenter. The surprisingly large amount of damage from weak ground motions raises questions of how much the southeast-thickening sedimentary strata of the Atlantic Coastal Plain (ACP) strata beneath the city amplify and trap seismic energy. Partially consolidated ACP marine sedimentary strata overlie crystalline or indurated sedimentary rocks throughout coastal regions of the eastern U.S., extending more than 200 km inland from the coast. The strata taper landward from as much as 1 km near the coast to pinching out in the Washington, DC area. Shallow sedimentary strata are known to amplify earthquake ground motions due to low seismic impedance and strong reverberations. Between November 2! 014 and August 2015, we used 27 seismometers to measure ground motions across Washington, DC, using four sites on crystalline rocks as reference sites. We also used data from continental-scale seismic experiments that span the ACP to examine the influence of the broader ACP strata on earthquake ground motions. Recordings of teleseisms and regional earthquakes provided data with sufficiently high signal-to-noise for computing amplitude ratios relative to the bedrock sites. Amplifications of 10 or greater are found in the Washington, DC area due to the ACP strata, with the peak amplifications occurring near the estimated resonant frequencies of buildings throughout the city. Amplitudes decrease as the strata thicken, but even coastal sites on 600 m of ACP strata show amplification factors as great as 5. We use the frequency of the resonance peaks to invert for an average velocity function within the ACP strata. This work indicates that amplification of short-period ground mot! ions by thin ACP strata contributed to the damage in Washington, DC, d uring the 2011 earthquake, and documents longer-period amplifications that could affect larger structures beneath coastal regions of the eastern U.S. during earthquakes.

Dan Sarewitz

The scientific enterprise is a precious jewel in humanity’s narrative. It’s been the most reliable basis for uncovering provisional truths about how the world works, for technological innovation, and for decision-making on scales ranging from the personal to the global. But as Dan Sarewitz, co-director of the Consortium for


Thomas Will

Science, Policy & Outcomes at Arizona State University, sees it, the common and long-held claim that the self-direction of science accounts for its social benefits is a myth and has led to alarming flaws in science’s organization, funding, and reward systems. The most important foundation of the scientific enterprise — trust in its fundamental validity and social value — is now at risk, he says. Join Sarewitz and Will Thomas, an historian of science and a policy analyst at the American Institute of Physics, for an historically-anchored discussion about what ails science and what the remedies might be, the social benefits we should expect from our massive investment in science, and what’s at stake if we ignore inconvenient truths about the present state of scientific inquiry.

Holtz on “Paranormal Geology” at NSF HQ

“Hollow Earth, Sunken Continents, and a World Made of Plankton? A Look at Paranormal Geology” at 1:30 p.m. on January 14 at the National Science Foundation, Room 110, 4201 Wilson Boulevard in Arlington. (Use the Ballston-MU Metro stop; enter NSF from the corner of 9th St. N. and N. Stuart St.)

A description of his talk: “The public is familiar with pseudoscientific interpretations of biology (Creationism, cryptozoology, etc.) and astronomy (astrology, UFO abductions, etc.), but all sciences have their pseudo-versions. There have been various pseudo-geologies proposed over the centuries: interpretations of the structure and composition of the Earth radically at odds with our current understanding. Among these are ideas that the Earth is hollow (various configurations, including a notable one where we are on the inside of curve!), sunken continents (Atlantis, Lemuria, and beyond), and a truly bizarre idea that all physical matter on Earth was once alive. Some of these ideas were proposed in a scientific context, but have survived in various circles long after their refutation. Dr. Holtz will examine the origins, beliefs, and fates of these alternate Earth interpretations.”

Sponsored by National Capital Area Skeptics, the event is free and open to the public. For further information, visit:

January 2017 meeting of the Paleontological Society of Washington

The Paleontological Society of Washington

7:00 pm, Wednesday, January 18

National Museum of Natural History, Constitution Ave. entrance

The Miocene Planet of the Apes

Ashley Hammond

Postdoctoral Scientist, Center for Advanced Study of Human Paleobiology (CASHP),

Department of Anthropology, George Washington University

There were probably more than 30 genera of apes alive throughout Africa and Eurasia during the Miocene (23-5 Mya), whereas there are just a handful alive in forests in Africa and SE Asia today. Here I will discuss the major locomotor transformations that occurred during ape evolution, as revealed by the anatomy of the pelvis and femur of fossil apes. We see that the majority of apes in the past moved differently from the apes that persist today, and that there was an increase in adaptations for suspensory locomotion relatively late during ape evolution.

Non-Smithsonian visitors will be escorted from the Constitution Ave. entrance of the NMNH to the Q?rius auditorium at 6:50 and 6:55 p.m. Society members will host the speaker for dinner at the Elephant & Castle (1201 Pennsylvania Ave.) prior to the meeting. Members may meet at the restaurant or inside the Constitution Ave. entrance of the NMNH at 5:00 and walk to the restaurant as a group.
