The 2015 annual meeting of the Geological Society of America
(GSA) in Baltimore (November 1-4) saw the debut of
the GSA Energy Geology Division (EGD), a continuation but topical expansion of
the Society’s second oldest division, the Coal Geology Division.
The Coal Geology Division was founded in 1954. But, as energy resources have evolved, so have energy research interests and career
opportunities. The portion of coal as part of the energy budget in many regions
is declining, and other options, including nuclear and other non-fossil fuel
sources, provide increasing portions of our power needs. The number of earth
science departments that include coal geology has also dwindled in the last 20
years so there are increasingly fewer coal geologists trained at the university level.
The discussion on amending the focus of the division, both
within the division and between the division and the Society, has gone on for almost
two decades. One option was to just add petroleum science formally to the
mission: those educated or trained in coal petrographic techniques, for
example, frequently work on petroleum source rocks. The final name change,
approved in March 2015 by 80% of members voting, reflects the inclusion of geologists
and geology topics related to all aspects of renewable and non-renewable energy
exploration, extraction, and use. The
official purpose of the expanded division “is to provide a suitable forum for
presentation of scientific papers and discussion of problems of mutual interest
in the geologic study of energy resources, to stimulate research and
interchange of scientific information about energy resources and related issues
within the wide range of their geologic significance, and to act as an
organized group in promoting these objectives within the framework of the
Geological Society of America.” (https://community.geosociety.org/energydivision/aboutus/about

At the 2015 GSA meeting, the re-named Energy Geology Division was
primary sponsor of two Geologic Energy Research topical oral sessions (https://gsa.confex.com/gsa/2015AM/webprogram/Session37614.html)
(https://gsa.confex.com/gsa/2015AM/webprogram/Session38992.html)
and one poster session (https://gsa.confex.com/gsa/2015AM/webprogram/Session38751.html). These sessions provide a sampling of topics under the expanded subject theme of the Division: inorganic chemistry of coal, fly ash and gas shale;
uranium deposits; CO2 storage reservoirs; geothermal systems; oil sands;
oil/gas produced waters, hydrocarbon geochemistry; thermal maturity and organic
petrology; basin tectonics, heat flow, and petroleum systems analysis; nuclear
power plant siting; and borehole geophysics.
The Division was also the lead sponsor of “From Peat to Coke: Honoring the Legacy of William Spackman”.
Dr. Spackman (1919-2014) had a comprehensive knowledge of and research career in coal from deposition to
utilization including paleobotany, palynology, peat-forming environments, coal
petrography, and industrial coal usage. He began the internationally-recognized
coal geology research program at Penn State that produced probably the majority
of US coal scientists from the 1950’s through the 1980’s and continues today as
the Coal Science and Technology section of Penn State’s Earth and Minerals
Sciences Energy Institute. Several of the presenters were Spackman students or students of his students
(I am one of the latter but did not give a talk).
Other 2015 sessions where EGD was a co-sponsor include “Shale gas basins: Their
stratigraphy, sedimentary environments, tectonics, and structural evolution” (oral and poster sessions); and “Water and Fluid Migration During Energy Development: Implications for Hydraulic Fracturing, CO2 Storage, Enhanced Oil Recovery, In Situ Uranium Recovery, and Waste Water Injection”.
The Division also sponsored a field trip, “Geologic investigation of the impact of a subsurface coal fire: Centralia, Pennsylvania”.
The Spackman theme session preceded the annual Division
business meeting and awards ceremony and reception. The Coal Geology Division
had two major awards:
the Gilbert H. Cady Award for “outstanding contributions to the field of coal
geology”, and the Antoinette Lierman Medlin coal science student research
scholarships (two) for completion of field work and completion of
lab/analytical work. Dr. Claus F. K. Diessel of the University of Newcastle,
Australia, best known for his research in the sedimentology and sequence
stratigraphy of coal-bearing successions, was this year’s (2015) Cady award recipient.
The Cady award and Medlin grants will continue as Energy Geology Division awards
in coal geology. However, the Division hopes to add new categories that will
mirror the Cady and Medlin awards but span energy topics in earth science. (2019 update: The Energy Geology Division proudly announced the new Curtis-Hedberg Petroleum Career Achievement Award named after two prominent petroleum geologists, who were past Presidents of GSA including GSA's first woman president.)
