EMD Set for San Antonio Meeting

The Energy Minerals Division (EMD) will be sponsoring an unprecedented number of sessions, forums and short courses at the upcoming 2008 AAPG Annual Convention, which will be held April 20-23 in San Antonio.

With EMD sponsorship of 16 oral and poster sessions, three forums, four short courses/workshops and one field trip, the 2008 convention promises attendees an unusual opportunity to discover more about unconventional hydrocarbons, energy minerals, geothermal energy and geospatial information – the primary focus areas of EMD.

The convention theme will be “Deliver the Conventional: Pursue the Unconventional,” which in itself reflects the growing interest in unconventional energy resources. 

The 16 oral and poster sessions will be included under four themes, as noted below in the list of EMD convention activities.

EMD Short Courses
  • Coalbed Methane and Shale Gas Exploration Strategies: Workshop for Sorbed Gas Reservoir Systems (instructors – A.R. Scott, W.A. Ambrose, M. Grigg, M.A. Ilhan, R. Olson, T.J. Pratt, M. Mavor, S.C. Ruppel, A. Marsh and D. Westacott).
  • Fundamentals of Gas Hydrate Resource Evaluation (instructors – A. Johnson and T. Collett).
  • Principles of Geologic Carbon Sequestration (instructors – H.E. Leetaru, J. Kaldi, M. Holtz, J. Pashin, T. Meckel, I. Krapac, S. Greenberg, D. Curtiss and M.L. Coueslan).
  • Fundamentals of ArcGIS for the Petroleum Industry (instructor – J. Harrison).
EMD Field Trip
  • Basin-Margin Bitumen Deposits in the Uvalde Area of Southwest Texas(leader – T. E. Ewing).
EMD Luncheon

The EMD Luncheon will be held on Wednesday, April 23, and will feature Robert Finkelman, an expert in the emerging field of medical geology, with a talk titled “Will Coal Burn Brightly in the Future?”

With the public focus on the environmental and health effects of coal – especially coal-generated power plants – this talk promises to be both timely and startling in its conclusions.

He also will touch on other relevant topics, including an update on the future of coal based on a National Research Council (NRC) report due out this fall, which examines the coal industry from “cradle to grave” (mining to energy transmission) to answer the question of whether our country will be prepared to meet the demands of energy from coal in the year 2030.


Special thanks are due to Mike Wiley, EMD technical program chair, and to Amy Sullivan, EMD short course and field trip chair, for their diligence in organizing the extensive list of convention offerings. We hope that the stimulating program will encourage AAPG members to “get unconventional” by learning more about the focus of EMD and joining its growing membership.

Note also that the 2008 AAPG convention will be held during the city’s week-long party – Fiesta – so there will be many activities for participants and spouses throughout the week.

We hope to see you in San Antonio.

Judges Needed for San Antonio

With such a formidable number of EMD-sponsored sessions set for San Antonio, there clearly is a critical need for securing qualified judges to help assess our technical program.

Creties Jenkins, who is serving as EMD judging chair, would no doubt be grateful for early volunteers.

This study documents that Danian-aged sand remobilization of deep-water slope-channel complexes and intrusion of fluidized sand into hydraulically fractured slope mudstones of the Great Valley sequence, California, generated 400-m (1312 ft)–thick reservoir units: unit 1, parent unit channel complexes for shallower sandstone intrusions; unit 2, a moderate net-to-gross interval (0.19 sand) of sills with staggered, stepped, and multilayer geometries with well-developed lateral sandstone-body connectivity; unit 3, a low net-to-gross interval (0.08 sand) of exclusively high-angle dikes with good vertical connectivity; and unit 4, an interval of extrusive sandstone. Unit 2 was formed during a phase of fluidization that emplaced on an average 0.19 km3 (0.046 mi3) of sand per cubic kilometer of host sediment. Probe permeametry data reveal a positive relationship between sill thickness and permeability. Reservoir quality is reduced by the presence of fragments of host strata, such as the incorporation of large rafts of mudstone, which are formed by in-situ hydraulic fracturing during sand injection. Mudstone clasts and clay- and silt-size particles generated by intrusion-induced abrasion of the host strata reduce sandstone permeability in multilayer sills (70 md) when compared to that in staggered and stepped sills (586 and 1225 md, respectively). Post-injection cementation greatly reduces permeability in high-angle dikes (81 md). This architecturally based reservoir zonation and trends in reservoir characteristics in dikes and sills form a basis for quantitative reservoir modeling and can be used to support conceptual interpretations that infer injectite architecture in situations where sands in low net-to-gross intervals are anticipated to have well-developed lateral and vertical connectivity.

Seismic correlations and well data confirm that deep-water carbonate beds of Mesozoic age have been found above the shallow allochthonous salt canopy in the northern Gulf of Mexico. These rafts of carbonate strata often overlie equivalent age Mesozoic carbonates in their correct stratigraphic position below the salt canopy.

The origin of keel structures is presently not well understood. As deformation occurs after shallow canopy emplacement, the keels are fairly recent developments geologically. Volumetrically few but intriguing observations suggest possible basement involvement in keel formation.
