‘The new business of energy’

Special ‘EMD Day’ Set in Cape Town

AAPG’s Energy Minerals Division (EMD) will sponsor a plethora of activities at this year’s International Conference and Exhibition, Oct. 26-29 in Cape Town.

The main highlight for our Division is what we’re calling EMD Day, co-sponsored with the Geological Society of South Africa, which will offer several items of particular interest to not just EMD members but others who are engaged in energy mineral activities.

This EMD emphasis will be held Wednesday, Oct. 29, featuring two oral and four poster sessions that cover topics of “The New Business of Energy.”

Our goal in putting all of the EMD sessions on one day is to draw South African coal and uranium geologists to the convention who could not otherwise consider investing three days for the talks.

Offered on EMD Day will be:

  • Four presentations on coal.
  • Five oral talks on oil shales.
  • Four posters on tight or basin-centered gas plays.
  • Seven posters on gas hydrates.
  • Six posters on CO2 sequestration.
  • Other talks and posters on CBM, uranium, geothermal.

And that’s not all. Additional activities will include:

  • An EMD “open house” Tuesday night, featuring a talk on “Clean Coal Technologies” by William Ambrose that is open to all registrants or EMD members.
  • A two-day short course on CBM by Andrew Scott on both the fundamentals and the newest techniques for field evaluation (Thursday and Friday, Oct. 30-31).
  • A field trip to the Karoo coal fields of South Africa, including a visit to Grootegeluk coal field, the largest open pit colliery in the country (Monday-Thursday, Nov. 3-6).

Africa Energy, Global Impact is the convention’s theme, and the EMD clearly is well-positioned to deliver an excellent program that includes both the local flavor of the GSSA and the international expertise of the EMD.

We hope to see you at the convention, where you will be sure to experience one of the most exciting and rewarding AAPG international conferences ever.

Division Column-EMD

The Energy Minerals Division (EMD), a division of AAPG, is dedicated to addressing the special concerns of energy resource geologists working with energy resources other than conventional oil and gas, providing a vehicle to keep abreast of the latest developments in the geosciences and associated technology. EMD works in concert with the Division of Environmental Geosciences to serve energy resource and environmental geologists.

EMD has something very special planned for the upcoming AAPG International Conference and Exhibition in Cape Town, South Africa: an entire day of EMD-related events and activities.

We’ve asked Jeff Aldrich, this year’s international meeting’s general vice chair and also EMD’s African Region councilor, to provide a preview of all that is planned.

Although the linkages among surface sediments, geomorphic forms, and hydrodynamics in Holocene ooid tidal sand shoals have been evaluated recently, how these factors are reflected in the geomorphic evolution and stratigraphic record of shoals is less constrained. Yet, such understanding is essential to developing meaningful predictive conceptual models of three-dimensional architecture of ancient reservoir analogs. Integrating remote-sensing imagery, high-frequency seismic data, and core characterization from Lily Bank, a modern tidally dominated Bahamian ooid shoal in which sedimentologic processes are well documented, reveals the stratigraphic record of geomorphic change. An irregular, gently dipping rocky surface (interpreted as the top Pleistocene) with no pronounced topographic high underlies the Holocene oolitic succession. A 6-m (20-ft)–thick poorly sorted, gravelly muddy sand with few ooids overlies this basal surface. This lower interval is overlain by sand with an upward increase in proportion of ooids, sorting, and grain size. The uppermost unit, present only under active bar forms, is well-sorted oolitic medium sand with accretionary foresets. Sediments vary stratigraphically and geomorphically; the lower unit is finer and less well sorted than the upper units, and in the oolitic upper unit, sediment size and sorting on bar crests are distinct from bar flanks. Collectively, these results suggest that a marked antecedent bump is not necessary for occurrence of ooid shoals and that the stratigraphic record of analogous ooid shoal systems may preserve clues of geomorphic position, as well as geobody size and orientation.

We use samples from undeformed and deformed sandstones (single deformation band, deformation band cluster, slip-surface cataclasite, and fault core slip zone) to characterize their petrophysical properties (porosity, permeability, and capillary pressure). Relationships between permeability and porosity are described by power-law regressions where the power-law exponent (D) decreases with the increasing degree of deformation (strain) experienced by the sample from host rock (D, sim9) to fault core (D, sim5). The approaches introduced in this work will allow geologists to use permeability and/or porosity measurements to estimate the capillary pressures and sealing capacity of different fault-related rocks without requiring direct laboratory measurements of capillary pressure. Results show that fault core slip zones have the highest theoretical sealing capacity (gt140-m [459-ft] oil column in extreme cases), although our calculations suggest that deformation bands can locally act as efficiently as fault core slip zones in sealing nonwetting fluids (in this study, oil and CO2). Higher interfacial tension between brine and CO2 (because of the sensitivity of CO2 to temperature and pressure) results in higher capillary pressure and sealing capacity in a brine and CO2 system than a brine and oil system for the same samples.

With the growing global attention in shale gas and shale oil plays there has been a renewed interest in source rock geochemistry. This has resulted in a number of key questions concerning source characterization, including: 1) how much internal variability might be anticipated; 2) what is the potential impact of the variability on resource assessment; and 3) how best may a source be sampled to "fully" understand its variability?
