Posamentier and Jackson to Kickoff AP Digital Events Series

American Association of Petroleum Geologists (AAPG)

AAPG Asia Pacific is proud to announce the first two sessions of AAPG Asia Pacific Presents, a collection of online presentations being offered free of charge.

Each hour-long session will be conducted through Zoom. Presentations will be followed by a short Q&A period, handled by a moderator. To register for one or both of these events, click on the corresponding links below. Registrations will be accepted on a first-come basis.

Applications and Workflows of Seismic Stratigraphy and Seismic Geomorphology Applied to Deep-Water Settings

Presented by Henry W. Posamentier
Posamentier Geosciences LLC, USA
Thursday, 21 May 2020
9:00 pm–10:00 pm (SGT)

Henry W. Posamentier discusses the application of 3-D seismic stratigraphic analyses to the mitigation of risk associated with lithology prediction prior to drilling – workflows and techniques. Principles and workflows of seismic stratigraphy and seismic geomorphology will be discussed and numerous examples will be shown from a variety of depositional settings.

When Salt Disappears: Why Should We Care About Welds?

Presented by Professor Christopher Jackson
Imperial College, United Kingdom
Thursday, 4 June 2020
3:00 pm–4:00 pm (SGT)

Salt welds form due to salt thinning by mechanical (e.g. salt-flow) and/or chemical (e.g. salt-dissolution) processes. Despite being ubiquitous in salt-bearing sedimentary basins, where they may trap large volumes of hydrocarbons, little is published on weld thickness and composition. As a result, we have limited knowledge of the seal potential of welds, and the fundamental kinematics and mechanics of salt flow and related welding. We here use 3-D seismic reflection, borehole, and biostratigraphic data from the Santos Basin, offshore Brazil, and the Atwater Valley protraction area of the northern Gulf of Mexico to constrain the thickness and composition of salt welds, and to test the predictions of analytical models for salt welding. We show that 3-D seismic reflection data may not resolve weld thickness, with the presence of relatively thin remnant salt lending support to models of welding based on viscous flow. The halite-dominated character of the weld also supports the hypothesis that tectonic purification may occur during salt flow.

Would YOU Like to be a FeaturedPresentsSpeaker?

We are searching for willing speakers from around the world to deliver short presentations (45 minutes to one hour) on one of the discussion topics below.

Each session may include pre-determined questions or open questions via the Zoom facility, depending on the particular talk and whether a synopsis of the talk is made available ahead of time.

If you are interested and would like to be a potential speaker, please complete and submit this form to AAPG Asia Pacific Programs Manager . The Asia Pacific Region Council will review all submissions and advise successful candidates in due course.

Discussion Topics:
  • Specialist, Expert or Thematic Talks
    Talks on different aspects of petroleum geology as a science by highly knowledgeable individuals who may be distinguished in their field.
  • Heritage of the Petroleum Geologist
    Talks based on years of experience by storytellers who have practiced their profession in the industry for most of their lives.
  • Oil and Gas – Our Business
    Talks on how we go about our business to find oil and gas accumulations that are essentially commercial to enable their development and production, including adjunct disciplines.
  • Association Matters
    Talks about AAPG, its past, and where it is going; including careers, mentoring, and business talks about the association.
  • Energy Transition
    What the role is of oil and gas over the next 40 years, and how it will mitigate further emissions of carbon dioxide into the atmosphere and prevent the further driving of greenhouse effects.
  • Country Files
    Talks are envisaged on a country basis, given by experts from that country with a story to tell about their oil and gas endowment, petroleum geology, and oil and gas industry.
  • Plays and Prospects
    Talks on the specific results of exploration and disseminating news about exploration endeavours to fellow petroleum geologists.
