AAPG Asia Pacific Presents - Virtual Webinar Series

Greene and Coffa Featured in January Talks

American Association of Petroleum Geologists (AAPG)

AAPG Asia Pacific is proud to host two new AAPG Asia Pacific Presents talks, featuring Professor H. Gary Greene and Dr. Andre A Coffa.

AAPG Asia Pacific Presents is a collection of online presentations being offered free of charge. The 60-90 minute session will be conducted through Zoom, and will be followed by a short Q&A period, handled by a moderator. To register for one or both of these talks, click on the link(s) below. Registrations will be accepted on a first-come basis.

Volcanism, Deformation, and Fluid Flow Along the Queen Charlotte Transform Margin of Alaska, USA, and British Columbia, Canada

Thursday, 7 January 2021 • 10:00 AM (SGT) - Singapore Time Zone
Presented by Professor H. Gary Greene, Moss Landing Marine Labs, San Jose State University and President, Circum-Pacific Council

The Queen Charlotte transform (QC) fault system is a major structural feature that extends from near the Northern end of Vancouver Island, Canada, to the Fairweather Range of Alaska, where it connects to the Fairweather (FW) Fault system. The QC–FW transform marks the margin between the North American and Pacific plates. Until recently the QC fault system, exclusively located in the oceanic realm, was poorly mapped, but through the efforts of the USGS, Geological Survey of Canada, University of Alaska, and NOAA, the entire ca. 900 km length of the fault and its immediate surrounding seafloor have been surveyed using multi-beam echosounder and geophysical instruments. The data present a straight "knife edged" fault that appears to accommodate the majority of the relative plate motion along the primary strand of the system. However, extensive deformation associated with volcanism and fluid seeps are present throughout most of the length of the system. Elongated conjugate ridges, volcanic cones, and mud volcanoes are well imaged in the bathymetry and in seismic-reflection profiles. Multiple fluid sources including thermogenic-formed fluids from hydrocarbon basins are speculated. Seafloor structures and geomorphic features formed on the seafloor from volcanism and fluid flow provide valuable habitats for various organisms that live at depth in the region.

How Do You Explore? The Fundamentals of Play Based Exploration

Thursday, 21 January 2021 | 11:00 AM (SGT) - Singapore Time Zone
Presented by Dr. Andre A. Coffa, Pietrovin Consultants, Australia

Many small to medium oil and gas exploration companies search far and wide for opportunities. A successful exploration company has a clear strategy predicated on studying basins and plays in order to define the best prospects. Widely recognized by the major E&P companies, Play Based Exploration (PBE) is the leading way to explore for oil and gas. Simply put, PBE is a method to build and leverage an understanding of basins and petroleum systems based on hydrocarbon plays. PBE is an evaluation process aiming to understand the fundamental logic of HC plays, resulting in a thorough technical basis for ranking and prioritizing all exploration projects and activities. By focusing fist on the basin, then on individual plays and petroleum systems the exploration team focuses early on top tier, second tier, and least prospective areas of interest. The first step is to describe the regional context and the basin framework. In the subsequent play focus, petroleum systems are analyzed by quantifying risk in common segments. Overlaying the resulting common risk segments clearly focuses on prospective vs. non-prospective areas.
