Basin-Floor Fan Systems (South Central Pyrenees, Spain)

Steve CosseyINSTRUCTOR: Steve Cossey, PhD
DISCIPLINE: Field Courses
CEUS: 4.0




WHO SHOULD ATTEND: Geologists, geophysicists, members of deepwater study teams (engineers, team leaders and project managers), as well as mid-level to upper-level managers needing to learn more about deep-marine systems, architecture, elements, reservoir properties and their explanation and production characteristics.

COURSE DESCRIPTION:This field course is designed for explorationists, non-geoscience members of a synergistic team and managers interested in developing an understanding of deep-marine foreland basin-floor fan systems. From seismic-scale to bed-scale, the architecture, elements and reservoir characteristics of well-exposed deep-marine channelized fan systems are studied in the South Pyrenean foreland basin which is associated with synsedimentary tectonics.

The importance of seafloor topography in controlling fan sedimentation, as well as the evaluation and significance of sediment-slide/debris flow fan system complexity is studied. In evaluating deep-marine processes, environments and systems, you will learn how to consider their application to hydrocarbon exploration and production.
