CANCELLED – PESA WA March evening talk – Stratigraphic analysis of sediment gravity flow deposits and implications

Thursday, 19 March @ 6:00 pm - 8:00 pm (Australia/Perth time)

Free – $30

Guest Speaker(s): Jon Rotzien

Jon Rotzien is President of Basin Dynamics, a US based consulting and exploration company. He has published peer-reviewed research papers and conference proceedings pertaining to petroleum geology, reservoir characterization, sequence stratigraphy, basin analysis and geophysics, and he consults for the oil and gas industry on all oil-producing continents. Since 2017, he has delivered courses designed for AAPG and its partner societies OTC and GCAGS in Houston, Bakersfield and San Antonio. He is a Distinguished Service Award winner of GCSSEPM (2018), associate editor of the Bulletin of Canadian Petroleum Geology and co-founder of the Houston Explorers Club, a leadership forum for young energy industry executives. Mr. Rotzien received a Ph.D. in Geological Sciences from Stanford University and a B.A. degree in Geology from Colorado College.

PESA WA invites you to our March technical evening talk on Thursday 19th March

“Stratigraphic analysis of sediment gravity flow deposits and implications”

Presented by Jon Rotzein


We provide a field-based analysis of the range and variation in deep-water siliciclastic conventional petroleum reservoirs. This presentation explores new themes in petroleum reservoir research and applications, as well as approaches to classic reservoir challenges and how they’re being addressed today. We explain why these technical challenges are relevant to exploration, appraisal and development drilling programs. This analysis questions the turbidite reservoir paradigm established since the 1960s and provides a route to modern solutions:

  • What is the range & variability in the types of clastic conventional petroleum reservoirs?
  • What are the key factors determining sediment distribution patterns in the deep sea?
  • How can first principles of stratigraphy be used to a company’s advantage when determining depositional environment, and, in turn, bulk rock volume, net to gross and porosity as part of the original oil in place equation?
  • What is the role played by sedimentary routing systems in determining the overall quality of turbidite reservoirs?
  • How can we as an industry simultaneously and at various scales observe sediment gravity flows and their deposits to inform business decisions?

The main processes in deep-water regions include pelagic and hemi-pelagic sedimentation, mass movements, ocean currents, tides, waves and biological processes. Some of the main deposits that function as petroleum reservoirs include deposits from turbidity currents (A, B, C), debris flows (D), and flows that experience both fluid turbulence and matrix strength, such as slurry flow deposits, hybrid event beds, transitional flow deposits or argillaceous sandstone beds.
