PESA SA/NT February Luncheon- Revisiting the rocks and seismic discovers turbidites and a new exploration play in the Penola Trough, Otway Basin, South Australia

Thursday, 29 February @ 12:00 pm - 2:30 pm (Australia/Adelaide time)

$25.00 – $75.00

Guest Speaker(s): Sharon Tiainen and Rob Kirk

Sharon Tiainen has 30 years’ experience in the upstream oil and gas industry working for Santos, Mobil, ARC Energy, Nido Petroleum, ADX Energy, HOT Engineering, and most recently joined the South Australia Department for Energy and Mining. From her own company PERM Consulting, she has consulted to Glencore, Lundin, OMV, Schlumberger, Shell, Woodside, and others. Prior to returning to Adelaide, she lived and worked in Melbourne and Perth and spent a decade in Austria, living and working in Vienna and the lesser-known Leoben. She has worked acreage in Algeria, Austria, Australia, Ecuador, Germany, India, Libya, Malaysia, Morocco, Myanmar, the Netherlands, Norway, Papua New Guinea, Pakistan, the Philippines, Romania, Tunisia, Turkey, the United Arab Emirates and the United Kingdom and is a member of SPE and PESA. Sharon specialises in building geological models including estimating porosity and permeability and determining gross depositional environments using only drill cuttings.

Rob Kirk is a consultant living in Yankalilla. He graduated from the University of Adelaide (BSc Hons) and the University of WA (MSc) combining geology with geophysics. He has four decades of industry experience in seismic and sequence stratigraphy having worked with SA Oil and Gas, Occidental, BHP, and Woodside living in Adelaide, Melbourne, Perth, London, Bogota, Colombia and Bakersfield, California, with the remainder consulting from Tasmania and South Australia. He has worked some 40 basins worldwide and has given public and inhouse industry courses on seismic stratigraphy for 30 years. Rob jointly won the 1991 AAPG Best Paper Award, was 1993 and 2014 PESA Distinguished Lecturer, 1994 Keynote Speaker at GCSSEPM, Houston and has had regular articles in the PESA Journal. He is a member of PESA and the AAPG. Rob specializes in seismic stratigraphy and sequence stratigraphy.

Revisiting the rocks and seismic discovers turbidites and a new exploration play in the Penola Trough, Otway Basin, South Australia

This rock-based and seismic-backed turbidite interpretation provides an alternative to the current alluvial channel/crevasse splay model for reservoir deposition and as such presents a new exploration play. Further the reservoirs immediate lateral association with gas/oil-prone source rocks and seals in the clay-rich lithologies potentially provide for stratigraphic trapping in addition to the previously targeted fault-controlled structural traps. By revisiting legacy core and seismic data, and integrating and iterating across multiple disciplines, a new and fertile turbidite exploration play has been identified.
