PESA SA/NT Technical Luncheon, Thursday 24th June – Strike Energy: West Erregulla Update & PESA Prize Winner: Brittany McDermott

Thursday, 24 June, 2021 @ 12:00 pm - 2:00 pm (Australia/Adelaide time)

$20.00 – $80.00
Strike Energy West Erregulla

Guest Speaker(s): Andrew Farley (Strike Energy) and Brittany McDermott (PESA Prize Winner)

Andrew Farley graduated from the University of Newcastle (Australia) in 2002 with a B. Sc in Geology. He has 17 years of experience working with onshore oil and gas operators on exploration and development projects in all 5 mainland states of Australia. Prior to joining Strike Energy in 2012, Andrew worked with AGL Energy on the Camden Gas Project development, Silver Springs Underground Gas Storage Facility, and Surat Basin conventional exploration assets. Andrew has held the position of Manager Geoscience with Strike since 2014, and is responsible for all of Strike’s subsurface exploration activities. Andrew has been a key member of the Strike team during the design and execution of the Jaws Project in the Cooper Basin, and more recently the West Erregulla discovery in the Perth Basin. Andrew enjoys cycling and gardening, but by his own admission is yet to master either. Brittany McDermott was born and raised in Calgary, Alberta where she completed a BSc in Geoscience and a BSc in Biology and Chemistry at the University of Calgary in 2012. She began working in the petroleum industry as a Geologist and her journey has led her to work in various countries including Canada, USA and Australia for PennWest Exploration, Occidental Petroleum, California Resources, Rio Tinto, and Idemitsu. Her career began at the start of multiple downturns, so she recently decided to complete a master’s degree at the Australian School of Petroleum and Energy Resources to advance her career. She completed her thesis with Cooper Energy under the mentorship of Peter Boult, Mark Browne and Peter Strauss and received her Master’s in Petroleum Geoscience in December 2020. As a result, she accepted a vacation student position at Santos, where she is currently still employed. Brittany says going back to school was the best decision as it has strengthened her geological knowledge and enabled her to continue her petroleum career.

Andrew Farley:

ABSTRACT: West Erregulla Update

Since the discovery of the West Erregulla field in 2019, Strike has embarked on an aggressive three well appraisal plan moving to reserves and FID. Andrew will discuss the highs and lows of the appraisal campaign so far, what it means for West Erregulla, and the next big well South Erregulla 1 to be drilled later this year.

Brittany McDermott – PESA prize winner

ABSTRACT: Characterisation of Submarine Slides and Slumps in the Seaspray Group of the Gippsland Basin

The Seaspray Group, of the Gippsland Basin creates complex acoustic velocity architecture within the basin that makes accurate processing and time-to-depth conversion of seismic reflection survey data very difficult. As a result, interpretation of the underlying Latrobe Group petroleum reservoir system can become compromised. Reinterpreting depositional components of the architecture of the Seaspray Group may result in an improved acoustic velocity field for depth conversion.

The Seaspray Group shows evidence of sliding and slumping material, and this study aimed to characterise these submarine environment events. The key components of a submarine slide and the deposits they produce are; the presence of a ductile basal detachment surface, slide blocks have a crescent-shaped scarp of slide blocks and toe thrust front, presence of sediment rollover, downlapping reflectors, mass flow, and deposits exhibit evidence of rapid fluidisation caused by dewatering events. During the Mid-Miocene, the Gippsland Basin was a shelf margin basin that underwent a significant compressional tectonic event. This event would have provided the shear stress to create sliding as extensional relief formed atop the Seaspray Group generated by growing anticlines in the Latrobe Group below. Submarine sliding and slumping aligns as an explanation of the structural complexities seen in seismic imaging data of the Seaspray Group, and other evidence supports it as a possibility.
