Laurence Letki’s presentation highlighted wave-equation based techniques, such as full waveform inversion (FWI), as an integral addition to the modeling toolbox. The talk demonstrated how modern computing power allows the use of high frequencies in FWI and the resultant resolution of finer details. The presentation was held at “The George” on Tuesday 21st May. Many thanks to Discover Geoscience, our evening talk sponsor.

PESA WA May Branch Luncheon
“If you’ve got an unconventionals focused geologist in your company, go talk to them, you might be surprised at the learnings applicable to conventional hydrocarbon accumulations”. That was the takeaway from Avon McIntyre’s WA Branch May luncheon talk - “Bursting Source Rock and Strange Hydrocarbon Occurrences Around the World”. The presentation challenged attendees' thoughts on maturation, migration and charge-timing (all may be later than we think) through analysis of unconventional geology. Photos of explosively delaminated source rocks and abandoned gilsonite mines complimented an excellent talk. Many thanks to Spectrum, Searcher and DownUnder Geophysical for sponsoring the event.

CGG Begins First Multi-Client Ocean Bottom Node Survey in Mississippi Canyon, Gulf of Mexico
CGG has announced commencement of its first multi-client ocean bottom node (OBN) survey, taking CGG’s offshore data library to the “next level of excellence”. Located in the north-central region of the Gulf of Mexico, this dense OBN survey will provide well-sampled, full azimuthal coverage with long offsets, to deliver exceptional data for imaging the geologically complex structures in Mississippi Canyon, CGG said. Acquisition services are being provided by Seabed Geosolutions and the data will be processed by CGG Geoscience’s Subsurface Imaging in Houston.

Future plans in WA to lower costs without compromising service
Lower revenue, lower costs and maintaining strong safety, reliability and service performance are thenfocus of proposed future plans announced recently for Western Australia's Dampier to Bunbury Natural Gas Pipeline (DBNGP) and its customers out to the year 2025.

AGIG's Chief Customer Officer, Andrew Staniford, said the Draft Plan released outlines DBNGPmactivities and expenditure proposed to be undertaken from 2021 through to 2025.

APPEA welcomes Australian wholesale gas prices that are below Asian average
Australia’s average gas prices are amongst the lowest in Asia, according to the latest international survey of wholesale gas prices. The 2019 International Gas Union’s Wholesale Gas Price Survey shows the average wholesale gas price in Australia last year ($US4.54/MMBTU) was about 40 per cent less than the average wholesale price for the Asia‑Pacific region. The Australian price was also around one-third less than the average wholesale price in Asia. Australia’s leading trade partners Japan, South Korea and China all paid average wholesale gas prices over $US8 and in some cases approaching $US12/MMBTU.
