SUMMARY:PESA ACT/NSW July Technical Lunch
DESCRIPTION:Household renewable energy journey\, and more\nWhat is a VPP and how can you be part of one? Can you get electricity off the grid for free\, or get paid for taking it? Can you as an individual trade electricity? What is VTG or VTH\, and how will these revolutionise electricity supply in the future? Why is South Australia so far ahead in the renewables race\, and how was John Howard involved? How will the transition to renewables work in Australia\, and how long will it take? How much does it really cost to run an electric car? What percentage of electricity production is now renewable? \nThese and other questions will be addressed in this discussion of going all electric. Home solar systems provide the means to monitor one’s electricity generation and usage\, at 5 minute intervals. \nComparisons of different periods (days\, seasons\, years) allow the user to evaluate\, for example\, the effect of La Niña on solar production\, winter versus summer\, and the need for backup from the grid\, and to determine what device in your household is sucking up all that electricity. Even if you don’t have a solar system you can optimize your use of solar energy if you want to. Some weird and wonderful data displays from the Australian Energy Market Operator’s website will be shared\, comparing state by state energy generation by power source\, usage and price.

SUMMARY:PESA & ASEG QLD: Lunch Presentation\, 20th July – Randall Taylor
DESCRIPTION:This month PESA and ASEG welcomes Randall Taylor to present a technical luncheon entitled “Recent Exploration in the Timor-Leste Frontier”. \nThe Technical Lunch will be held at the Brisbane Hilton Hotel\, in the Victoria Room. \nFor detailed directions\, see explanation below. \n\n\n\nPresentation:\nRecent Exploration in the Timor-Leste Frontier\n\n\nVenue:\nHilton Hotel Brisbane\, 190 Elizabeth Street\, Brisbane QLD 4000\nVictoria Room\n(Detailed directions below)\n\n\nDate & Time:\nThursday\, 20th July 12:15 PM\n\n\n\n  \nPresentation Abstract: \nRecent Exploration in the Timor-Leste Frontier \nTimor Resources\, has re-commenced onshore hydrocarbon exploration in Timor Leste after a 50-year hiatus. This talk describes the challenges presented by the complex geology and the process of developing an understanding from the regional to the prospect scale. Timor Island is the product of an active continental collision\, which has been studied by numerous academics for decades. Timor Resources has harnessed some of their ideas\, added a few of our own\, and recently acquired 2 seismic surveys and drilled 3 wells in the Suai Sub-Basin on the southern coast\, including a deep “sub-decollement” play\, first proposed in the 1970s. The talk will show the regional structure developed using gravity and outcrop data and then zoom in to the prospect scale for a look at the recent drilling results. \n  \n\nTickets for the Technical Luncheon can be purchased below: \nEarly bird pricing will remain available up until Wednesday\, 12 July 11:30 PM after which\, standard pricing will come into effect. \nFinal numbers to venue required by Monday\, 17 July 12:00 PM – To avoid disappointment please register before that date and time. \n\n\n\n\nEarly Bird Ticket Price\nStandard Ticket Price\n\n\n\nPESA & ASEG Members – $55\nNon-Members – $77\nStudent / Retired Members – $33\nPESA & ASEG Members – $77\nNon-Members – $99\nStudent / Retired Members – $33\n\n\n\n\nThe venue location can be accessed by two means: \n1) Entry from Queen Street Mall\nEnter the lifts located just to the left of Mick O’Malley’s Irish Pub\, and take the lifts to Level 6.  Once you exit the lifts\, the Victoria Room is immediately to the left. \n2) Entry from Elizabeth Street\nEnter the foyer located on 190 Elizabeth Street\, and take the lifts to Level 6 (Main Foyer).  The Victoria Room is located in the back of the main foyer towards the right as you walk past Vintaged Restaurant. \n\n  \n\n\n\n\nKeep track of upcoming PESA QLD Events:\n\nClick here to view PESA QLD Events Calendar on the web\n\n\n\n\nClick here to subscribe to PESA QLD Events by adding it to your Google Calendar \n

SUMMARY:PESA SA/NT July Technical Luncheon
DESCRIPTION:A seismic source field trial in the Bass Strait: Testing the impact of several different source configurations on geophysical quality\, received sound\, and direct impact on scallops and lobsters\nPresented by: John Cocker (Beach Energy)\n\n  \nAbstract:\nBeach Energy acquired a seismic source technology field trial in Dec 2021 in the shallow waters (50-80m) of the Bass Strait. The trial consisted of eight source tests acquired along two 2D lines\, including: a full-size array (2480 cu.in.) with Sercel G-GUN II in a wide-tow triple source configuration\, eSourceTM (2098 & 1049 cu. in.)\, reduced size (300\, 700 & 1260 cu.in.)\, and Distributed Source tests including Shearwaters Apparition test (140 & 340 cu.in.). A test of a 70 cu.in. airgun was also recorded during a whale mitigation procedure. The aim of the field trial is to investigate whether any of these source options: \n1. Provide the required geophysical data quality \n2. Significantly alter the received anthropogenic sound levels (SPL and SEL) \n3. Changes the impacts on benthic invertebrates via analysis of scallop and lobster specimens placed on the seafloor \nThis combined data will then be used to determine if any of the alternative source options are suitable replacements for conventional full-sized arrays and if any provide a meaningful reduction to potential impact on marine organisms. \nThe study was performed in conjunction with the Institute for Marine & Antarctic Studies\, Fisheries Research & Development Corporation\, Curtin University\, and the Department of Natural Resources & Environment Tasmania. \nScallop and lobster specimens as a model species for crustaceans and molluscs were placed on the seabed below the full array (triple and single source)\, both eSource arrays and one control location. The specimens were assessed over 6 months for physical damage\, chronic effects and survival\, pH\, refractive index\, total and differential haemocyte cell counts\, DNA damage and biochemistry. Lobsters were also assessed for righting ability. The results will not be available until Q4 2023. Noise loggers were collocated with the specimens to measure received sound. \nThe data processing was completed by Shearwater. The results show that all options result in lower S/N raw shot gathers; but also\, that modern processing algorithms are able to compensate for most of this through noise attenuation\, deblending and designature. eSource (2098 and 1049 cu.in.) and the reduced source size options provide very similar final stack and migrated gather quality to the full array. Both apparition tests (140 & 340 cu.in.) were very similar in 2D stack quality but with slightly lower S/N below 4Hz and above 64Hz. The data quality of the other distributed source tests was better in the shallow but worse in the deep due to poor randomisation achieved. There are differences in gather quality that require further investigation. These results demonstrate that alternative sources and/or smaller volumes have the potential to meet survey objectives whilst reducing impact on marine life. \n  \nEvent Details:\nThursday\, July 27th\, 2023 \nLuncheon: 12 pm for a 12:30 pm start \nPlace: Ayer’s House\, 288 North Tce\, Adelaide \nIncludes a 2-course lunch and drinks \nBookings close Tuesday\, 25th July\nAny late bookings will incur an additional $20 fee. Strictly no walk-ins.\n
