SUMMARY:PESA ACT/NSW August Technical Lunch
DESCRIPTION:Federal Government False Narrative About Cause of East Coast Gas Supply Shortage\, Gas Price Cap and Gas Reservation\nI have major concerns about the prevalence of misinformation spread by politicians\, leaders at the UN and the media. Evidence-based decision making has been replaced by emotional beliefs\, with politicians and senior bureaucrats spreading false information without being held accountable. The mainstream media prioritises sensational news over evidence-based reporting and avoids conducting in-depth research. The ABC and SBS\, two taxpayer-funded media outlets\, solely presenting one-sided and propagandistic reporting rather than a balanced\, evidence based narrative. \nThe reason for recent high natural gas prices and supply shortages in eastern Australia has falsely been blamed by Anthony Albanese and his Labor Government Ministers on the war in Ukraine. \nGas price increases began before the Russian invasion of Ukraine and the 2022 price spike was caused by local factors. The Federal Government then used the excuse that the gas shortage and higher prices were caused by the war in Ukraine to justify implementation of new legislation that enforced a gas price cap and domestic gas reservation. This presents as a socialist intervention. \nMisinformation is prevalent in politics\, the media and Government discussions about gas prices. Evidence-based facts are overlooked in favour of emotional narratives.\nThe increase in east coast gas prices can be attributed almost solely to a domestic gas supply shortage. That gas supply shortage has been caused by State Government energy policies.\nThe ACCC’s gas report reveals that domestic gas contract prices increased from late 2020 to mid-2021 and the supply outlook from 2022 onwards appears tight.\nThe 2022 Australian Energy Regulator “Gas Markets” report highlights a period of sustained high gas prices and tight supply in east coast gas markets. Factors such as depleting southern gas reserves\, overlapping electricity market dynamics and short-term spot exposure during the higher demand winter period contributed to the increase in gas demand and subsequently gas prices. \nThe blame for the gas supply shortage can be attributed to past and present State Governments in NSW\, Victoria\, SA\, and Queensland who have limited access to new petroleum exploration areas through regulations\, lack of expedited approvals and withholding vast areas prospective for gas exploration.\nThe absence of a coordinated national energy policy\, combined with subsidies for renewable energy projects has resulted in a shortage of reliable\, low-cost base load electricity which in turn has increased electricity prices and gas supply shortages. \nThe false narrative surrounding human-caused climate change has directly led to policies condemning fossil fuels and limiting onshore petroleum exploration. The finance sector’s withdrawal of funding for fossil fuel projects\, the abandonment of support by business groups and the lack of defence by petroleum exploration and production companies has also contributed to the situation. \nContrary to the narrative\, the Australian export LNG projects were not robbing gas from domestic supply. These projects were developed for the existing\, lucrative LNG export market in Asia\, where prices were higher and long-term contracts were more feasible. The small domestic east coast gas markets were adequately supplied by other domestic sources and the large gas reserves associated with LNG projects could not have been sold in Australia due to the small market size.\nThere is an urgent need for a coherent national energy policy incorporating a balanced approach to renewable energy and an orderly transition to ensure a reliable energy supply and mitigate the impact of rising gas and electricity prices.\nLegislative power for petroleum exploration and production in onshore areas\, including State-controlled waters\, is governed by each State and Territory under the Australian Constitution. \nThere has been significant depletion of existing onshore gas fields through production in South Australia\, Victoria\, and Queensland and also in the offshore gas fields Victorian\, South Australia and Tasmania. These gas fields are in many cases approaching the final stages of their production life and with the declining production rates comes increased production costs which is passed on to the consumer in the form of higher gas prices. \nThe lengthy and costly State Government regulatory processes\, community consultations and bureaucratic obstacles faced by petroleum exploration companies have all hindered the addition of a new gas supply. These processes often lead to delays and unnecessary costs which are ultimately either borne by exploration company shareholders or in the case of successful projects are funded by consumers through higher commodity prices. \nNew South Wales (NSW) petroleum exploration was effectively halted in 2011 initially in response to the Government responding to activists claims of the damage caused by the use of fracking. The NSW Government then conducted a review of petroleum exploration resulting in the cancellation of all existing petroleum exploration licenses except for those related to the Santos-controlled coal seam gas project in the Narrabri region. \nThe NSW Government referred to the cancelled licences as “zombie licences” claiming that they had all passed their expiry date or had not met their financial commitments. In fact\, the NSW Government had applied a compulsory moratorium on exploration in 2011 which prevented the titleholders from meeting their financial commitments by conducting exploration activities. \nApplication for development approval of the Narrabri Gas Project was first submitted in 2014 with conditional approval not granted until September\, 2020 – a 6 year process!!! In the meantime NSW has no domestic gas supply and is totally dependent on gas imports from South Australia\, Queensland and Victoria\, a rapidly dwindling gas resource. \nPetroleum exploration and development policies in Victoria\, South Australia\, and Queensland has effectively halted onshore gas exploration and the addition of a new gas supply. Moratoriums and bans on onshore gas exploration and development in Victoria as well as the competitive tendering processes for new exploration areas in South Australia and Queensland have either stopped or greatly reduced gas exploration in those states. The Queensland government has prioritised the release of new areas for coal seam gas and unconventional gas leading to limited opportunities for conventional gas exploration. \nThe demonization of fossil fuels by state governments along with the withdrawal of prospective exploration areas has resulted in a gas supply shortage and increased gas prices on the east coast. Additionally\, the replacement of fossil fuels with heavily subsidized renewable energy sources without a proper transition plan is seen as a contributing factor to the gas supply shortage\, high gas prices\, and electricity grid imbalances. \nThere are major concerns with the long-term impact on the average citizen\, businesses and productivity due to government policies and subsidies that favour renewable energy over fossil fuels.

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
