PESA ACT/NSW July Technical Lunch

Tuesday, 11 July, 2023 @ 12:00 pm - 2:30 pm (Australia/Sydney time)

$10.00 – $75.00

Guest Speaker(s): Andrew Nelson

Andrew Nelson began his geophysical career in the Geophysics Section of GSQ in 1975, and helped perform seismic refraction foundation surveys for the planning of the Wivenhoe and Burdekin Dams, as well as working on BMR seismic surveys in the Galilee and Georgina Basins and Denison Trough. He then joined Shell in Perth, working on various Australian basins, and later worked a short stint with Delhi in Adelaide, going on to join Ampolex in Sydney where he worked mainly on the Ampolex interests in the BHP operated Timor Sea blocks, and on Papua New Guinea. Those were heady days when BHP contracted offshore rigs for multi-well programs for exploration, and for appraisal and development wells on discoveries such as Jabiru and Challis. Oil was discovered in PNG at what was then called Iagifu, by the Chevron operated Joint Venture, which included Ampolex, BP and Oil Search,. Oil Search in those days consisted of no more than a Board and Company Secretary, and drafting of figures for their Annual Report was provided by Amploex. It was at this time that Andrew expanded an interest in strike-slip structures and received the title Strike-Slip-Nelson. On leaving Ampolex Andrew consulted to companies such as Oil Search, InterOil, and Horizon, with a focus on PNG exploration and appraisal, and some time spent on Yemen. As Geophysicist for InterOil he managed PNG seismic and gravity surveys in areas many thought to be “moose pasture”, but which eventually yielded up the Elk/Antelope gas-condensate discovery. Under his geophysical management, InterOil was one of the first users of airborne gravity for petroleum exploration in this region, eventually surveying nearly all their acreage. At Horizon he contributed to the mapping and appraisal drilling of the PNG Elevala and Stanley gas/condensate fields, and interpretation of aeromag and gravity surveys. He retired in 2015 to enjoy sailing, golf, gardening, and grandchildren.

Household renewable energy journey, and more

What 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?

These 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.

Comparisons 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.
