SUMMARY:PESA WA June Technical lunch talk - Monitoring of the reservoir pressure & saturation changes using Extended Elastic Impedance from time lapse seismic data: Enfield Field
DESCRIPTION:Hosted with thanks to our Platinum sponsor SLB \n  \n \nGold Sponsors Katalyst Data Management\, Applied Geoscience\, Delft Inversion and DUG \n                \n                                                \nand Silver Sponsor Qeye \n \n  \nPESA WA invites you to our technical luncheon on Thursday 15th June\n\n“Monitoring reservoir pressure and saturation changes using extended elastic impedence from time lapse seismic data: Enfield Field\, NW Australia”\nPresented by Sergey Shevchenko\, SIS Exploration Pty Ltd\nThe Extended Elastic Impedance (EEI) concept has been used by the oil industry primarily for lithology and fluid prediction. We present a method of reservoir monitoring that calculates changes in pressure and saturation in a producing reservoir by applying EEI to time-lapse seismic data. The method uses time-lapse seismic difference data rotated to specific EEI χ angles which are optimised for the changes expected in a given reservoir. One angle is found to be appropriate to identify predicted changes in saturation\, using fluid substitution models\, while the other angle is found from rock-physics assumptions or laboratory measurements of fluid-pressure changes. \nOur technique is tested using time-lapse seismic data for the Enfield oil field\, in the North West Shelf\, Australia\, with estimates of optimal EEI rotation angles χ based on log data and Biot-Gassmann modelling for the fluid changes\, and on rock physics models fit to measurements made on core samples for the pressure changes. Reflectivity and inversion domains were used using various approaches to test results qualitatively and quantitively. \nThe final calculated pressure and saturation maps predicted areas where changes in pressure and/or saturation changes were expected. It was successfully tested with two areas of changing the pressure from the well data\, showing that our quantitative results are credible. Additionally\, our results coincide with the Enfield operator’s maps for pressure and saturation predictions. \n  \nTicket Prices: \nMember (Early Bird): $69.00 \nConcession Member [Retired\, Graduate or Hardship] (Early Bird): $59.00 \nStudent Member (Early Bird): $39.00 \nNon-Member: $99.00 \nMember (Non-Early Bird): $79.00 \nEarly bird pricing ends Thursday (1 week prior) at 5pm (AWST). All ticket sales close at 5pm Tuesday (2 days prior). \n  \nRefund Policy: Refunds are only applicable if notified in writing to WA-secretary@pesa.com.au prior to the close of ticket sales. Refunds will be issued to all participants in the case that government regulations prevent the event taking place.

SUMMARY:PESA ACT/NSW June Technical Lunch
DESCRIPTION:THE FEDERAL BUDGET 10 MAY 2023\, ITS CONTENTS AND ITS IMPLICATIONS FOR THE ENERGY INDUSTRY\nThe Federal Budget is far from what is contained in the Treasurers Speech\, the associated Ministers Press releases\, the Budget documents themselves and the massive rhetoric that will flow from days after the actual speech in the House. There will be countless hours spent in preparing treatises and marketing documents from the many who feed off the circus and the media who have a vested interested in selling whatever. \nThe reality becomes a lot clearer when those with patience and tenacity actually spend time post delivery of the package of above by delving far deeper and working through both what is included in those documents and just as importantly what is NOT included. \nThis presentation given many days post the circus will address as many issues as become apparent with as much depth as is possible in a 30 minute talk\, both being advanced and provided in common language avoiding jargon. \nThe more publicised issues are going to include the changes to the Petroleum Resource Rent Tax rules and funding for hydrogen and renewable energy sources\, but that means there will be hidden stories for nuclear energy\, major infrastructure support\, graphite production and research into alternatives to lithium-ion batteries. The deliberate intention will be to make this session hum with ideas\, identified issues and positive thoughts of how Australia can “move forward”\, while keeping cost increases down for the masses. \nNotice: previous event on PNG Darai Limestone by Tony Allan cancelled\, apologies for any inconvenience caused. \nAGM Documents\n2023_PESANSW_Annual_Report \nPESA NSW 2022 AGM Minutes Draft \nPESA NSW Branch Committee Nomination Form 2023 \nPESANSWBranch-AGMNotice2023
