On the 8th of November we'll be welcoming Dr Gerrit Olivier the Director of Planetary Geophysics at Fleet Space Technologies and this will be held from 5pm at "Hello Gorgeous", in Newstead. Bookings here.

Finger food from 17.15

AGM from 18.00

Technical Talk from 18.15

Virtual (Zoom) registration: https://us02web.zoom.us/webinar/register/WN_e1ujI7WXSbahCW2Uowuc3g

Gerrit's talk will be: 

Using real-time seismic nodes to explore the Earth, Moon & Mars

As most of the outcropping and shallow mineral deposits have been found, new technology is imperative to finding the hidden critical mineral deposits required to transition to renewable energy. In this talk I will show Fleet’s progress in developing seismic technology to image the subsurface in real-time to address this challenge in an environmentally-friendly manner. I’ll also discuss our ambitions to deploy compact geophysical rovers on the Moon and Mars to image the subsurface to find resources for future colonisation missions.

Overview:

Mantle convection is an essential driving force of plate tectonics. It affects the horizontal and vertical motion of the Earth’s surface. The horizontal motion of the lithosphere is observed in the spreading rates, while its vertical motion leaves an imprint the geological record. In particular, positive surface deflections driven by mantle convection create erosional/non-depositional environments, which induce gaps in the stratigraphic record (i.e., hiatus). Modern digital geological maps allow us to map no-/hiatus surfaces at continental scale systematically and use them as a proxy for mantle flow induced dynamic topography. We find that hiatus surfaces change in timescales of geological series. This is consistent with the presence of a weak upper mantle. Also, we find significant differences in the spatial scale of inter-regional hiatus, on the order of 2000-3000 km in diameter, which can be linked by fluid dynamic analysis to active upper mantle flow regions. Our results highlight the importance of geological datasets to further understand geodynamic processes in the deep Earth. Also, they indicate that studies of horizontal and vertical motion of the lithosphere to track past mantle flow would provide powerful constraints for adjoint based geodynamic inverse models of past mantle convection.

The PESA QLD Symposium is a full day event focused on bringing together members of the Petroleum exploration and production industry here in Queensland. Local and International specialist speakers are invited to present a series of papers which address the industry activity within the state from a technical, economic and social perspective.

Hear from The Queensland Department of Resources, University of Queensland Centre for Natural Gas, Geoscience Australia, Bridgeport, State Gas, Blue Energy, Comet Ridge and others!

Ice Breaker Event
PESA QLD are hosting an Ice-Breaker networking event on the evening before the Symposium on Thursday the 8th of September.
The venue for this event is the Arbour Bar & Veranda – The Plough Inn, Southbank, only a short walk from the Convention Centre.
This excellent social event kicks off the Symposium proceedings, giving all delegates time to network with their fellow attendees and speakers in a more relaxed setting.

WA Branch talk: Geomechanical and petrophysical properties of rock salt for energy/gas storage

Thursday, September 29, 2022
1730
2000

WA Branch's upcoming event where Mustafa Sari will talk on Geomechanical and petrophysical properties of rock salt for energy/gas storage.

Title: Geomechanical and petrophysical properties of rock salt for energy/gas storage

Presenter: Mustafa Sari, CSIRO Energy

Registration: https://www.eventbrite.com.au/e/aseg-wa-branch-event-sept-2022-tech-night-tickets-401605391537

Date: 29/09/22

Time: 1730 - 2000 AWST

Location: The Shoe Bar and Cafe, 376 - 420 Wellington Street, Perth, WA 6050

About this event:

We evaluate of the suitability of the Frome Rocks salt dome for waste disposal or energy storage in deep boreholes, i.e., depth > 600m in the Canning basin, Western Australia(McNee et al., 2021). This evaluation involves the characterization and testing of the petrophysical, mineralogical, microstructural and geomechanical properties of rock salt samples from two contrasting facies in this formation: a shallower (800m) heterogeneous facies with 40% halite and 38% of dolomite inclusions (mm to cm in size, see figure); and a deeper (1100m) homogeneous, halite-rich facies. The petrophysical testing involves porosity, and gas permeability estimation as a function of effective confining pressure; and the geomechanical testing involves multi-stage triaxial testing at four distinct effective confining pressures (see figure), one of which corresponds to the estimated in-situ effective pressure prevailing at the depth of recovery of each sample (purple curves, see figure). The other stages simulate possible stress perturbation associated with drilling/excavation operations in the native formation.

During each stage of the multi-stage triaxial test, additional gas permeability tests are conducted under hydrostatic and deviatoric stress conditions; and creep tests are conducted under deviatoric stress corresponding to 75% of the yield stress at that depth. The laboratory data show that the homogeneous (heterogeneous) salt facies exhibit a porosity in the range 0.8-1.1% (0.2-0.3%), and a gas permeability in the range 50-500 mD (1-20 mD) in the confining pressure interval 0-16 MPa. Subsequent triaxial testing of the samples lasted about 80 days for each facies sample, essentially due to the time-consuming nature of the multiple gas permeability and creep tests conducted during each test.

A predictive anisotropic rock physics model of shale and its practical applications

Title: A predictive anisotropic rock physics model of shale and its practical applications

Presenter: Dr. Michinori Asaka

Date: Thursday, 6th October 2022

Time: 1400 - 1530 AWST

Abstract:

Elastic response of rocks often depends on the rock’s orientation, i.e., most rocks are anisotropic. In particular, shales which are the overburden rock in most of conventional oil and gas fields, often show strong elastic anisotropy due to alignment and platy nature of its constituent mineral. Various anisotropic rock physics models have been proposed to predict the elastic anisotropy of shales, however, practical applications are limited and most of rock physics models in the past do not follow the observed internal structure of shales and bound water properties suggested by existing studies. A predictive rock physics model of shale is developed by combining existing theories. Properties of locally aligned clay platelets, called domains, are calculated using a model based on the anisotropic Hashin-Shtrikman estimates. The effect of domain orientation is then accounted for by the orientation distribution function of domains. This model is consistent with the observed internal structure of shales and allows the finite shear stiffness of bound water to be taken into account. The applicability of the model was investigated using existing core measurements. The results imply that the model can be used to predict anisotropy parameters from limited information.
