The WA Branch of the Australian Society of Exploration Geophysicists invites you to quickly register for our upcoming events:

See a live demonstration and learn about all of the facets of a drone magnetic survey. Adam Kroll will discuss two different drones, how they operate, the magnetometer bird and their specifications, we will fly a drone on a short magnetic survey and process the data live.

Adam Kroll graduated with BSc Hons Geophysics from Curtin University in 2002. Adam has worked as a geophysicist for mining companies, geophysics consultancies and government in the minerals and oil and gas sector. Adam founded Shift Geophysics in 2011, developed a magnetic gradient sensor on unmanned airship and later founded AirGeoX which have four crews operating drone magnetic surveys around Australia.

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.

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

Registration: https://us02web.zoom.us/webinar/register/WN_aHzlwiLpRRy6hKzdpx_JRw

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. 

Bio:

Michinori Asaka started his career as a geophysicist with INPEX in 2009. He worked for various geophysical problems including AVO analysis/inversion, rock physics, 4D seismic feasibility study, structural interpretation, and depth conversion. In 2018, he joined the PhD programme in Geophysics at Norwegian University of Science and Technology, Trondheim, Norway. He completed his thesis focusing on practical applications of elastic anisotropy in rock physics, rock mechanics and seismic reservoir characterization in 2022. He is currently working for INPEX where he continues working on reservoir characterization. 

Title: Machine Learning solutions to seismic processing challenges.

Speaker: Amarjeet Kumar

Date: Thu., 30 June 2022

Time: 5:30 pm – 7:30 pm AWST

Location: Mayfair Lane, 72 Outram St, West Perth, 6005

WA Branch's upcoming event where Amarjeet Kumar will talk on Machine Learning solutions to seismic processing challenges.

About this event

Machine learning (ML) has been attracting a large amount of interest lately in many industries. In seismic data processing, machine learning offers the potential to provide productivity gains through automated testing and QC. In this talk, we will briefly discuss the principles of supervised machine learning and demonstrate its application to various seismic processing challenges. The results show that machine learning-based solutions could soon become a useful tool for seismic data processing. No prior knowledge of machine learning is required to attend this talk.
