Quiacito™ Multiphysics: A case study in seismic and potential fields integration

Quiacito™ Multiphysics: A case study in seismic and potential fields integration

Tom McNamara*, Jarrod Dunne and James Parsons

Integration is often discussed in loose terms, more as an idea than a practice – but as exploration turns to more deeply buried resources, exploration strategies have become more complex and more complete data is needed. Model confidence has become more important and harder to achieve than ever. In simple systems, one form of data may be enough, but with complexity and noise, the non-uniqueness of geophysical modelling becomes a liability. Integrated modelling is becoming a necessity to manage exploration risks. It’s standard that where multiple forms of data are available, they should be cross-checked to see if they agree. Multiphysical modelling takes the next step and facilitates truth-checking across multiple forms of data for the same model, in the same workspace.

Integrated modelling for geophysical data operates on the principal that there is only one ground truth. Whatever property is surveyed, if the rock properties are properly measured and the geology is properly modelled, the data will agree across forms of data, and if it doesn’t, the whole story isn’t being told. Where one form of data is limited, another can complement its ambiguities. The lateral ambiguity inherent to seismic methods can be constrained by the lateral resolution of potential fields data, and likewise seismic can resolve the vertical ambiguity of potential fields. By modelling geophysical datasets simultaneously, the probability space for models that fit the data is reduced to only the intersection of solutions for each dataset.

Modelling in Quiacito is constrained by rock physics, leveraging knowledge from the mature science of seismic amplitude interpretation (AvO) in petroleum exploration. Lithological, petrophysics-driven compaction models inform velocity and density, which inform seismic and gravitational response. The software acts as a real time profile ‘whiteboarding’ tool to quickly create geological models and simulate their geophysical responses. Seismic data can be modelled to calculate a gravity profile, or a gravity-based model can be adjusted to match the seismic response using synthetic seismograms. As well as geological modelling, Quiacito has applications in generating geomechanical models that simulate overburden stress, and in iteratively improving velocity models for seismic imaging. Further multiphysics integrations are in development including magnetic and resistivity methods.

The talk explores the rationale behind data integration, from the operational level to the data modelling and interpretation, as well as the process of developing Quiacito and its place as a home-grown tool. Lessons from its development and consideration of its benefits and limitations give a view to the current state of data integration in exploration, and the role that integration needs to fill in the changing exploration landscape.

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.

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.
