Title: Shake, rattle and roll on. Seismology at GSWA

Speaker: Ruth Murdie

Time and Date: 09 Nov 2023, 5:30 pm

Venue: Shoe Bar & Café

Registration: https://www.eventbrite.com.au/e/aseg-wa-special-tech-night-by-ruth-murdie-tickets-709238249697

 

Abstract: 

Seismological projects have part of the operational research at GSWA for the past 10 years. Up to now, they have been quite low-key concentrating on imaging specific geological targets such as the Capricorn Orogen which investigated the collision between the Pilbara and the Yilgarn Cratons, the Albany-Fraser Orogen and the SE margin of the Yilgarn Craton, The Canning Basin and the area between the Western Australian Craton and the North Australia Craton. These studies have been in conjunction with geological mapping, active seismic and MT. 

Now we are conducting longer-term projects in conjunction with GA, such as baseline monitoring in the Canning Basin, seismicity of the Goldfields Region and more detailed monitoring of the SW Seismic Zone. 

However, the current big project, which we are in the first year of is the complete 40 km coverage of Western Australia with passive seismic stations, known as WA Array. This continues the work started in other parts of the country under the EFTF as AusArray. This is a 10-year project with a specific list of products, a tight timeframe and big ambitions.

WA tech night: High Density 3D seismic acquisition – An Illustrated Example from Onshore India

Title: High Density 3D seismic acquisition – An Illustrated Example from Onshore India

Presenter: Mick Micenko

Date and time: 26 Oct 2023, 1730

Venue: Shoe Bar and Cafe

Registration: https://www.eventbrite.com.au/e/aseg-wa-special-tech-night-by-mick-micenko-tickets-692140700467

 

Abstract: 

The world class Mangala oil field was discovered in Rajasthan in 2005. Even though the field had 3D seismic coverage the crest of the structure was poorly imaged and an experimental 2D seismic line was recorded across the crest later in 2004. This test line confirmed the benefits of using closer spaced source and receiver points and led to a high-density 3D survey being recorded across the field commencing in August 2006. Severe flooding in Rajasthan delayed recording for several months and the 120 square km survey was eventually completed in May 2007. Development drilling began in 2008 The HD3D was acquired with short station intervals with source and receiver spacing of 10m, increased vibrator frequency range using a single vibrator and effectively point receivers. This resulted in a 20Hz gain in bandwidth and improved signal- noise. The resulting seismic data had improved imaging of the shallow section which led to better depth migration and enhanced resolution of the structural complexities within the reservoir allowing more optimal positioning of the development wells. The Field began production in 2008 with oil initially being trucked until a heated pipeline was built to transport the oil 600km to the coast This talk will be illustrated with colourful pictures of life in India.

WA branch tech talk: Digital Rock Under Stress

Thursday, September 28, 2023

Title: Digital Rock Under Stress

Speaker: Professor Maxim Lebedev

Date and Time: 28 September 2023, 5:30 pm

Registration: https://www.eventbrite.com.au/e/aseg-wa-special-tech-night-by-prof-maxim-lebedev-tickets-692145885977

Abstract:

Modelling the physical properties of rocks based on microstructure derived from X-ray microtomographic images (known as digital rock physics) is an important technology in geophysical rock characterisation. However, these images are most commonly obtained at room pressure and temperature conditions. Consequently, most digital rock physics models are not representative of the rocks at depth.

Reservoir rocks are at such depth that they experience high stresses and temperatures. The thermodynamic properties of the fluids inside the reservoir are pressure and temperature-dependent; therefore, transport properties are also temperature and pressure dependent. Moreover, it is well established that elastic rock properties of rocks are strongly affected by stress and/or fluid distribution. Thus, to acquire realistic pore network structures and fluid distributions (including, but not limited to, residual saturation) and reliably estimate transport and elastic properties from micro images, rocks with fluids inside have to be imaged at reservoir pressure and temperature conditions.

In this lecture, we will discuss how to obtain 3D images under elevated temperature and stress conditions and the challenges with imaging and further image processing. Finally, we will provide some results to demonstrate how the microstructure of the rocks can be linked to the transport and elastic properties of rocks measured on bigger samples.

The lecture is useful to rock physicists, petrophysicists, and reservoir engineers.

Course description: Geoscientists and engineers are very comfortable using seismic data sets acquired with geophones, hydrophones, and accelerometers because we have a long, well-defined set of standards for acquiring, processing, and interpreting them. However, distributed acoustic sensing (DAS) seismic measurements are rapidly augmenting, and in some cases replacing, the data from these conventional tools. Technologists are frequently unaccustomed to using DAS seismic data sets since it directly acquires relative strain or strain rate measurements and not the more familiar pressure, displacement, velocity, and acceleration data. There are also acquisition parameter selections that must be made to optimize the acquired data to accomplish the purpose of the seismic survey. This course is designed to build an intuition and understanding of the value, limitations, and applications of DAS seismic technology. In addition to the lecture and accompanying book, software will be provided, which will allow the student to interactively explore DAS seismic technology.
