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



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.


Maxim is a Professor at Edith Cowan University, Australia. Maxim was awarded BS, MS and PhD degrees from the Moscow Institute (State University) of Physics and Technology in Russia. He has over 30 years of research experience in physics, material science and rock physics, working at leading research organizations in Russia, Japan, New Zealand, and Australia.

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.

James (Jim) Dirstein studied Geology and Geophysics at the University of Toronto. For more than 40 years he has enjoyed working as a geophysicist on many resource projects in Australia and overseas. In addition to his project work, Jim has played a role in the commercialization of several transformative technologies. During his career, these efforts   have involved working as an early adopter, angel investor or collaborator, in the fields of time series analysis, digital surface analysis along with a patented airborne acquisition system and a fully trained and patented Artificial Intelligence (AI). Outside of the realm of geophysics Jim has presented papers at metallurgy conferences on the role of microbes for in-situ mining, minesite remediation, Carbon capture and using microbes for permeability enhancement and the production of Hydrogen.


The art of data interpretation is about finding patterns in data. Finding patterns requires careful observations. Human beings are very much visual creatures with our perception of the world based upon what we can see. Unfortunately, traditional interpretation methods are often biased by our senses as well as pre-existing ideas. Therefore, the combination of confirmation bias, along with things we “don’t see” distorts our perception of reality. Often data we are tasked with interpreting is presented to us a surface. This surface could be a digital elevation map or more likely data from remote sensing methods such as Potential Fields, Radiometrics or Seismic attributes, etc. As geoscientists we are always looking for ways that help us to organise information into more meaningful formats, enabling both accurate and time efficient reviews of data. Moreover, since most of interpretation of the geophysical data we acquire is non-unique in nature, we need to consider workflows to help minimise this non-uniqueness.

Since a fundamental property of any surface is its geometric characteristics, the identification and extraction of these properties can reveal features and objects not easily identifiable by visual analysis alone. In 2013, a new method for digital surface analysis was introduced to address some of the limitations of traditional surface analysis methods. This mathematical solution applies a completely different approach without the use of existing techniques or algorithms. With this method, the analysis of a digital surface involves the calculation of a complete set of morphometric properties as it is defined by differential geometry (e.g. Dupin Indicatrix). The resulting database of geometric elements is queryable using a GIS style interface providing an attractive means to simplify and accelerate the data mining process.

This analysis technique was introduced to the ASEG at the 23rd International Conference and Exhibition, 11-14 August 2013 Melbourne, Australia. The presentation and extended abstract was entitled “Digital surface Analysis: -A new approach using differential geometry”.


While the 2013 publication provided background and several examples, our evening presentation will discuss several new examples and workflows from our use of this technology over the last decade.

Drinks and nibbles will be available from 5:30pm - 6:15pm. The talk will commence promptly at 6:15pm. The ASEG WA thanks our sponsors for their continued support.

ASEG WA tech night: Surface and borehole seismic monitoring of CO2 geological storage

Thursday, April 27, 2023

Title: Surface and borehole seismic monitoring of CO2 geological storage

Speaker: Professor Roman Pevzner

Date and time: 27 April 2023, 5:30pm

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



Geological carbon capture and storage (CCS) or sequestration is a critical component of CO2 emission reduction, which aims to alleviate global climate change. Geological carbon storage always requires a subsurface monitoring program to address two main goals: (1) surveillance at the reservoir level to verify compliance of the growing CO2 plume with the original plan and (2) early detection of adverse effects, such as leakage of the injected fluid from the containment zone or significant induced seismicity associated with the injection.

Seismic methods play an important role in achieving both goals. Change in CO2 saturation in the pore space inside of the storage reservoir or in the overburden results in the change of elastic properties detectable through changes in seismic reflectivity or travel times. Induced seismicity generates a direct signal usually associated with the propagation of the pressure front.

The range of seismic methods — which can be deployed — includes surface and borehole active time-lapse seismic surveys with re-deployable or permanently mounted source and receiver arrays and passive monitoring, e.g. using any components of the wave field that originated from the seismic sources beyond our control. Many CO2 geosequestration sites are located near large sources of CO2 emission, such as populated areas with existing infrastructure. As such, the monitoring strategy must accommodate sharing the land (or ocean) with other users and have a minimal environmental impact. Furthermore, geosequestration is a form of waste disposal that must be cost-efficient. All these factors make CCS a leader in innovation, being an early adopter of such disruptive technologies as distributed fibre optic sensing and permanent reservoir monitoring. Small-scale demonstration projects focusing on the testing and development of CCS technologies play a critical role in this innovation.

This lecture is based on Australian CCS projects, such as the CO2CRC Otway Project and CSIRO In-situ Lab Project, which showcase the evolution of the seismic monitoring technology from conventional land 4D seismic to continuous or on-demand monitoring using permanent downhole and near-surface geophone and distributed acoustic sensing (DAS) arrays. We discuss how monitoring objectives can be achieved using various acquisition geometries, including land 4D, 4D vertical seismic profiling (VSP), and offset VSP, all of which can be implemented using conventional and permanently mounted seismic sources. Also covered is the automation of data acquisition and analysis, as well as passive data analysis.

Drinks and nibbles will be available from 5:30pm - 6:15pm. The talk will commence promptly at 6:15pm. ASEG would like to thank our sponsors for their continued support.

Speaker: Prof Victor Mocanu,

Registration:  ASEG WA Special Tech Night - Prof Victor Victor Mocanu Tickets, Wed, Mar 22, 2023 at 5:30 PM | Eventbrite

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

Date and time: Wed, Mar 22, 2023, 5:30 PM AWST


We demonstrate the effectiveness of using complementary geophysical and geological methods to better understand the structure and petroleum potential in a mature, late life producing oil field in the internal part of the Romanian Eastern Carpathians, in the so-named Tisza-Dacia block, an area in Central-Eastern Europe.

161 years ago exploration work indicated positive results and several wells were drilled. Crude oil extraction started as early as 1899 and continues until present, with several interruptions. Without serious advanced exploration activities and mainly based on interpretation of poor well cores, the extraction was a temptation despite the not-so-significant production.

Several wells reported basement at shallow depth between two major crustal faults and so the hydrocarbon prospective was considered as limited.

Some 15 y ago the new 2D seismic was of modest quality, so resistivity, gravity and magnetics plus MT data were added over geochemical sampling and geological re-mapping. This is an example of how a historic production could be boosted by integration of geophysical with non-geophysical methods so that the resulting geological model is modernly calibrated. The seismic data reprocessing by better velocity picking, statics and migration was based on a mixture of geodata. But the real original approach is represented by carefully looking into complex methodology with positive results in a mature field of over 100 y of production history.


Drink tokens and nibbles will be available from 5:30pm - 6pm. Technical presentation will start shortly after 6pm. ASEG would like to thank our sponsors for their continued support.
