Seismic attenuation, dispersion, and anisotropy in porous rocks: Mechanisms and Models
Boris Gurevich, Curtin University and CSIRO, Perth, Australia

Understanding and modeling of attenuation of elastic waves in fluid-saturated rocks is important for a range of geophysical technologies that utilize seismic, acoustic, or ultrasonic amplitudes. A major cause of elastic wave attenuation is viscous dissipation due to the flow of the pore fluid induced by the passing wave. Wave-induced fluid flow occurs as a passing wave creates local pressure gradients within the fluid phase and the resulting fluid flow is accompanied with internal friction until the pore pressure is equilibrated. The fluid flow can take place on various length scales: for example, from compliant fractures into the equant pores (so-called squirt flow), or between mesoscopic heterogeneities like fluid patches in partially saturated rocks. A common feature of these mechanisms is heterogeneity of the pore space, such as fractures, compliant grain contacts, or fluid patches. Using theoretical calculations and experimental data, we will explore how this heterogeneity affects attenuation, dispersion, and anisotropy of porous rocks. I will outline a consistent theoretical approach that quantifies these phenomena and discuss rigorous bounds for attenuation and dispersion.

Deadline for Joint ASEG-PESA Young Professionals Mentoring Program (Queensland)

Call for Expressions of Interest for 2018/2019

Launch event to be held on Tuesday November 27th!

The Queensland branches of ASEG and PESA are initiating a mentoring program to assist Young Professionals (YPs) in obtaining local support in their career development from experienced members.

This program aims to facilitate face-to-face mentoring sessions to establish a more interpersonal partnership through which industry insights, knowledge and experience are shared to foster the professional and personal development of mentees.

In addition, we will also be launching a local Young Professionals’ network, with ties to federally coordinated YP networks in sister societies throughout Australia. Such networks exist as special interest groups within their respective societies and can be adapted to serve the needs and interests of their members.

The local YP network and mentoring program will be launched at a special event to be held between 5:30 - 7:30 pm on Tuesday 27th November at a local Brisbane venue. We will start with a presentation about the local industry. Following this we will have a group discussion on the mentoring program and potential YP training opportunities, followed by networking with potential mentors in an informal setting with light refreshments provided.

Who can be a Mentor?

Mentors should have 10 or more years’ experience and be willing to commit to a 6-12 month program consisting of six mentoring sessions on a voluntary basis. Mentoring sessions are informally arranged by individual participants. Mentors must be a current member of either PESA or ASEG.

Who can be a Mentee?

Mentees should ideally have 1 to 10 years’ experience, and be willing to commit to a 6-12 month program consisting of six mentoring sessions. Mentees must be a current member of either PESA or ASEG. Unemployed or postgraduate student members are also welcome to apply. The program will be initially capped at 10 mentee/mentor pairs.

How much does it cost to participate?

At this point in time the program is free and fully sponsored by ASEG and PESA.

Registration

Please complete the relevant short survey by COB Friday 2nd November.

Seismic Full Waveform Inversion for Fundamental Scientific and Industrial Problems.

Seismic waveform inversion is a powerful method used to quantify the elastic property of the subsurface. Although the development of seismic waveform inversion started in the early 1980s and was applied to solve scientific problems, it became popular in industry only about 15 years ago. One of the key elements in the success of seismic waveform inversion has been the increase of the acquisition of long offset seismic data from 3 km in the early 1990s to more than 15 km today. Not only did long offset data provide refraction arrivals, but it also allowed recording of wide-angle reflections, including critical angles, providing unique information about the subsurface geology.

In this talk, I will elaborate on the early development of the seismic full waveform inversion (FWI) and its application to solve fundamental scientific problems. The first big success of FWI was its application to gas hydrate reflections, also known as bottom simulating reflection (BSR), which showed that the
BSRs are mainly due the presence of a small amount of free methane gas, not a large amount of hydrates stored above the BSR, and hence the total amount of methane stored in marine sediments should be much less than previously estimated. A second major success of FWI was its application to quantify the characteristics of the axial melt lens observed beneath ocean spreading centers. The seismic full waveform inversion results show that one can distinguish between pure melt and partially molten mush within a 50 m thick melt lens, allowing to link the melt delivery from the mantle with the hydrothermal circulation on the seafloor. The application of full waveform inversion to spreading center problems has become an important area of research.

Unlike in sedimentary environment, the seafloor in general scientific environment could be very rough and water depth could be deep, making it very difficult to use the conventional method of background velocity estimation. To address this issue, the surface seismic data could be downward continued to the seafloor, as if both streamer and sources were placed on the seafloor, similar to land geometry. This method allows to bring the refraction starting from zero offset to far offset, which is extremely useful for full waveform inversion of first arrivals. The downward continuation also allows to reduce the seafloor diffraction, increase the moveout of reflection arrivals, and enhance wide-angle reflections, all important for seismic full waveform inversion. The application of a combination of downward continuation and FWI has allowed to quantify gas anomalies in sedimentary basins and fluids at subduction fronts. The waveform inversion also has been used to monitor CO 2 sequestration.

I will explain the intricacy of FWI, based on the physics of waves, specifically the role of amplitudes and converted waves in addressing fundamental scientific problems. The presentation should interest professionals working in the oil and gas sectors, or crustal studies and global seismology.

Dorothy Hill Women in Earth Sciences Symposium

The School of Earth and Environmental Sciences (SEES) at The University of Queensland is proud to host the inaugural Dorothy Hill Women in Earth Sciences Symposium which will be held on Wednesday 15 and Thursday 16 November 2017 at The University of Queensland.

 

The Symposium celebrates the achievements of notable women in the Earth Sciences and is named after the late Dorothy Hill, who was the first woman Professor in Australia, the first woman to become a member of the Australian Academy of Sciences and its first President. 

 

Professor Dorothy Hill was a pioneer of research, a leader for women in science, a woman of action, and one of The University of Queensland’s (UQ) most outstanding graduates.  She was a well-known figure at the University from the time she was 18 years old and beginning her degree until she retired, aged in her seventies. By then she had become a world-renowned professor.  Throughout her career, she led by example and inspired women to pursue science and a university education. Through her numerous achievements, she helped to advance the place of women in academia.

 

This inspirational event will be a powerful two days of learning. Come and learn from, and network with, some of the world’s top female earth scientists.  Speakers include:
