Imaging past depositional environments of the North West Shelf of Australia: lessons from 3D seismic data
- Publication: Imaging past depositional environments of the North West Shelf of Australia: lessons from 3D seismic data
- Authors: Victorien Paumard, Julien Bourget, Simon Lang, Tom Wilson, Rosine Riera, Anthony Gartrell, Boyan K. Vakarelov, Mick O’Leary, Annette D. George
- Date Published: September 2019
Abstract:
Seismic surveys over the North West Shelf (NWS) of Australia have generated one of the largest 3D seismic data libraries worldwide with a coverage of ~325,000 km2 of mediumto high-quality data. A major challenge now is using the best tools and tech...
3D VERTICAL SEISMIC PROFILING ACQUIRED USING FIBREOPTIC SENSING DAS – RESULTS FROM THE CO2CRC OTWAY PROJECT
- Publication: Australasian Exploration Geoscience Conference 2018
- Authors: Julia Correa, Barry Freifeld, Michelle Robertson, Roman Pevzner, Andrej Bona, Dmitry Popik, Konstantin Tertyshnikov, Thomas Daley
- Date Published: February 2018
Abstract:
Distributed Acoustic Sensing (DAS) is an optical interferometric method for acquisition of acoustic and seismic signals. It uses laser pulses that travel along the length of a fibre-optic cable and backscatter as they encounter small inconsistencies ...
Portable X-ray diffraction for unconventional and conventional petroleum exploration
- Publication: Australasian Exploration Geoscience Conference 2018
- Authors: Dane Burkett
- Date Published: February 2018
Abstract:
X-ray diffraction (XRD) is a well-established technique in the earth sciences as it can be used to identify and quantify minerals and is particularly useful for fine-grained sedimentary rocks. Due to the capital cost, environmental requirements and s...
Reservoir Modelling, Structural History and Volumetrics of the Jerboa Area, Eyre Sub-Basin
- Publication: Australasian Exploration Geoscience Conference 2018
- Authors: Jordan McGlew, Prof. Gregory Smith
- Date Published: February 2018
Abstract:
The Eyre Sub-basin is situated in the Bight Basin in the Southern Margin. It covers an area of approximately 8,000km2. It is one of several half-graben in the Bight Basin that formed during the initial rifting between Australia and Antarctica. Sedime...
Ranking DHI attributes for effective prospect risk assessment applied to the Otway Basin, Australia
- Publication: Australasian Exploration Geoscience Conference 2018
- Authors: Sebastian Nixon, Tony Hallam, Andrew Constantine
- Date Published: February 2018
Abstract:
The first evidence of seismic brightening linked with gas charged reservoirs was recognised by Shell in the very late 1960s in the Gulf of Mexico. Since that time the terms bright spots, flat spots, amplitude versus offset (AVO) anomalies or gas anom...
Solid substitution: theory versus experiment
- Publication: Australasian Exploration Geoscience Conference 2018
- Authors: Yongyang Sun, Maxim Lebedev, Vassili Mikhaltsevitch, Stanislav Glubokovskikh, Stefan Iglauer, Boris Gurevich
- Date Published: February 2018
Abstract:
Gassmann fluid substitution is widely used in geophysical practice. In the last few years, the topic of fluid/solid substitution has emerged, where the substances filling the pore space can be solids, fluids, or visco-elastic materials, such as heavy...
Least Square Q-Kirchhoff Migration: Implementation and Application
- Publication: Australasian Exploration Geoscience Conference 2018
- Authors: Xiaodong Wu, Yi Xie, Joe Zhou, Dechun Lin, Yu Wang
- Date Published: February 2018
Abstract:
Absorption effects caused by the anelastic nature of the earth lead to the attenuation of amplitude and distortion of phase of seismic waves. The so-called quality factor “Q” accounting for this absorption effect has to be included for correct im...
Geochemistry of storing CO2 and NOx in the deep Precipice Sandstone
- Publication: Australasian Exploration Geoscience Conference 2018
- Authors: J. K. Pearce, D. Kirste, G.K.W. Dawson, I. Altaf, S.D. Golding, J. Undershultz
- Date Published: February 2018
Abstract:
The Precipice Sandstone in the Surat Basin is being appraised for CO2 geological storage owing to its high porosity and permeability and expected high injectivity. Generally it is quartz rich with variable kaolinite, however detailed characterisation...
