Article
This study aims to assess the ability of shallow distributed acoustic sensing (DAS) to serve as a cost-effective seismic sensor array for permanent monitoring applications. To this end, as part of the CO2CRC seismic monitoring program, a fibre-optic DAS array was deployed alongside a permanently buried geophone array at the Otway Project site (Vict...

Surface waves removal method, basted on RTM approach, superior to conventional methods used in common practice. Program is designed to be able to remove surface waves or to extract them (option PASS) for further analysis, free of any other seismic energy, as well as, significant level of random noise attenuation.

In this paper, we are proposing a new methodology of 2D seismic acquisition and processing that aims to improve imaging of complex 3D geological environments. The method requires a simultaneous acquisition along two parallel receiver lines. The adapted processing highlights locations of the reflectors that are out of vertical plane by filtering the...

Full-text available
Seismic imaging techniques often require an input velocity model. Velocity analysis is one of the most critical stages in seismic data processing. Standard ways to find the velocity model from seismic data in the time domain are constant velocity stack and semblance velocity analysis that may be time consuming and labor intensive. Oriented/velocity...
Conference Paper
A permanent geophone array along with a fibre optic distributed acoustic sensing (DAS) array were deployed at the CO2CRC Otway Project site in order to conduct seismic monitoring of a CO2 plume during a small-scale injection test. This study aims to assess the ability for a permanent geophone array to overcome issues related to different acquisitio...
Article
SUMMARY A 3D seismic survey was designed, acquired and processed by HiSeis Pty. Ltd. in 2010 at the Kevitsa NiCu-PGE deposit. The objectives of the survey were the definition of sub-vertical structures (knowledge of which could assist in the design and characterization of the slopes of the proposed open pit), and mapping out the general structural...
Research
The application of seismic methods for mineral exploration is driven by the need to explore at deeper depths and under cover, where other methods lack resolution or depth of penetration. However, one of the drawbacks of seismic in its current implementation in hard rock environments is the costs involved in acquisition. For that purpose I will be d...
Article
Neves–Corvo is one of the biggest mining districts on the Portuguese side of the Iberian Pyrite Belt hosting six different lower Carboniferous copper, zinc, lead and tin orebodies including Lombador, Neves, Graça, Corvo, Zambujal, and Semblana. During the past 50 years, geological, geochemical, and geophysical methods were utilized in the explorati...

Novel approach of improving the Signal to Noise Ratio, where signal could be multiple times improved on the unstacked CMP gather, compared to classical CMP stacking procedure. Consequently, pre-stack quantitative analysis becomes possible on the reflection seismic with extremely poor SNR.
Conference Paper
Based on physical property measurements of core samples and the often observed difference in elastic properties from these there should be a significant difference in seismic amplitude between mineralisation and the surrounding host rocks. These results indicate that relative amplitude preservation processing may be of importance in the use of seis...
Article
A method for rapid generation of complex 3D geological models is presented. The method utilizes scaled physical models which are built out of simple materials that provide sufficient density contrast. The model is CAT scanned, assembled into 3D and elastic properties are assigned to each node. Subsequent post and pre-stack numerical simulations all...
Experiment Findings

Novel fast and efficient approach in multiple waves suppression, far more superior to F-K or Tau-Pi method, where energy of multiples at close offset is completely removed without harming primaries.
Article
The Naylor-1 monitoring completion, a unique and innovative instrumentation package, was designed and fabricated in FY 2007 at Berkeley Laboratory. Tom Daley, Barry Freifeld and Duo Wang (all from Berkeley Lab) were on site at the Otway Project between September 26 and October 14, 2007, working with CO2CRC and their subcontractors, AGR Asia Pacific...
