Unconventional (Tight) Oil & Gas Growth

In 2012 Australia ranked as the world’s 4th largest exporter of LNG.

Discoveries are continuing to be made in Western Australia, new basins and sub-basins are being found by methodical explorers and delineated onshore, and coal seam gas finds are being readied for production in Eastern Australia. Australia’s gas production is set to increase.


Whereas some markets are becoming saturated, there are fresh opportunities in Australia for those willing to have a go. Fracture stimulation is only just being recognised as the tool to unlock the potential of shale and tight plays.


Continually expanding infrastructure is linking new discoveries to markets and to export facilities. New LNG terminals are being constructed on the East and West coast to feed the growing appetite for clean energy in Asia.


With LNG capacity under construction, Australia is expected to reach an overall second spot after Qatar in 2014 and is projected to vie for the world’s top spot by 2017 – 2025.


In addition to new basins, production from existing basins has been growing since the 60s. The first phase, largely mapped for structural plays is being extended to stratigraphic plays, and now the push is on for basin-centered shale and tight gas exploration.


New seismic methods and data are the primary tool for exploration of these new plays. Seismic is among the tools being used not only in new exploration, but is also playing an increasingly important role in successful optimisation, orientation and layout of (horizontal) appraisal and development wells. Full azimuth seismic is providing improved imaging and valuable property prediction. “Fracturability” or brittleness, regional and local stress field, stress anisotropy and azimuthal anisotropy are among the properties geophysicists are attempting to determine from high quality seismic. AusGeos is on the front line by reprocessing existing 3D datasets to anisotropy using specialised anisotropic processing. These processes are yielding impressive results (see our Downloads page).


State-of-the-art cable-less acquisition and processing is being used for both structural and stratigraphic delineation and for rock and reservoir property identification and prediction. Amplitude, semblance, dip steering and proportional slicing to map stratigraphic architecture, and azimuthal velocity to help predict stress and fracture zones for well placement, hazard avoidance, and for optimised Geosteering, as well as Geology-driven processing and 5D Interpolation are the new tools of the trade.

We plan to undertake further studies geared to our clients requirements.


AusGeos Anisotropic Processing of existing data
We have developed Anisotropic processing of existing data. If existing 3D seismic land data contain sufficient azimuth information our processing gives azimuthal information for a fraction of the cost of a new survey. Not only that, it can be ready to use in months not years. Reprocessing of existing surveys is a hugely effective start relative to new acquisition. Our processing house handles 2D, 3D land and marine data at lower cost and includes the standard requirement of 5D interpolation, amplitude and azimuth preservation.


RPMTM New approach for speed, better imaging and shallow section imaging for Coal Bed plays
We offer Equivalent Offset Migration as an alternative to conventional Kirchhoff. When provided within our RPMTM processing flow we see more accurate velocities, faster results, imaging up to ridiculously shallow depths and often lower costs. Of course if conventional Kirchhoff migration is required we can provide that as standard, and if required provide the EOM result as well. We are the only company providing both Kirchhoff and EOM migrations.


If you need shallow imaging for Coalbed exploration AusGeos’ RPMTM technology ought to be your first call.


Extended Elastic Impedance Inversion (EEI)
A powerful formulation for AVO analysis allows good quality data to be inverted to lithology and fluids. Extended Elastic Impedance can be used to supplement standard AVO work as required by the client.


Seismic survey design
Good seismic survey design (for the correct data density, offset distribution and range, full azimuth distribution, near surface, amplitude and azimuth preservation) is essential to achieve your exploration objectives and optimise your success. Our geophysicists can help you achieve your goals using their extensive experience.


Our team of geologists and geophysicists has on average 30 years’ experience in all aspects of interpretation of reflection Acoustic Impedance data (Seismic), Core analysis, Palynology, Geosteering, Attribute generation, Fault interpretation and Fault seal. Their experience has been applied to conventional reservoir exploration, unconventional reservoirs, and Carbon Capture and Sequestration projects. Whether you need help with permit applications, environmental regulations, mapping, data design, tenders or selection of contractors, acquisition, bird-dog, data QC, processing, interpretation, or microseismic, Ausgeos can help. By calling on our alliances we will give you access to some of the top service providers in Australia.


Microseismic Monitoring
Microseismic monitoring provides insight into fracture behaviour in Hydraulic Fracture Stimulations. AusGeos have teamed up with esg Solutions to provide microseismic monitoring services in Petroleum and CO2 applications. Downhole, surface or hybrid microseismic monitoring arrays help map fracture operations in real time, image Vertical Breakout and steam (and gas) movement, monitor caprock and well casing integrity, optimize injection strategies and staging, calculate Stimulated Reservoir Volumes, calibrate reservoir models and gain insight into frac effectiveness and reservoir characteristics. Such information has proved very effective in international settings and is now available in Australia.


If you are thinking about exploring in Australia – and remember, Australia is in the top third investment climate rank in the world – AusGeos teams have the right experience to help you.
