Session 03 #Seismic_survey

Oil and gas explorers use seismic surveys to produce detailed images of the various rock types and their location beneath the Earth's surface and they use this information to determine the location and size of oil and gas reservoirs.

Seismic processing requires powerful computers,sophisticated software and specialised skills.
Once the seismic has been processed, it must be interpreted by geophysicists. The results will be compared with other data (such as rock samples, regional well/drilling results and known geology) to enhance the accuracy of the interpretation. This often produces detailed understanding of geology to depths of more than 10km.


Seismic information is used to accurately plan locations for wells, reducing the need for further exploration and minimising environmental impact.

Contrary to the claims of some environmental groups, seismic surveying is a very well-understood science and a very safe industry practice.

More than four decades of seismic surveying and numerous research projects have shown no evidence that offshore seismic surveys harm marine animal populations or ecosystems.

The responsible precautions taken by industry mean the effects of man-made noises, such as seismic surveys, on marine mammals are insignificant. For example, whale populations can be found all along Australia's coastlines and seismic operators employ extensive precautions to minimise any disturbances to these animals.

Whale populations in Australia continue to thrive — humpback whale populations are increasing at close to their biological maximum, more than 10 per cent a year.

There is much more offshore oil and gas activity on Australia's west coast than on its east coast, but the rates of humpback population increase are almost identical. There is no evidence that seismic surveys off Western Australia have harmed Australia's humpback whale populations.
