This is not only relevant for the detection of structural and stratigraphic features in controlled-source seismic data, but developed applications also have implications for data

Geology & Geophysics analysis in felds such as earthquake seismol- ogy, biomedicine, telecommunications, and remote sensing.

These combined projects should produce novel statistical signal processing tools for high-resolution imaging of small-scale struc- tures, leading to an increased confdence in the interpretation of current and new exploration prospects.

As the oil and gas industry has developed, so have its requirements on information quality and detail that can be extracted from the vast data collected by seismic surveys.

The output from this project, some of which is already being used by the sponsors, will result in processing software that can be applied on a range of datasets, including legacy data, new 3D seismic and repeat 4D surveys for exploration, appraisal and exploitation purposes.

As such, it may contribute to the discovery of new satellite felds, as well as enabling the progress of oil recovery from mature felds to be tracked.

Mirko van der Baan is the principal investigator of the

Blind Identifcation of Seismic

Signals JIP, and the Microseis- mic Industry Consortium, a collaborative venture with the

University of Calgary, dedi- cated to research in microseismicity. He is also a co-founder of the Centre of Integrated Petro- leum Engineering and Geosciences, a joint initiative of several departments at the Univer- sity of Leeds, UK, to foster and promote multi- disciplinary petroleum-related research and teaching.

Colin Sanderson has been with ITF since its formation in 1999. During this time, as a senior technology analyst, he has collaborated with researchers, technology developers, and industry domain specialists across a wide range of technology areas within the oil and gas industry. Recently, he has concentrated on subsurface activities.
