Low-frequency Seismic Noise: The Music of Oil?

Passive low-frequency seismic is an area of active research and development, and is rapidly being taken up as a new direct hydrocarbon indicator (DHI) technique for exploration. The interest in the method is high, in particular since Spectraseis AG, the leading provider of low-frequency geophysical solutions to the oil and gas industry won the World Oil Award for Best Exploration Technology in October 2007. However, despite the empirical evidence supporting the technique, the underlying physical mechanism has not yet been fully identified.

The Next Generation Subsurface Modelling

Modelling reservoirs using a 3D grid is a common tool for both the geologist and the reservoir engineer. As models increase in structural and stratigraphic complexity the process of creating these grids has become cumbersome. In many cases the results are not satisfactory to either the geologist or the engineer.
