Seismic power source ups geohazard survey efficiency

Speed and efficiency are crucial when seismic survey operations take place inside the Arctic Circle

Eyes on the Arctic as race to find undiscovered energy intensifies

The Arctic promises much in terms of energy resources, but huge technical, economic, environmental and social challenges will have to be overcome if the region is to be exploited successfully

Cable protection is stronger, lighter and more versatile

With environmental issues and energy saving being hot topics in our current climate, you would not think that a cable fairing would be something that would spring to mind in either of those categories. Alan Cooper reports

Measurement of sound velocity and what sensor to use

There are currently two methods of obtaining sound speed in the oceans: calculating sound velocity from other physical parameters and measuring sound velocity directly

Time lapse seismic proves worth as a tool to boost field output

If one is looking for clear evidence that 4D (time lapse) seismic is worth its weight in gold as a tool to boost field output, they one need look no further than the Gullfaks field in the Norwegian sector of the North Sea

Measuring ocean currents for efficient seismic surveys

The demand for oil and gas drives exploration and production in to more and more complex environments. Grant Jennings and William Kikendall report

CSEM companies cut fleet sizes as market conditions deteriorate

Two late 2008 headlines indicate that all is not well with the world of controlled source electromagnetic resonance, at least in commercial term
