Semi-submersible vehicle for shallow coastal waters

Semi-submersible vehicles have hollow shaft angle sensors to maximise space

A new broadband solution takes to the water

A superior broadband marine seismic solution offers a new combination of leading equipment, unique acquisition techniques and patented de-ghosting and imaging technology to provide better subsurface images. Jo Firth reports

Hostile wells: the borehole seismic challenge

William Wills discusses some of the basic exploration challenges faced with characterising deep reservoirs in such a high risk, high cost environment, and the requirements of downhole seismic tools to overcome such issues

Presalt focus firmly on Brazil

Brazil's presalt area remains a focus for investment in South America. Sean Ottewell reports

The challenges of mapping small restricted sites

Carlo Peris and Tom Hiller describe an operation to perform bathymetric and topographic surveys to obtain accurate depth maps

Remote exploration: the changing world of satellite communications

In what is a highly data-intensive industry, ships once had to collect seismic and other exploration data and bring it back with them when the ship next docked in port. But, as the search for oil and gas moves into deeper waters, satellite technology is the only realistic option for communication. Simon Watts reports

Deeper insight into the subsurface

The rising speed and lowering cost of processing power means that generating a complete synthetic seismic data set is now affordable for individual companies and many times cheaper than an actual seismic survey

Innovative approach to delivering integrated seismic PRM

Stingray Geophysical Limited has adopted an innovative approach to providing integrated seismic permanent reservoir monitoring

Cost and safety drive cable developments

The harsh conditions that cables are exposed to in the offshore environment are making manufacturers focus on ever more durable solutions. Sean Ottewell reports

Integrated navigation and control system

Paul Newman provides an overview of Gator, the navigation and control software for ocean bottom cable surveys

Efficiency drives in a recovering market

After a period of major belt tightening in 2009 we find ourselves at mid-2010 with the marine seismic exploration market showing global activity increasing month-on-month. Neil Grosse reports

Streamer technology improves resolution of data

Keith Forward reports on how the resolution of seismic data is being improved by the use of velocity sensors alongside pressure sensors
