Exploration and Beyond
Exploration and beyond is the philosophy behind WGP, a small independent geophysical company dedicated to developing solutions and services towards the next generation of energy supplies. In these days of…
Marine Seismic Sources Part IV
The 1956 documentary The Silent World by Jacques-Yves Cousteau wowed audiences with its vibrant depiction of aquatic life. But the Silent World is far from silent. Sound is signal or…
Depth Imaging – Seeing the Invisible
An analogy with bat technology makes it easier to understand seismic imaging of the subsurface. However, a bat’s sounds transverse a homogenous medium, while seismic waves in the earth are…
Shooting Seismic Does not Kill Fish
“Sound waves from seismic data acquisition resulted in increased catches for some species and smaller catches for others.” To me, that sounds a bit inconclusive, but it is still the…
Lessons to be Learnt
So, the Macondo well has finally stopped leaking and should be permanently sealed by the end of September, nearly five months since it first suffered a major blow-out. This has…
Ken Glennie – A Petroleum Pioneer
Ken Glennie, Honorary Professor of Geology at Aberdeen University and renowned author of three books, several co-edited publications and over 50 single-author and co-authored papers, has led the sort of…
Source Rock Subcropping in the Baffin Bay
Seabed samples from the Baffin Bay document an active hydrocarbon system offshore northwest Greenland. The northwest Greenland shelf is a frontier petroleum province in the arctic Baffin Bay. Limited seismic…
Linking seismic response to geomechanics
This article discusses the linkage between 4D seismic responses and geomechanics. Exploitation of this relationship has helped reduce development costs and maximize recovery from the compacting Valhall reservoir. The 4D…
Marine CSEM – what’s the future like?
Offshore Electromagnetic surveying, CSEM, was commercialized in 2002 as a new exploration technology for finding hydrocarbons. Following some seven years of trial and failure, we have asked one of the…
Reservoir Monitoring Technology
Permanent seismic monitoring is an emerging market with significant potential. Who are the major players and what has been done to validate the Optowave technology? This article has been designed…
Measuring Seismic with Light
Fibre optic sensing technology offers the potential for a cost-effective, reliable reservoir monitoring system as an alternative to seismic systems based on electronics. Interested in learning about fibre optic seismic…
