A little bit of history

The very first discovery on the Norwegian continental shelf was made in 1966 by Esso Exploration Norway Inc. Well 25/11-1 found small amounts oil in Lower Tertiary sandstones on the Utsira High. This was the second well offshore Norway.

I-Guazú: Great Water - Great Volcanism

Iguaçu Falls is one of the most spectacular natural sceneries in the world, caused by a wide-spread volcanic event in conjunction with continental rifting in the Early Cretaceous. This rifting episode has also meant a lot to the hydrocarbon potential on both sides of the Atlantic Ocean.

Using 4D Seismic

4D geophysics, in particular 4D seismic, has come of age. Repeated surveys with or without permanent receivers are now increasingly being used in monitoring production. This applies in particular to clastic reservoirs, meaning that one of the future challenges will be to make the technology also work for carbonates. Professor Dr. Martin Landrø now takes our questions.

Reality Hits Brazil’s Pre-Salt Play

Recent news of at least three dry wells and suspension of the Tupi extended well test illustrate some of the challenges facing the pre-salt play that Brazil's government has touted as having "no exploration risk." However, with the huge reserves already discovered, the frontier area remains a hot play.
