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 Read More
The Valhall LoFS Project
The Valhall permanent seismic array (Life of Field Seismic; LoFS) has successfully provided easy access to high quality 4D images for the purpose of improving oil recovery. This article provides Read More
Mid Cretaceous Source Rock Enigma
Large-scale volcanism caused by a superplume in the mantle was possibly responsible for wide-spread deposition of excellent source rocks in Mid-Cretaceous times. Organic rich source rocks buried deep in sedimentary Read More
The Valhall Story
Renowned North Sea geologist Richard Hardman looks back at the 1975 discovery of the billion barrel Valhall Field. Perhaps the most surprising thing about the discovery of the Valhall field Read More
4D Geophysical Data
Building on ongoing IOR research efforts, StatoilHydro aims to be a leading company in quantitative integration of 4D data in reservoir modelling in order to meet challenges in the most Read More
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 Read More
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 Read More
New Insights Beneath the Salt
ION’s BasinSPANTM regional 2D programs feature surveys designed for the purpose of imaging the full crustal architecture. Their BrasilSPAN program is showing never before imaged sub-salt horizons and new stratigraphic Read More
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 Read More
Brazil’s Reserves will Last 50 Years!
Giant discoveries in the pre-salt play are expected to boost Brazil’s production to almost 6MMbopd within 10 years. According to Edison Lobo, Brazil’s Energy Minister, sufficient reserves have been found Read More
