3D Contrast Property Mapping

Robert van Eykenhof and Etienne Wildeboer Schut, Fugro-Jason, and Vincent Aubin,
One of the major challenges in understanding the nature of the subsurface is to accurately depict geology when data are sparse. By combining well logs and seismic data, seismic inversion can be used to visualize subsurface geostructures in a realistic form.

GEO History Europe

The First UK Giant Oil Field

Jane Whaley
The giant Forties Field was discovered in 1970, only the second oil field to be found in the UK North Sea. Originally predicted to run dry by the early 1990, it has now produced 2.64 billion barrels – and is expected to continue for another 20 years.

GEO Tourism Europe

The Dinosaur Coast

Halfdan Carstens
The steep, towering cliffs along the Yorkshire Coast of northern England have become a favoured field excursion destiny for petroleum geology students. Excellent analogues to the Middle Jurassic Brent reservoirs in the North Sea make a perfect excuse for students who need practical exercises in sedimentology.

Exploration Europe

Jurassic Targets

Lars S. Eikum, Geological Advisor - Fugro
While the first deep water wells in the Norwegian Sea failed to reach the Jurassic, significant data improvements may now make it possible to delineate Jurassic targets in deep grabens and structural highs.

Technology Explained Asia

Drilling Uphill

Paul Wood
In Brunei, Shell has an ongoing programme drilling into the reservoir from below. Drilling, completing and producing an upside-down well, however, poses a number of interesting questions.

Industry Issues Europe

Is the North Sea down and out for the count?

Jane Whaley
The third and final Geocontroversy debate at the 7th Petroleum Geology Conference last year centred on the future of one of the most mature hydrocarbon areas in the world, as delegates discussed the motion: ‘Is exploration in the North Sea finished?’

Agreement in the Barents Sea

Halfdan Carstens
“This is a historic day. We have reached a breakthrough in the most important outstanding issue between Norway and the Russian Federation,” said Prime Minister Jens Stoltenberg prior to the signing of an agreement between the Norwegian and the Russian negotiating delegations on the bilateral maritime delimitation in the Barents Sea and the Arctic Ocean.

Exploration Europe

Faroe Islands: Success Near

Jane Whaley
For years the Faroe Islands have had to look on while their larger neighbours in north-west Europe have extracted untold riches in hydrocarbons from offshore acreage. Has their turn finally come?

Country Profile Africa

An Underexplored Salt Province

Jane Whaley
A thirty year independence struggle with Ethiopia means that the natural resources of Eritrea remain largely untapped, but there is ample evidence that this now peaceful country is highly prospective for oil and gas.
