GEO Tourism Africa

A Truly Magical Place

The Ngorongoro Conservation Area in Northern Tanzania is a World Heritage site renowned for its beauty and unique wildlife and one of the few places where active continental break-up and its attendant magmatism can be observed today.

Exploration Europe

Exploring the Icelandic Frontiers

Iceland is renowned for its hot springs, geysers and active volcanoes that erupt from time to time, not world-class oil and gas production – but could basins close to this sparsely populated North Atlantic island be concealing significant hydrocarbon potential?

GEO Media Africa

New Digital Africa Maps

New digital maps, based on ones originally produced by Africa specialist Ed Purdy, should shed new light on the exploration of the continent.

Q&A Worldwide

Do We Need Another Seismic Company?

New kid on the offshore seismic block, Dolphin Geophysical, started trading in 2010 and has been growing steadily ever since. But with a few notable exceptions, seismic companies seems to come and go with great rapidity, so does the industry need yet another? We ask Atle Jacobsen, Chief Executive Officer of Dolphin, to answer this question.

Ghana/Sierra Leone Lookalike Plays in Northern Brazil

Following the recent major discoveries in West Africa, a new focus has been placed on the conjugate margin in northern Brazil, where over the entire 2,200 km margin only 20 wells have been drilled in water depths greater than 500m. Using the analogy from equatorial African discoveries, it appears that the highest potential may be in the deep waters on the slope and continental rise of the Brazilian margin. ION’s Greater BrasilSPAN™ data is being used to identify and map new plays similar to those currently being drilled on the African margin.

Learning from the Past?

As this edition of GEO ExPro magazine bears out, some of the most exciting areas in the oil and gas industry at the moment are in Africa; and not the traditionally ‘oily’ places, like the Niger Delta, equatorial West Africa or the Libyan Desert, but previously disregarded regions like the West African transform margin, presalt Angola and the east African Rift Valley – the latter featuring on our dramatic front cover.

Technology Explained North America

Beyond Macondo

“The major difference between a thing that might go wrong and a thing that cannot possibly go wrong is that when a thing that cannot possibly go wrong goes wrong it usually turns out to be impossible to get at or repair.” <em>Douglas Adams, Mostly Harmless</em>

Harnessing Dr. Scott Tinker’s enthusiasm and boundless vivacity may not instantly solve the global energy equation; however he is delivering a clear directive on energy that we all can embrace.
