Country Profile Africa

Senegal Revisited.

Jane Whaley
In 2010 we reported that after over 50 years of exploration, Senegal had only delivered a number of small fields and produced 11 Bcf of gas, but was still waiting for the big discovery which would help fuel the country’s growing economy. We asked the question - does the prize lie in the deepwaters? In 'Senegal Revisited' we look again at this exciting country, at a time when answers to some of those questions may be about to be made.

Hot Spot North America

Eagle Ford Shale

Thomas Smith
What started as a major shale gas play, the Eagle Ford Shale could be the sixth largest U.S. oilfield ever discovered and the largest in forty years.

Lessons to be Learnt

Jane Whaley - Editor in Chief
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 been confirmed as the world’s worst ever oil spill, with nearly five million barrels of oil having poured into waters of the Gulf of Mexico. Thousands of birds and sea life have been killed or badly injured and the economy of the adjacent coast, very dependent on the Gulf, has taken a serious knocking.

Southern Permian Basin Atlas Unveiled

Jane Whaley
More than five years in the making, the recently published Southern Permian Basin Atlas is an excellent example of international co-operation and promises to prove of invaluable help to companies exploring for hydrocarbons in Europe.

Depth Imaging – Seeing the Invisible

Vetle Vinje, CGGVeritas
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 propagated through a highly complex elastic medium, creating a much more complicated problem for seismic depth imaging technology.

Exploration Australasia

Carnarvon Basin

Barrett Cameron, Fugro
Continuing Exploration Success with Eendracht 3D. Multiple exploration companies united to prefund Fugro’s largest non-exclusive 3D seismic survey in the Carnarvon Basin. The Cretaceous Barrow Group highs and Triassic Mungaroo tilted fault blocks identified in the Fast Track Cube have been the highlight of initial investigations into the dataset.

Giant Fields Middle East

The King of Giant Fields

Rasoul Sorkhabi, Ph.D.
Since the petroleum industry began in the mid-nineteenth century, numerous oil fields have been discovered and over 70,000 oil fields are still in use. Nonetheless, not all fields were created equally.
