Geoscience education and research at the University of Bergen
By R. MjeldeThis is the first article in an ongoing series on geoscience education in academic institutions in Europe and neighbouring countries. The series is part of an initiative in which recently nominated ‘EAGE Ambassadors’ have been invited to help develop stronger links and awareness among undergraduate and PhD students about the broad range of EAGE interests from oil and gas to near surface geoscience. In this article Prof Rolf Mjelde* describes the organization and educational programmes for geoscience students at the Department of Earth Science, University of Bergen, and also outlines some of the institution’s most significant research projects and achievements.

How BP sees world energy picture
2004 was a year of rising energy prices and growing concern in many parts of the world about the security of future supplies, according to the BP’s 2005 edition of its Statistical Review of World Energy. A summary and discussion of its main findings are presented below, followed by a critical comment from the Association for the Study of Peak Oil and Gas (ASPO).

An airborne EM survey of a landfill that leaked
By D. BeamishThe British Geological Survey continues to highlight the need for, and environmental assessment potential of, modern, multi-sensor airborne geophysical data in the UK. Here David Beamish,* head of airborne geophysics at the BGS, describes some results obtained from a detailed survey of a legacy landfill.

How educators in Europe see the university challenge
There appears to be a crisis looming in the education, recruitment, and training of geoscientists for the E&P industry and many other activities involving the use of geoscientific methods. It is the intention of the EAGE through First Break to highlight some of the issues involved with a view to coming up with realistic solutions which address the problem of attracting students, providing interesting courses at university level, and reversing the disturbing trend of declining numbers taking geoscience - and engineering - courses. To start what is intended to be a continuing discussion on key education, recruitment, and training issues, we asked some educators well known to the EAGE membership to provide us with their personal thoughts on the challenges ahead.

Regional time-depth conversion of the Natih E horizon in Northern Oman using seismic stacking velocities
Authors P.C.H. Veeken, J. Filbrandt and M. Al RawahyA method is presented for integrating stacking velocity data in the time-depth conversion of regional time horizons in North Oman (Fig. 1). The Natih E horizon has been chosen as the target for the depth conversion as it forms a well-defined seismic reflection in Northern Oman (Figs. 2 and 3). The Cretaceous Natih Formation is composed of a series of limestone beds, ranging in age from latest Albian to Early Turonian. Timeequivalent source rocks occur (Van Buchem et al., 1996) in addition to organic-rich sediments in older formations, making the hydrocarbon charge for the mapped traps less of a problem. Conventional well-based time-depth (TD) conversion methods have their limitations, especially when dealing with vast areas, irregular distribution of control points, and a complex subsidence history (local inversion tectonics; e.g. Veeken, and Van Moerkerken, in preparation). Most methods are only appropriate when enough well penetration is available to calibrate the data set. If too large an interpolation or extrapolation distance is given, then these methods become notoriously unreliable. In such cases, seismic stacking velocities may provide the only means to evaluate the subsurface structuration (Veeken, 2005). The velocity cube represents an excellent asset for detailed prospect evaluation (Schulz, 1999). Many essential reservoir attributes are based on seismic velocities (e.g. impedance contrasts) and therefore it is worthwhile expending some effort exploring all of its benefits.
