Prospects for activity levels in the UKCS
By A. KempWe present here edited notes and revealing, if somewhat pessimistic, illustrations on future projections of UK oil and gas E&P activity in the years to come from the presentation by Prof Alex Kemp, Professor of Petroleum Economy, Aberdeen University. The conclusion from the data presented was that the UK will in less than five years be facing a sharp decline in offshore activity caused to a large extent by factors beyond the control of a single country.

Automatic seismic prediction ahead of the tunnel boring machine
More LessAs the world's population grows, with rapid economic expansion, there is an increasing demand for better transport links to improve the mobility of goods and people. As a result more and more tunnels are being built. For example, at the turn of the year 1998/99 more than 200 kilometres of tunnel with a diameter over 1 m were under construction in Germany. About three-quarters of this kilometrage is built for road-or rail-based transportation systems. For economic and safety reasons an increasing portion of tunnels are nowadays drilled by tunnel boring machines (TBM's also called tunnelling machines), particularly in soft ground i.e. less consolidated sediments. For example, 11 TBM's have been employed to bore the 50.5 kilometre Eurotunnel between France and England which mainly passes through Lower Cretaceous chalk and clay. TBMs remove soil and rock from the tunnel face as the cutting wheel rotates and the machine pushes forward, In hard rock traditional drill-and blast still dominates over TBM, but in soft ground most tunnels today are bored by tunnelling machines.

Depth imaging and velocity calibration by 3D adaptive tomography
Authors A. Vesnaver, G. Böhm, G. Madrussani, G. Rossi and H. GranserReflection tomography is an effective technology for reconstructiong a macro-model of the Earth, i.e. its major velocity anomalies and reflectors, especially in complex 3D geological structures. After the pioneering papers of Gjoystdal & Ursin (1981) and Bishop et al. (1985), traveltime inversion of reflected and refracted arrivals has been used to improved static corrections and near-surface imaging. The authors of this article have processed a data set over important producing fields which was acquired by OMV in the Vienna Basin, between Vienna and the border with the Slovak Republic. The tectonic complexity of the area, with major faults and static problems, made this data set a severe test of the robustness of the algorithms they have developed.
