Synopsis top ↑

The global reserve of conventional fossil fuel is being depleted at an fantastic rate. The societal demand for abundant petroleum-based energy currencies drives the search for new sources of oil and natural gas. In many of the World's basins, the exploration for hydrocarbons has reached a mature stage. This is particularly true for shallower deposits (< 5000 m) of Tertiary and Mesozoic ages. Now alternative exploration strategies and even philosphies are required. The search for deep gas is rapidly gaining interest as a new exploration frontier. Deep-seated reservoirs have already been drilled successfully, such as the 9 km Lone Star Earnest Baden No. 1, in the Anadarko basin, U.S.A., or others in the Delaware, and Val Verde basins (see Rice), but in many petroleum provinces, deeper targets are only now becoming attractive. The first International Deep Gas Workshop was held in Hannover, May, 1990. Under the co-sponsorship of the German Federal Ministry for Research and Technology (BMFT) and the International Energy Agency (IEA), close to 200 delegates worldwide gathered to discuss the new frontier of deep gas. The definition of deep gas is purposefully vague, but in most parts of northern Europe this is understood to mean pre-Westphalian sources or accumulations. Although there was considerably delay in the publication of this volume, this collection of papers seeks to capture the spirit of the Hannover meeting, and to provide a basis of future activity.

Etliche erfolgreiche Bohrungen, wie die 9 km Lone Star Earnest Baden No.1 im Anadarko Becken, USA, oder andere in den Delaware- und Val-Verde-Becken (siehe Rice), wurden bereits in tiefgelegene Speicher niedergebracht, aber es gibt noch viele andere Kohlenwasserstoffprovinzen, in denen tiefere Targets nun an Attraktivität gewinnen. Der erste Internationale Tiefengas-Workshop fand im Mai 1990 in Hannover statt. Unter Mitverantwortlichkeit des deutschen Bundesministeriums für Forschung und Technologie (BMFT) und der International Energy Agency (IEA) kamen fast 200 Teilnehmer aus aller Welt zusammen, um die Herausforderungen des Tiefengases zu diskutieren. Die Definition von Tiefengas ist absichtlich unbestimmt, in den meisten Teilen Nordeuropas versteht man darunter aber präwestfale Quellen oder Akkumulationen. Trotz der beträchtlichen Verzögerung bei der Veröffentlichung dieses Bandes versucht diese Sammlung von Arbeiten den Geist des Workshops in Hannover widerzuspiegeln und eine Grundlage für zukünftige Aktivitäten zu schaffen.
