Structural Interpretation of Seismic Data and the Use of Well Data for Quality Control
More LessImprovements in seismic data quality, processing methods as well as hardware and software products during the last few years have led to more detailed and accurate seismic interpretations of offshore oil and gas fields. The use of seismic attribute maps and coherence technology has enabled the seismic interpreter to map faults down to, in some cases, 5 m displacement. When the interpretation is carried out in such detail, the geologist is faced with the problem of separating real features from seismic noise. In order to separate the noise from real structures, the geologist needs to incorporate all available information into an integrated interpretation approach.

Reflection of the Oligocene Flysch Folds at the Top Eocene Limestone Level
Authors E. Prenjasi and V. SiloMany known oil fields, as the Cakrani field (1), the Gorishti field (2), etc. discovered in the lonian zone of the Albanian thrust belt are related to the anticline structures of the Cretaceous-Eocene limestone overlain by flysch of the Oligocene age.

Palaeobathymetry from Seismic Interpretation and Structural Restoration
Authors T. Kjennerud, S. Fanavoli and G. GillmoreThe post rift phase of a rift basin is according to the model of McKenzie (1978) considered to be a phase of subsidence due to cooling of the lithosphere, following heat influx in the rift phase.

Deep Sedimentary and Crystalline Structures across he Outer Vøring Margin, N. Norway from OBSData
By R. MjeldeThe outer part of the mid-Norwegian margin, by many considered to have a high hydrocarbon potential, is difficult to map by use of multichannel reflection seismics due to the presence of flood-basalts and intrusions of sills at intermediate sedimentary levels.

FEModelling of the North German Basin - Considerations on Choosing Boundary Conditions
By K. FischerIn the Late Carboniferous (Namurian to Westphalian) the Variscan Foreland Basin of Central and Western Europe was formed north of the Variscan deformation front and extended 800 km parallel to the deformation front (Figure 1).

Northern Part of the Danube Basin, Slovakia - Polyhistoric, Composite Basin and its Hydrocarbon Prospectivity
Authors I. Hrusecký, A. Macko, D. Kúsik and P. KubesThe Danube Basin is a northwestern peripheral basin of the Pannonian Basin complex. This contribution is aimed at large central part of the basin on Slovak territory.

Ordovician - Early Devonian Sequence Stratigraphy and Evolution of the Timan Pechora Basin
Authors N. V. Taninskaya, V. G. Kots and K. ViskunovaThe Ordovician-Silurian-Lower Devonian deposits are one of the most prospective objects for oil and gas searches in the Timan-Pechora oil-gas-bearing province. They are presented- by carbonate rocks and occur at the depth of 3-6 km. More than 3D oil-fields are discovered in these deposits. Here the purpose is to predict reservoirs and seals in this carbonate complex.

Diapirizm, Mud Volcanizm and Folding in the Sedimentary Basins of Northern Peritethys
Authors A. I. Konyukhov, B. A. Solokov and N. S. YandarbievPhenomena of folding, diapirizm and mud volcanizm are well known in most of sedimentary basins of Northern Peritethys, especially in the Crimea and Caucasus regions, where Maykop Formation (Upper Oligocene - Lower Miocene) is wide spread.

East Slovakian Neogene Basin, Slovakia - Preliminary Results of a Study on Hydrocarbon Potential
Authors I. Hrusecký, J. Janocko, P. Kubes and D. KúsikThe hydrocarbon potential assessment of the East Slovakian Neogene Basin and eastem parts of the Central Carpathian Paleogene Basin and Outer Flysch Zone in Slovakia is the subject of a study that will last up to September 2000. The study is based on a play concept analysis using a multidisciplinary approach.

Paleothermic Conditions as a Factor of Petroleum Presence
By A. IvanovaPaleothermic conditions are a most responsible factor for the generation, accumulation and preservation of hydrocarbons. These conditions determine a thermal maturity of organic matter and its hearing deposits.

Oil Migration in Normal Versus High Pressure Regimes, Halten Vest and Haltenbanken, Nocs, Norway
More LessThe occurrence and geochemistry of petroleum inclusions in combination with fluid hydrocarbon reservoir samples and reservoir core extracts (Fig.1), is currently becoming an important tool, not only for detailed reservoir characterization, but also for documenting and timing large scale basinal movement of petroleum fluids into, within and out of reservoirs.

Tectonic and Palaeogeomorphologic Criteria for the Prognosis of Large Fields and Oil/Gas Accumulation Zones
Authors T. Prigarina, B. Kabyshev and O. SamarskaAs a result of thorough research carried out in the Dnieper-Donets Basin (DDB) and generalizing on a number of other oil/gas-bearing basins (the Volga-Urals, Western Siberia, Anadarko and others), there has been made an analysis of how such geological characteristics as sedimentation rate, thickness of deposits, depth of productive sequences; basement surface and Moho boundaries, extent of washout of deposits at hiatuses, presence of deep faults as well as the paleoparameters of hydrocarbon (HC) traps affect the size of oil/gas fields.
