A geothermal power plant projected in Unterhaching, south of Munich/Germany, will generate 3.36 MW of electrical power. Two boreholes (doublet) have developed the karstified Malm at a depth of approx. 3000 m. Available seismic profiles were reprocessed with the aim of interpreting the facies and thus the degree of karstification within the Malm. The most prospective areas are, beside fault zone...

This paper details a methodology for taking into account seismic information into 3D high resolution stochastic simulations of lithofacies. The simulation is based on a non stationary truncated gaussian approach. Within this frame, a 3D matrix of facies proportion is built. It is estimated from both well and seismic-derived proportions. Thus the seismic attributes are previously turned into sof...

To first order, seismic data provides the geologist and the geophysicist with information on the geometrical relationships between subsurface lithologic boundaries. Generally, this spatial information is used to construct conceptual geologic and process models with which to explain the origins of stratigraphic features. From such models we infer lithologic content. Various methods (e.g. AVO, Co...

Most current seismic methods to seismically characterize fractures in tight reservoirs depend on a few anisotropic wave propagation signatures that can arise from aligned fractures. While seismic anisotropy can be a powerful fracture diagnostic, a number of situations can lessen its usefulness or introduce interpretation ambiguities. Fortunately, laboratory and theoretical work in rock physics ...

Reservoir heterogeneities exist at several length scales. Reservoir properties will depend on the scale that we are analysing on the reservoir (from core to grid block). Facies are normally identified in cores and classified based on microscopic and small scale features such as lithology, grain size, texture, sedimentary structure, colour and fossil content. However, facies information is only ...

Abstract One of the primary purposes seismic stratigraphy is to evaluate components layer relationships within a depositional chronology. Prestack images contain wealth information, such as variations in offset and azimuth event, naturally produce higher-resolution facies analysis results than poststack data. However, prestack data usually suffer from potential unreliability issues due low sign...

High-resolution seismic data and sediment cores reveal the late Holocene subsurface stratigraphy of the broad Tappan Zee– Piermont region of the Hudson River Estuary. We identify a series of distinct, extensive horizons beneath the marginal flats, channel banks, and main channel in this area. Physical properties and lithology from sediment cores suggest that these horizons are surfaces of erosi...

A detailed, high-resolution stratigraphic analysis of the Mediterranean Outflow contourite system at the continental slope of the Gulf of Cadiz has been carried out through the correlation between a dense network of seismic reflection profiles (sparker, airgun, 3.75 kHz and parametric echosounder — TOPAS), Calypso giant piston and standard gravity cores. From such correlation we determine a sta...
