Seismic reservoir interpretation of deep Permian carbonates and sandstones (NW German gas province)
By M. BudnyReservoir descriptions of deep Permian gas fields in the onshore North-west German Basin have concentrated in the past on well-data correlation to derive geological reservoir models, The contribution of seismic data was focused on structural mapping of faults and seismic markers near the reservoirs, a difficult task in many cases due to structural complexity, strong velocity variations and salt domes.

An experience in seismic amplitude processing
Authors A. Mazzotti and S. MirriThe source in seismic reflection surveys generates elastic waves in the ground. These may be considered as a transient disturbance which radiates outwards into the earth. Along the propagation path, inhomogeneous, anisotropic and imperfectly elastic media are encountered, and hence the amplitude of the disturbance will decay in a complicated manner as it propagates, dependent on the charactéristics of the media through which it passes. The amplitude of the reflected signal which we attribute to a certain horizon cannot therefore be directly related to the contrast in velocities and densities encountered by the seismic wavelet at the reflector, because many other perturbing factors exist.
