Exploration of Lower Cretaceous sands in the Leland Area, Alberta, using seismically derived rock properties
Authors C.C. Dumitrescu, F. Mayer and R. CouzensAfter describing the processing sequence necessary, Carmen C. Dumitrescu, Fred Mayer and Rodney Couzens present a study based on Canadian data in improving the resolution of different seismic attributes obtained from deterministic inversion using neural network analysis.

Value of illumination-consistent modelling in time-lapse seismic analysis
Authors A. Drottning, M. Branston and I. LecomteÅsmund Drottning and Mike Branston of NORSAR together with Isabelle Lecomte of NORSAR R&D Seismic Modelling discuss the importance of including overburden effects in time-lapse analysis and demonstrate a computationally efficient method of including illumination characteristics in a seismic time-lapse modelling workflow from the Norne field, Offshore Norway.

Reducing the exploration cycle with effective onboard processing
Authors T. Manning, M. Dvorak, T. Allen, A. Poole, D. Fear, G. Stock and H. AbdulgialilTed Manning, Martin Dvorak, Tony Allen, Alan Poole, Dawn Fear, Graeme Stock and Hussein Abdulgialil outline how onboard processing based on a combination of rigorous pre-planning, powerful equipment, and operational flexibility can effectively serve even the largest marine seismic surveys and help to reduce exploration cycle times.

Using automatically generated 3D rose diagrams for correlation of seismic fracture lineaments with similar lineaments from attributes and well log data
Authors S. Chopra, K.J. Marfurt and H.T. MaiDetection and characterization of fractures in reservoirs is of great importance for maximizing hydrocarbon productivity and recovery efficiency. Coherence and curvature are two seismic attributes that have shown promise in identifying groups of closely spaced fractures or interconnected fracture networks. Curvature attributes, in particular, exhibit detailed patterns from fracture networks. We report the automated generation of rose diagrams from seismic attributes throughout the 3D volume which can be visually correlated to the lineaments seen on different seismic attributes like coherence and quantitatively correlated to the rose diagrams available from image logs. Since these rose diagrams are generated at regular grid points on each time slice, they are essentially 3D rose diagrams. Visualization of these volumetric 3D rose diagrams with other discontinuity attributes lends confidence to the interpretation of fracture lineaments.

GeoStreamer – increasing the signal-to-noise ratio using a dual-sensor towed streamer
Authors R. Tenghamn and P.E. DhelieSeismic exploration today and in the future will require looking for deeper reservoirs, under more complex overburden and within increasingly complex stratigraphic traps. To be able to image these reservoirs well, the bandwidth of the seismic data must be extended at both low and high frequencies and an improvement in signal-to-noise ratio is also required. A new dual-sensor streamer was launched in 2007 and has since been deployed in 2D mode in several basins worldwide. The first 3D dual-sensor streamer survey at the DeSoto Canyon in the Gulf of Mexico was completed in early 2009. The combined dual-sensor data from the GeoStreamer are superior to the data recorded using a conventional towed streamer in two ways. Elimination of receiver ghosts provides a much clearer, higher resolution image and, due to the ability to tow deeper, the stronger low reflection signal frequencies and the weaker swell noise result in greater penetration. A gain of 10−15 dB in signal-to-noise ratio is achievable for the low frequencies when the streamer is towed at a depth of 15−30 m.
