Geological heterogeneity in hydrocarbon reservoirs is normally related to variability in depositional facies, diagenesis and structure. On the Loppa High, Norwegian Barents Sea, reservoir quality in prospective Upper Palaeozoic carbonates is consider

In this paper, we review most major filtering approaches to texture feature extraction and perform a comparative study. Filtering approaches included are Laws masks (1980), ring/wedge filters, dyadic Gabor filter banks, wavelet transforms, wavelet pa

The design of filters for texture feature extraction is addressed. Based on a new feature extraction model, optimization approaches utilizing various feature (energy) separation criteria are developed. Both two- and multiple-texture problems are addr

Seismic attributes have been a common tool in seismic data analysis since the mid to late seventies. Seismic attributes may highlight geological or geophysical effects, thus leading to a quicker analysis of the data. In the early works, seismic attri

In this chapter, a simplified method for mapping objects based on the level set method is introduced. Level set and marching methods are used to map connected volumes within 3D seismic data. The simpler marching method solves the stationary problem s

A method for discriminating between different reservoir flow models using forward modeling and time-lapse seismic is presented. A rock-physical model is used in order to generate synthetic time-lapse acoustic responses based on flow model predictions
