Technical Abstract

Wavefield driven reservoir analysis

Back to Technical Content
Reservoir analysis of seismic data is performed on migrated seismic images, which represent the spatial variability of the medium’s reflectivity. Intuitively, the process of migration rotates the wavelet so that it is normal to the imaged reflectors. Processes used in reservoir analysis such as deconvolution, inversion and warping for time-lapse analysis need to follow the structure of the data. The traditional 1D (vertical) convolutional approach does not honour this directivity. We introduce a wave equation based approach which provides an effective platform for structurally consistent reservoir analysis. This includes applications such as wavelet extraction, elastic inversion, warping and 4D time-strain inversion.
