An application of fluid mobility attribute for permeability prognosis in the crosswell space with compensation of the reservoir thickness variations

摘要

We have considered a permeability prognosis in the crosswell space within the Middle Jurassic Ju_(3?4) Formation in the southern part of Western Siberia. The prognosis was based on core measurements, well log analysis, and seismic attribute calculations. We have estimated the formation permeability in the wells, calculated seismic attribute proportional to fluid mobility from the 3D seismic data, and eliminated the influence of the reservoir thickness variations. The correlation between appropriate seismic attribute values and Ju_(3?4) formation permeability was used for the prognosis and mapping the permeability in the crosswell space.
