Scientific paper

The spatial cross-correlation and power spectra of porosity and log(permeability) sequences are analysed for a total of 750 m of reservoir rock drill-core from four vertical wells in the Brae Formation, an important coarse-grained clastic North Sea hydrocarbon reservoir rock. The well core sequences are 80+/-4 per cent cross-correlated at zero lag and have power-law-scaling spatial power spectra S (k )~1/k β , β ~ 1+/-0.4, for spatial frequencies 5km-1
