摘要
The abundance and distribution of brine and decane are determined from T-1 distributions at different stages of a water-flood test in water-wet and oil-wet chalks. The T-1 distributions generated from multi-exponential decomposition of inversion-recovery data provide more information than obtained from stretched and hi-exponential fits. Chalk samples because of their uniform pore size and ideal sedimentary rocks for NMR investigations of wettability since water and decane interactions with pore walls of differing wettability are easily distinguished.
