... law becomes invalid and any estimate of water saturation using Archie's equation will most likely yield erroneous results. Many scholars and researchers have attempted to come up with models linking well logs and laboratory data to estimate water saturation in complex pore systems. To appropriately...

... are placed in a fine-scale grid with block dimensions of 5ft x 5ft x 1ft. After one year of water injection, the simulated saturation-depth profile around the water injector was found to compare favorably with the analytical BL profile. The study included sensitivities varying (i) vertical (k v...

... Abstract Pulsed neutron spectral carbon/oxygen (C/O) logging is a widely used shallow measurement for time lapse reservoir saturation monitoring. Because of its shallow depth of investigation, its measurement is affected by several factors among which the near wellbore logging environment...

... Abstract Petrophysical models are used to estimate formation water saturation and salinity from dielectric dispersion data. These models are sensitive to other attributes of the formation such as wettability. Previous studies, analyzing different parameters of dielectric petrophysical models...
