Dielectric measurements and interpretation, introduced with great promise in the 1980s,
have not found widespread use owing to measurement limitations, moderate accuracy, and …

A novel correlation identifying inefficient drilling conditions is presented using experimental
and field data. Historically, Mechanical Specific Energy (MSE) has been used to improve the …

So-called Archie rocks are characterized by a resistivity index (RI) versus water saturation
that plots as a straight line on log-log scale, the line's slope being equal to-n where n is the …

Hydrocarbon-bearing conventional formations, mudrock formations, and source-rock
formations generally contain clays, pyrite, magnetite, graphitelike carbon, and/or other …

Dielectric spectroscopy can be used to identify the fluid properties of complex reservoirs, but
no existing model can accurately describe the dielectric dispersion behavior of rocks in a …

Dielectric logging was introduced in late 70s to mostly measure water filled porosity in the
flushed zone independent of water salinity and Archie exponents m and n. Although the …

Results from experiments on three identical samples of oolitic limestone show the systematic
effects of wettability and fluid saturation on nuclear magnetic resonance (NMR) and …

Techniques for determining formation characteristics use measurements of dielectric
permittivity at a number of frequencies. Determined characteristics include the vertical and …

Reservoir rock wettability is an important parameter to consider for oil recovery optimization.
The great majority of sandstone formations is known to be strongly water-wet. In contrast …
