... ABSTRACT Core samples and well logs serve as crucial sources of petrophysical measurements, each with its own advantages and limitations. Core analysis results are often considered the ground truth when utilized in core-to-log integration studies and static property modelling. Even today...

... predictions were then integrated with traditional reservoir data (well-log data, well-core data, and routine core analysis) to better understand the reservoir. The integration of image data into the reservoir characterization workflow yielded results that can be classified as four rock-type classes correlated...

Researchers qualitatively integrate routine core analysis (RCA) data, special core analysis (SCA) data, mercury injection capillary pressure (MICP) data, petrographic examinations using thinsection images, whole-core computed tomography (CT) scan, core photos along with advanced...

.... The observed resolution is on the order of two centimeters. Later, we integrate resistivity and dielectric permittivity measurements with other petrophysical parameters from the core analysis to refine the formation evaluation results. We combine the resistivity and dielectric permittivity with lithology...

The cleaning process requires that the core samples are restored to their original strongly water wetness before oil migration. This is much more challenging than volumetric clenaing in routine core analysis for measurement of pore volume...

However, since both measurements are different due to their frequency ranges and experimental procedures, the Petrophysicist finds it can be challenging to correlate the two pieces...
