Abstract
Summary In the development of shaly sand saturation models, core data are of exceptional value. These data are required to check the descriptive and predictive power of existing models and compare them with new concepts. This paper aims to add to the modest set of generally available core data on shaly sands by presenting a variety of special core-analysis measurements on a number of shaly sand core samples. The experiments presented here include standard petrophysical measurements, continuous injection (CI) resistivity measurements (at ambient and elevated temperatures), nuclear magnetic resonance experiments (t1 and t2 acquisitions on fully brine-saturated samples; t2-diffusion measurements with an external magnetic gradient on partially brine-saturated samples), and scanning electron microscopy (SEM) images that have been subjected to image analysis.
