Special core analysis


In the petroleum industry, special core analysis, often abbreviated SCAL or SPCAN, is a laboratory procedure for conducting flow experiments on core plugs taken from a petroleum reservoir.
Special core analysis is distinguished from "routine or conventional core analysis" by adding more experiments, in particular including measurements of two-phase flow properties, determining relative permeability, capillary pressure, wettability, and electrical properties.
Due to the time-consuming and costly character of SCAL measurements, routine core analysis data should be inspected thoroughly to select a representative subset of samples for SCAL.
