1. n. [Formation Evaluation]
The set of measurements normally carried out on core plugs or whole core. These generally include porosity, grain density, horizontal permeability, fluid saturation and a lithologic description. Routine core analyses often include a core gamma log and measurements of vertical permeability. Measurements are made at room temperature and at either atmospheric confining pressure, formation confining pressure, or both. Routine core analysis is distinct from special core analysis (SCAL). Recommended practices for routine core analysis are available in the API document RP40.
