===Conventional or plug analysis===

Continuous cores can be analyzed by conventional or whole core procedures, but ''conventional core analysis'' is most frequently used.<ref name=pt05r38 /> This procedure employs a small sample to represent an interval of core and produces acceptable results when the pore system is relatively homogeneous. Conventional core analysis plugs are usually collected once per foot or three to four times per meter.<ref name=pt05r114>Monicard, R. P., 1980, Properties of Reservoir Rocks—Core Analysis: Houston, Gulf Publishing Company, 168 p.</ref> Variations in pore system development or lithology require more frequent sampling. Sample density should be adequate to define net pay, hydrocarbon-water transition zones, contact levels, and formation boundaries. Sampling can be done statistically at the mid-point of each foot or the most representative sample in each foot can be selected.
