Bulk properties should be measured on all test samples and measured (or estimated) on shows. They are essential for calculation of fluid properties, reserves, and economic value. They also are critical to the design of production methods and refinery processes. (For more on oil and condensate properties, see the chapter on “[[Petroleum reservoir fluid properties]]” in Part 10).

Variations in these properties can be used to test exploration models and evaluate development strategies. All of the basic bulk properties are affected by geological mechanisms that produce variations in oil composition (Table 2<ref name=pt05r154>Tissot, B. P., Weite, W.
