Table 12-3 from Kamal, et al. [1995] illustrates the type of information
that can be obtained at the Mega Scale level from well test data. The table also
notes the time in the life of the project when the well test is most likely to be
ran. It is usually necessary to run a variety of well tests as the project matures.
These tests help refine the operator's understanding of the field and often
motivate changes in the way the well or the field is operated. Additional
information about well testing can be found in literature sources such as
Matthews and Russell [1967], Earlougher [1977], and Sabet [1991],
