Statistical Methods for Estimating Petroleum Resources
within a facies wedge can be allocated into either a wedge-base, wedgemiddle, wedge-top, wedge-edge, or subunconformity play. Each such
play type is associated with a play-level geological factor. White (1980)
summarizes 1150 plays in 80 productive basins of the free world and
presents the relationships between play characteristics and the chances
of the play containing hydrocarbons. The results are reproduced in
Table 5.2.
