ØØ This model provides an example of a detailed engineering
ØØ model for calculating the production capacities of an oil and
ØØ gas well. The calculations are based on a standard set of
ØØ equations that can be found in any petroleum engineering manual.

ØØ ===================================
EXPONENTIAL DECLINE=(INITIAL PRODUCTION-BEGINNING PRODUCTION)/ '
EFFECTIVE DECLINE RATE
EXPONENTIAL DECLINE PRODUCTION = EXPONENTIAL DECLINE - '
PREVIOUS EXPONENTIAL DECLINE
EFFECTIVE DECLINE RATE=-NATLOG(1-DECLINE RATE)
BEGINNING PRODUCTION=INITIAL PRODUCTION * '
NATEXP(-EFFECTIVE DECLINE RATE * YEARS PRODUCING)
CUMULATIVE PRODUCTION=EXPONENTIAL DECLINE PRODUCTION + PREVIOUS
OPERATING COSTS=EXPONENTIAL DECLINE PRODUCTION * COST PER BARREL
