Drawdown

Using an equation of state to predict the effects of producution decline on a reservoir composition. Also, examining the importance of compositional complexity.

###
The Drawdown experiment

Define a drawdown function that simulates the production of a reservior which results in lowering of pressure. The object is twofold:

1: to see how density and GOR vary during production, and

2: to see how the specification of the mixture (i.e., how many pseudo-components used) affects the prediction

#####
Predictions using all components

Flash the mixture at repeatedly lower-pressures

Examine density

####
2) predicting using a C15+drawdown

The Function used to produce the compositions is derived here.

Examine density

####
3) predicting using a C7+drawdown

Method

The Function used to produce the compositions is derived here.

Examine density

####
Compare the plots

#####
Compare GOR

#####
Compare vapor densities
