THE TOTEM AVAILABLE DAILY INJECTION QUANTITY RULES AND FORMULA

 

%TMAC = Current Inventory/TMAC

 

------------------------------------

 

If the %TMAC is < or = to 89.30%

then set the %TMDIQ = 100%

 

------------------------------------

 

If the %TMAC is > 89.30% and < 100% then

%MDIQ = (5686.7) - (%MAC * 108.36) +

(%MAC^2 * 0.5167)

 

------------------------------------

If the %TMAC is = to 100%

then set the %TMDIQ = to 0%

 

------------------------------------

 

TADIQ Calculation

 

TADIQ = (%TMDIQ/100) * TMDIQ

Round to the nearest whole Dekatherm (an integer)

 

------------------------------------

 

Notes: (1) In the context of this formula, the %TMAC and %TMDIQ

values are taken as whole numbers, and not as decimal

only numbers (i.e. if the value is 40% use 40.0 not .40,

or if it is 36.1234% use 36.1234 not 0.361234).

 

(2) The coefficients are entered with four decimal places.

The table is calculated with four decimal places, and

then rounded for display purposes.

 

(3) All calculations are initially performed utilizing four

decimal places. The final TADIQ, however, is rounded to

the nearest whole number.
