reports are out, page-67

From Dec quarterly cash - sales = $2.135mill
From Dec quarterly activity page 4/16 condensate sales = 35,941bbls - which at a round number AU$100 per bbl = $3.59mill
So either my use of $100 round number is a wild exaggeration - or payments come in irregularly - or both.
Then there is gas sales of 694TJ
In the EGO Stockbrokers brief announced 27 Sep 2012
Page 2/5 point 9 "Gas price robust between $6.50 - $10 an MCF (GigaJoule)"
Now a TeraJoule is 1,000 GigaJoules -
so taking the lower end price range and knowing that ALCOA have made advance payments - I am guessing EGO might be due $4 per GJ on gas supplied now.
That would total 694 x 1,000, x $4 = $2.77mill for the Dec Quarter. Now that alone exceeds the $2.135mill received by EGO. So maybe payments for the gas are irregular.
Or is EGO supplying gas free until the advance payments have been "worked off"
So are there substantial overhang payments due EGO from last quarter?
Apologies if I have made a major mistake.
Was this any help?
