value of zola/wa-290-p/wa-49-r, page-6

Sheepskin

It is easily calculated if you use the experience of what BHP got for Browse.

If you accept the proven reserves (come in Tonga!) of Zola/Bianchi are 2 TCF then Tap's share is 10% or 2 hundred BCF (ie one fifth of a TCF) One fifth of $665M (what BHP got per TCF) equals $130M. (Do you get it?)

Tallaganda (WA-351-P part) likely has 500 BCF (?) (I suppose this will be confirmed by the Tallaganda Appraisal well to be drilled later this year). So Tap's share would be 20% of 500 BCF equalling 100 BCF (or one tenth of a TCF) So Tap's share of Tallaganda would be one tenth of $665 M. That means Tap's share of Tallaganda would be worth $66.5 Million.

Zola and Tallaganda would be worth $130M plus $66M equals $200 million. (I can't put it more simply than that)

NOTE
Of course I could be hopelessly wrong because I am a rank amateur in this field and maybe I have overlooked something quite fundamental.
