Ann: Change in substantial holding from MIN, page-200

@Mikey74
If you want to do the excercise, you could do this...using NWEs numbers.

For Lockyer and each of Leads A-F...you could multiply the Areas (see tale below) in km2 by 70bcf/3km2 and 110 bcf/3km2 - numbers they gave us. Make sure you use km2 not 3km2. For Lockyer use the companys 102km2 figure.
Then multiply by 0.8 recovery factor.Then multiply by 94% (Hydrocarbon gas). Assume there is no condensate.
And you will get a high and low range of recoverable hydrocarbon gas. That will e a conceptual figure.
Then you could use Lambo/Audi's rule of thumb of $2/GJ for domestic gas and also use something like $4/GJ for LNG gas and see what numbers you come up with.
It is a simplistic exercise, with a bit of training, most CFOs and CEOs are even capable of this type of maths.
Pay particular attention to Springy Creek in the below picture...Nothing in the Lead Tables about that...but I might have something to post soon.
