1st June 2017 - Porosity - A Horrendous Gas Field

A little study whilst waiting for the updated basin model....

I started here with the basics of Looking for Oil & Gas

It Led me to this "With sandstones, a porosity of 18% or more is usually needed for an economic oil reservoir. Gas flows easier than oil, so as little as 12% porosity may be enough for a gas reservoir"
So off I went to check Page 8 of the recent AGM Presentation
With very limited knowledge it looks to me like we have 20% porosity, so further study was needed and so time to go to university of Alabama for 45 minutes to study porosity logs! (A little heavy but so much interesting stuff and worth the time invested)
The first video starts at 8 minutes 50 seconds...


Geophysics: Lecture 8. The porosity logs

Then music to the ears of an Aminex investors!  A little Gem at 39mins 55secs  "If you have a section 100 to 200ft you have a horrendous gas zone and you don't get a lot of those in the world"
Why the music?  Aminex have hit a section 166ft
I Went on from there to Isopach Maps - Top of formation Maps where the second video starts at 6 minutes 41 seconds




 Geophysics: Lecture 9. Isopach maps. Top of formation maps
As a layman, I found it all very interesting and it makes you realise things aren't about throwing a dice in the air but very careful calculations have to be completed to complete a basin model.  It would be interesting to have the direct views of a Geo Physicist about what we have but meanwhile investors eagerly await the production of the new basin model.
So, as said, Aminex has found a 51Mtr (166ft) zone and as Dr Doug Haywick of the University of Alabama is pointing at a Horrendous Gas Zone being between 100 and 200ft, I'm really not surprised that the language from the board of directors has been of a "Company Changing"  -  "Country Changing"  -  "World Class Find".
