primary target formation: triassic carbonates.

As Jpr's primary target is a Triassic Carbonates zone I thought I'd see what facts were available on Carbonate Reservoirs.

Some interesting facts from Schlumberger........

" Carbonate Reservoirs

The significance of carbonate reserves

With about 3,000 billion barrels of remaining oil in place and more than 3,000 trillion cubic feet of gas in place, carbonates present us with some of the greatest challenges and opportunities to develop new technologies and processes or refine existing ones.

To meet rising global energy demand and consumption, sustaining production from existing fields and increasing recovery factors will be critical. To do this, it will be necessary to improve our understanding of fluid flow mechanisms and reservoir systems.
Market size

* More than 60% of the world?s oil and 40% of the world?s gas reserves are held in carbonates.
* The Middle East has 62% of the world?s proved conventional oil reserves; more than 70% of these reserves are in carbonate reservoirs.
* The Middle East also has 40% of the world?s proved gas reserves?; 90% of these gas reserves lie in carbonate reservoirs."
