Re presentation, I found interesting, worth reading till the end. Dman. p.s I am NO expert so happy to read any Thoughts on the below
Hi M1


Thanks for the reply........................ at 3:18am in the morning .... have you got insomnia????


I have just re-read the presentation from AOI and there they have released the results of their log readings from the log cores. I am surprised that they were allowed to release these as they give us a very good idea as to what to expect from the flow testing.

See: https://docs.google.com/folder/d/0B-tbNiS5siSjS296bXQ5SG45UEU/edit?pli=1&docId=0B-tbNiS5siSjMFZ6dzBtWVJueVU


To understand what all this means you need to have a basic understanding in geology, so at the risk of offending people on this board I apologise in advance for teaching you to suck eggs but I am sure there are others who are not so Knowlegeable.

For any well to be successful, the rock/sand that is drilled into has to have good properties of both 2porosity" and "permeability".

Porosity consists of the tiny spaces in the rock that hold the oil or gas. For example a sandstone rock that is deemed to have 10% porosity means that the gaps in between the rock is 10% oil bearing whilst the other 90% is the actual rock and hence of no commercial value.

Permeability is a characteristic that allows the oil and gas to flow through the rock. It is a measure of the resistance a rock has to the flow of fluid through it.If it takes a lot of pressure to squeeze fluid through a rock, that rock has “low permeability” or “low perm.” If fluid passes through the rock easily, it has “high permeability,” or “high perm.” The permeability of a rock is measured on a scale from O to 1000 and is expressed in millidarcys where 0 means nothing moves and 1000 is virtually free flowing.

The benchmark or rule of thumb in the industry for producing a decent well requires the well to have as a minimum: 8% porosity and a minimum of 10 millidarcys permeability.

Now look at the figures quote on the AOI presentation. Bear in mind that these results are taken from the immediate vicinity of the drill hole and hence may vary as you move out into the basin but they are a very good indication of what to expect.

Basically as I see it :-

a) The 100m Ngamia column and the Twiga 30m column appear to have excellent porosity and permeability qualities and should provide for a very good flow rate.

b) The secondary resevoir at Ngamia (40m) column has adequate porosity and permeability qualities and should provide for recovery but nowhere near the rates as that of the 100m column described in (a) above.

c) The 796m fractured rock play does not have the minimum requirements for recovery under normal practices. This still may have a commercial value though if it is possible to use an alternative recovery means such as the employment of fracking or horizontal drilling.


All in my humble opinion of course but those 100m Ngamia and 30m Twiga columns are looking very good.
