new drill time frame, page-2

Chaps

2day's update should get the interest back in MEO over the nxt 2 weeks. I wish PBR could do a flow test, signs look allright as we go deeper.

Time to take a deep breath & think abt safety from now on. It's good to see PBR call for 'drinks' (i.e, stop drilling, run casing, b4 drilling ahead).


Sequence of events later this week:

- Last casing point (13"): 1860m
- Current Depth (12.25") : 2936m (or 9632 feet)
- Open Hole section: 1076m (~80-87 joints of 9" casing)
- Drill 8.5" section

So next up, they should have pulled out the pipes of the hole,

- Commence running 80-87 odd joints of casing
- Pump cement
- Pressure test BOP (thank god the BOP works on this high pressure gas zone)
- Drill out cement & shoe into the 8.5" section
- Commence drilling to 3200m (or Calypso top)
- Conduct routine flowchk's for any abnormal high gas readings
- Proceed with coring in the Calypso

IMHO they should drill the next part of A#1, i.e 8.5" dia hole with a new mud weight, just 2b safe.

For those keen on formation names, here's the lithostratigraphy of the NWS frm the WADMP website.

Stratigraphy of Carnarvon Basin

What was missing frm the update (perhaps due to the prying eye of the neighbours) was :

- the actual thickness of this overpressure zone,
- pressure encountered in PSI (eg 2300 psi etc)
- gas type (my money is on C1 not CO2).

So we wait b4 the nxt update.

Lets hope they provide a couple more this week, now that would b ideal. However, safety first....
