re: Ann: Encouraging Gas Flow Recorded at Mt ... haasko,
It says "The well air-drilled into the objective Heavitree Formation at a depth of 2,140 metres below rotary table."
It also says they stopped drilling to evaluate gas shows multiple times. This clearly implies they were air-drilled, and flow tested while air-drilling. They did not stop to trip out, run logs, then trip back in with DSTs, they certainly did not stop to log and run a DST at 2144m, then run back in the hole with the drill bit, drill another 12 metres to 2156m, trip out of hole again and back in with DST tools to test the second zone.
If they had to do that, they would just waited until after TD, and after they had run logs to go back in and flow test. But this rig incident occurred DURING wireline logging. You don't test zones until you have wireline logs because you can't be sure what you're supposed to be testing. The only way you would is if you used off-bottom DSTs - which are the mud-drilling equivalent of air flow tests, they don't tell you any information about what flow is coming from what zone. But they clearly say 'flow tests' and not 'drill stem tests.'
What they have done is common practice with air-drilling and makes use of its prime advantage - there is no mud in the hole that you need to displace to flow test.
The fact they stopped during drilling to run two flow tests only 12m apart before wireline logs were completed clearly indicates, beyond all reasonable doubt, that these were tests conducted during air drilling.
I honestly don't see where the ambiguity in this announcement is.
