Ann: Encouraging Gas Flow Recorded at Mt Kitty Ex, page-32

re: Ann: Encouraging Gas Flow Recorded at Mt ... jentolow,

As I said to stockrocker in my reply above, flow tests in air-drilled wells conducted during drilling are not flow tests of isolated zones. They are flow tests of the whole well that is open to that point.

So if the third and fourth flow tests provided comparable flow rates to the second flow test, it suggests the deeper zones are not providing any additional flow. If they were flowing, the flow test would be higher than the second flow test, because you'd be getting the gas flow from the second test plus the extra flow from the deeper zones.

We're not seeing that, which implies the bottom zones are not contributing much.

After logging they will identify on the logs the likely zones from which gas came, and they will use a tool like a DST or MDT which can actually isolate a zone with packers. Then they will be able to separately measure each zone. The deeper zones may flow some minor but it sounds like the bulk of the flow is in the top 15m of the Heavitree. That's not usual - the bulk of the gas appears to be sitting directly below the seal.
