Hi Marc,

Attached you will find the test doc with the spreadsheet filled in. The regulator at the gas panel is set to about 8. Which is where it started.

Best,
Ezekiel

Hi Marc,

Ok, I think we are good to do the test now.

Hi Marc,

I’m not sure if we can run today. I am not used to changing the regulator so I was trying to coordinate with Chuck. I’ll let you know.

Hi Holly,

Here is a formalized plan for the test. I have verified that all pressure and flow monitoring is up and running.

Marc

Hi Holly,

Lets make the pressure range from 0 to 8 psi. I just verified that the regulator output pressure is 8 psi.

Hi Holly,

The logging is back online. Tomorrow is fine, can you email me before you start the test so I can verify the WEDM/MYA is working before you start.

Hi Marc,

Sounds good-just let me know when you are ready. We could do this tomorrow.

Subject: [Dsg-halla_gem] Regulator test

Hi Holly,

I need to coordinate a test with your group. I need to get data on the flow as we change the pressure regulator from 0 to 9 psi in steps. This will help with the development of the overpressure protection setup using the mineral oil bubblers Brad provided.

I am waiting for the network folks to fix an issue with WEDM and MYA, hopefully that will be fixed soon and we can set up  the test.

Basically I need to lower the pressure regulator to 0, record the baseline flow, then change the regulator to 1 psi for a minute, then 2 psi for a minute...all the way to the current setting of 9 psi.

I'll email you when the logging is back online so we can set it up.

Regards,

Marc
