Ann: Strong Gas Shows Continue at Borba Discovery, page-361

At high mud weights no gas will flow into the well bore .
The background gas comes from the gas trapped in the drill cuttings that is released into the drilling fluid as the cuttings move from the high pressure at the bottom of the hole to atmospheric pressure at the surface.
Background gas does not measure either porosity or permeability .
It just means there is gas in the rocks being drilled and there is some porosity even though it could be very small.

At TD they will run electric logs that measure porosity and resistivity of the formations.
They may or may not run a tool that can take a sample of the pore fluids in zones of interest shown on the electric logs.
If the logs show likely economic pay zones they will run and cement casing or a liner .
I very much doubt that they will do a DST in open hole .

After the cement has set they will test the zones of interest by running tubing and perforating the casing.
They will progressively test the well from the bottom zones moving up .
They may not test all the zones if they get big flows from the lower zones.

I do not know if they will use the drill rig to flow test.
when they drilled Dempsey they demobilized the drilling rig after cementing casing and brought in a smaller cheaper day rate workover rig to do the testing .

They drill wells like they are spending their own money .
Not quickly but frugally.
