While drilling gas levels - what are your limits, how are they managed?

29 March 2019 Seeking learning / experiences of how teams get ready to plan design, engineer, and prepare for the physical surface effects of drilling porous permeable GAS reservoirs at high ROP. e.g. 8 1/2" wellbores 20-25% porosity, ROP's > 100ft (30m/hr)

What do you expect to see via the mud loggers gas detectors, 
What are viewed as safe operable limits, best practices to be applied? 
What corrective actions are then needed?
What illustrative well DDR's can be provided to support if best or improper practices then resulted? 
How much of this is covered in current well control examinations, simulations?
FAIL (Failure Always Invites learning) events in this respect?

regards,
