Event Frame End Trigger based on time

Hi All,

 

I would like to analyse gas well behaviour in the first 48 hours after a well is restarted. To capture the restart event a trigger is created based on when choke valve is >1% open.

 

Once the choke is at 100% I would like the event window to be a certain time period (say 48 hours). How can I write an end trigger to capture this data?

 

Appreciate the help.
