This 80 choke question seems to have everyone stumped!
I have asked several people that work in the oil & gas industry and no one knows what it means!

Granny, I think I provided a potential answer on the previous page.

Some of the auto chokes the producers are using show percentages when first installed until they have updated the software to show 64ths. There is no such thing as an 80/64 choke. I know this because I deal with these wells on a daily basis. Well tester here!

Generally speaking, the larger the choke the greater the flow. A flow line choke is intalled to allow the operator to control the output of the well to the best "reliable" flow rate. A well that is improperly controlled may be damaged by the flow rate and pressure drop at the completion (down hole). This damage can include breakdown of the formation & completion, sometime to failure. Traditionally this usually means the well will become plugged by formation material, however, there may be some different characteristics with these horizontal gas well completions that I am not aware of.

Decreasing the size of the choke allows the operator to reduce flow as required to respond to market conditions.

Each well will have its own characteristics which will require the proper size choke.

128/64 = 2 inches.
