[boussis]

Hi Friends,

i hope you are doing well,

what do you think on completing a gas well with 4 1/2 tubing inside 9 5/8 casing ?

i know the best way is 4 1/2 inside 7in casing .

Please i need a response sooner i'm really in need to know that.

Thanks in advance

Is nothing wrong with that except maybe.... the costs.
