hot to control flow of the well through tubing & Anulus

[ENG BAHA]

Hi Friends
My company decided to flow some wells to produce separately from tubing and annulus. we will use SSV for tubing but for Annulus what you suggest to control the well taking into consideration the casing size is 7'' and two zones will be completed (packer in between) the bottom one will produce via tubing and top through annulus.
please appreciate your help to provide me with schematic on how we can perform this since we can’t use dual packer in 7'' casin.

I do not know any equipment or ever seen a well in which the annular flow is controlled by means or SSV or similar. However there are some questions which arise.
Has your lower zone H2S or CO2? Why the SSV?
What about the upper zone that you want to produce up annulus? Does it have H2S or CO2? If yes, even if such a device exist, H2S or CO2 produced will kill your casing and the well might be very expensive to repair if possible. If there is no H2S or CO2, then you can produce without SSV.

Thanks a lot Yengineer, upper one hasnt CO2/H2S but however due to high rate was asked to install means of safety control.
i got that some service companies have Anular safety valve used for such this cases i.e. Haliburton and SLB.
