Method and system for automated multi-zone downhole closed loop reservoir testing

A method of performing an operation in a wellbore, comprising:

• running a toolstring in a wellbore that extends from a surface and penetrates a hydrocarbon-bearing formation, the formation including an upper zone and a lower zone, wherein the toolstring includes a plurality of tools to perform an operation in the wellbore, the tools including:
• a first packer and a second packer;
• a first fluid valve and a second fluid valve;
• and
• a fluid flow device, wherein the fluid flow device includes a cylindrical housing having a wall defining an internal passageway for an axial fluid flow through the housing, and a plurality of ports extending through the wall to provide a path for a radial fluid flow to exit the internal passageway when the ports are open;
• positioning the toolstring in the wellbore so that the first packer and the second packer straddle the upper zone, the first fluid valve and the second fluid valve straddle the upper zone, and the fluid flow device is adjacent the upper zone;
• setting the first packer to create a fluid flow barrier between the upper zone and an annulus of the wellbore surrounding the toolstring;
• setting the second packer to create a fluid flow barrier between the upper zone and the lower zone;
• closing the first fluid valve to prevent a fluid flow through the toolstring to the surface;
• opening the second fluid valve and the ports of the fluid flow device to create a closed path for the hydrocarbon fluid to flow from the lower zone and into the upper zone;
• and
• perforating the lower zone.
