Methods and systems for completing multi-zone openhole formations

A method for completing multi-zone, openhole formations, comprising:

• placing a gravel pack assembly within an uncased borehole, wherein the gravel pack assembly comprises:
• a first sand control extension;
• a first sand control screen disposed adjacent the first sand control extension;
• wherein the first sand control extension comprises a first flowpath that is selectively opened and closed;
• a second sand control extension disposed adjacent the first sand control screen, wherein the second sand control extension comprises at least a second flowpath that is selectively opened and closed;
• a second sand control screen disposed adjacent the second sand control extension;
• a first isolation packer disposed between the first sand control screen and the second sand control screen;
• a second isolation packer disposed between the first isolation packer and the second sand control screen;
• and
• a lower seal disposed adjacent the second sand control screen;
• disposing the first sand control extension and the first sand control screen at least partially within a first hydrocarbon bearing zone;
• disposing the second sand control extension and the second sand control screen at least partially within a second hydrocarbon bearing zone;
• setting each of the isolation packers;
• disposing a service string within the gravel pack assembly;
• aligning the service string with the second sand control extension;
• pumping a gravel slurry through the second flowpath to an annulus formed between the gravel pack assembly and the uncased borehole;
• discontinuing the pumping of the gravel slurry to the second sand control extension;
• moving the service string away from the second hydrocarbon bearing zone thereby closing the second flowpath;
• aligning the service string with the first sand control extension;
• and
• pumping the gravel slurry through the first flowpath to the annulus.
