Production from each zone is segregated by running two tubing strings with packers inside the single string of production casing, or by ruunign one tubing string with a packer through one zone while the other is produced through the annulus. In a miniaturised dual completion, two separate 4.5-inch (11.4-centimetre) or smaller casing strings are run and cemented in the same wellbore.
