Abstract: A length of coiled tubing is installed into a horizontal side-track wellbore. The coiled tubing has a pre-perforated section that defines perforations between a first end of the perforated section and a second end of the perforated section. The perforated section is positioned to align with a zone of interest within the horizontal side-track wellbore. A first isolation packer surrounds the length of coiled tubing. The first isolation packer is attached to the length of coiled tubing at the first end of the pre-perforated section. A second isolation packer surrounds the length of coiled tubing. The second isolation packer is attached to the length of coiled tubing at the second end of the pre-perforated section.

Abstract: A first layer of the multi-layered reservoir is produced through a coiled tubing production string. The coiled tubing production string is located within a wellbore that includes a first horizontal section within the first layer. The coiled tubing production string includes a packer at a downhole end of the coiled tubing production string. The packer seals an annulus that is defined by an outer surface of the coiled tubing production string and an inner surface of the wellbore. The coiled tubing is retracted from the first layer of the multi-layered reservoir to a second layer of the multi-layered reservoir. The second layer is uphole of the first layer. The first layer is sealed from the second layer. The second layer produced through the coiled tubing production string. The coiled tubing production string is located within the wellbore that includes a second horizontal section within the second layer.
