Abstract

An apparatus for obtaining fluids via a well includes an outer tubing disposed in the well and set at a shallow reservoir comprising a first fluid, and an inner tubing disposed concentrically within the outer tubing and set at a deeper reservoir further downhole than the shallow reservoir. The deeper reservoir has a second fluid, where a first packer is disposed between the outer tubing and an external tubing and disposed above the shallow reservoir, and a second packer is disposed between the outer tubing and the inner tubing and disposed above the deeper reservoir. The second packer blocks an annulus through which the first fluid is extracted via the outer tubing. The first fluid is obtained from the shallow reservoir and the second fluid is obtained from the deeper reservoir by drilling via the well.
