Abstract
A method for guiding an untethered measurement device used in a subterranean well ascending from a space provided by a casing and a terminus of a production conduit. The method includes the step of securing a swellable packer radially on an exterior surface of the production conduit at or proximate to the terminus of the production conduit. The swellable packer is in a non-swollen configuration. The method includes the step of deploying the production conduit into the subterranean well to a target depth. The method includes the step of contacting the swellable packer with a fluidic component at the target depth such that the swellable packer transitions to a swollen configuration.
