Packer, slug, and recovery tests are common procedures for determining the hydraulic conductivity of unconfined formations of low permeability. The volumes of water injected or removed from the borehole are small, so that the water table remains horizontal and the flow is steady. The flow problem is solved by source distributions along the well axis. A simple numerical method and numerical results covering a wide range of the parameters of the problem are presented. The main limitation of the method is the requirement that the active portion of the well length should be much larger (say, 50 times) than the well radius.
