Abstract
One embodiment of the present disclosure describes a test assembly including an inflatable packer. An internal control sleeve controls flow of drilling fluid through an inflation port to inflate and deflate the packer. A shifting tool run on a slick line moves the sleeve. The packer has one end attached to an external sliding sleeve which moves upon packer inflation to expose a formation fluid port through which formation testing is performed. After testing and packer deflation, a circulation port may be opened to recover produced fluids up the drill string. A second sleeve controls flow through the circulation port and is controlled by a second shifting tool run on slick line. Other embodiments include a circulation assembly with a sliding sleeve opened and closed by one shifting tool to control circulation and the sliding sleeve itself and its operation.
