Abstract: A drill stem test conducted through the drill string of a wireline coring system using a downhole tool comprising test zone packers, a valve packer, a latching assembly with a clump valve and main valve, all of which are conveyed on the wireline with a communications cable and inflation tube, to seat in the core barrel. Gas pressure drives the liquid level in the drill string down to a suitable test level which is retained by inflating the packer system to seal a valve packer within the drill string, and isolating the test zone using single or dual packers. The compressed gas is relieved from the drill string leaving it unpressurised and with a depressed liquid level therein. A valve can be opened by raising the drill string to induce inward fluid flow, and after a flow period the valve is shut by lowering the drill string. A pressure recovery process then takes place, in which the pressures are measured by downhole transducers and transmitted to surface via the communications cable.
