ABSTRACT:
Apparatus and method for testing an open-hole well and obtaining a fluid sample therefrom. The apparatus comprises a compression packer on a drill pipe. Disposed in the drill pipe is a housing, defining a surge chamber therein, and a closure valve in communication with the surge chamber. A fluid sampler is in communication with the surge chamber. In operation, the packer is placed in a set position by setting down weight. The closure valve is pressure actuated so that fluid is flowed from a formation or zone of interest into the surge chamber and then into the sampler. By opening a housing valve at an upper end of the surge chamber, formation fluid may be forced back into the formation or zone of interest by a bull-heading operation. In a preferred embodiment, the packer and drill pipe are disconnectable from the remainder of the apparatus, and the packer is drillable.
