ABSTRACT:
An above packer perforate, test and sample tool for use in obtaining a sample of fluid from a formation reservoir in a well. The apparatus includes a sampler and an actuator cylinder positioned above a packer and a valve body below the packer. An operating mandrel opens a valve below the packer to flow the fluid from a well annulus defined below the packer to a sampling chamber in the sampler above the packer. The operating mandrel is moved in response to a pressure differential between the pressure in the well annulus above the packer and a pressure in the tool. In another embodiment, a second packer may be positioned below the first packer to sealingly engage the well bore below the well formation. A method of sampling fluid from a well formation is also disclosed.
