  • Patent number: 5799733
    Abstract: An early evaluation system with pump for servicing a well and taking fluid samples and measurements. In each of the embodiments, a formation pump is actuated to flow fluid from the well formation below a packer element engaged with the borehole into a sampling tube. Fluid samplers and recording instruments may be in communication with the sampling tube. In one embodiment, the pump is mechanically actuated by rotation of the tool string. In another embodiment, the pump is hydraulically actuated and has a hydraulic motor connected thereto. In this hydraulically acutated embodiment, fluid pumped down the tool string actuates the hydraulic motor and thereby further actuates the pump. Other pump embodiments are also disclosed. In still another embodiment, the apparatus may be incorporated into a drill string so that a drilling operation may be carried out and immediately followed by a fluid evaluation operation.
