  • Methods and apparatus for collecting a downhole sample
    Patent number: 7841402
    Abstract: Apparatus and methods for collecting a downhole sample are provided. The method may include introducing a flowable sealant to a borehole wall portion, modifying a formation system mobility using the flowable sealant, and receiving the downhole sample using a sample receiving port positioned proximate the borehole wall portion. An apparatus includes a formation sampling member having a sample receiving port for receiving the downhole sample, and an inhibitor that includes one or more of an activator and an injector.
    Type: Grant
    Filed: April 9, 2008
    Date of Patent: November 30, 2010
    Assignee: Baker Hughes Incorporated
    Inventors: Daniel T. Georgi, Aleksandr A. Kashevarov, Artem V. Manakov
  • Methods and apparatus for collecting a downhole sample
    Patent number: 7836951
    Abstract: Apparatus and methods for collecting a downhole sample are provided. The method may include monitoring a flow path parameter, introducing a sealant to a borehole wall when the flow path parameter satisfies a first predetermined condition, and collecting a downhole sample when the flow path parameter satisfies a second predetermined condition. An apparatus may include a formation sampling tool having a flow path, an inhibitor coupled to the formation sampling tool, a sampler coupled to the formation sampling tool, and a selector that selects one or more of the inhibitor and the sampler when a parameter of the flow path satisfies a predetermined condition.
