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.
