摘要:
A system and method for estimating an occurrence of a water breakthrough in a production well is provided that includes estimating, at least periodically, a measure of water in the fluid produced from one or more production zones and estimating the occurrence of the water breakthrough utilizing at least in part a trend of the estimated measures of the produced fluid. A controller determines one or more actions to be taken to mitigate an effect of the water breakthrough and may automatically initiate one or more such actions. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

The present invention provides a method and apparatus for determination of the quality of a formation fluid sample including monitoring permeability and mobililty versus time to determine a filtrate contamination level, single phase state without gas and solids in the formation fluid, as it existed in the formation and the determination of laminar flow from the formation. The present invention also enables determination of an optimal pumping rate to match the ability of a subsurface formation to produce a single phase formation fluid sample in minimum time. The method and apparatus also detect pumping problems such as sanding and loss of seal with borehole.
