Abstract:
The well condition during gravel packing is monitored and the gravel distribution condition is sent to the surface in real time through the preferred technique of a fiber optic line that wraps around the screens directly or indirectly on a surrounding tube around the screens. The fiber optic line has a breakaway connection that severs when the completion inner string is removed. A production string can then be run in to tag the fiber optic line through a wet connect to continue monitoring well conditions in the production phase. The fiber optic line can also be coiled above the packer so that relative movement of the inner string to the set packer can be detected and communicated to the surface in real time so as to know that the crossover has been moved the proper distance to, for example, get it from the gravel packing position to the reverse out position.
