Fiberoptic Systems and Methods for Formation Monitoring

摘要: A disclosed formation monitoring system includes a casing that defines an annular space within borehole. An array of electromagnetic field sensors is positioned in the and configured to communicate with surface via fiberoptic cable. computer coupled cable receives said measurements responsively derives location any fluid fronts vicinity such as approaching flood front enable corrective action before breakthrough. method includes: injecting first into reservoir formation; producing second from borehole; collecting between borehole, communicating interface one or more cables; operating on locate fluids.
