Abstract
Method for quantitatively assessing connectivity for well pairs at varying frequencies. A time series of measurements () is chosen for each of the two wells such that the particular measurements will be sensitive to subsurface connectivity if it exists (). The two time series may then be pre-processed by resampling to time intervals commensurate with response time between the two wells (), detrending the measurements (), and detecting and eliminating spiking noises (). Then the time series are transformed to the frequency domain where coherence and phase between the two series are compared for varying frequencies (). This comparison is used to make a determination of connectivity.
