An optical system for acquiring fast spectra from spatially channel arrays includes a light source for producing a light beam that passes through the microfluidic chip or the channel to be monitored, one or more lenses or optical fibers for capturing the light from the light source after interaction with the particles or chemicals in the microfluidic channels, and one or more detectors. The system may scale an image value at each location using the net signed fractional modulation value at each location. The method identifies the sequence from the reference sequences such that the subject in performs the closest action to that observed. Both imagers are scanned synchronously, and the corresponding output signals are digitized. The system for field wide reservoir management comprising a CPU for processing collected field wide reservoir data, generating a resultant desired field wide productioninjection forecast and calculating a target production rate for one or more wells and one or more down hole productioninjection control devices.
