Abstract: A method of estimating the instantaneous crop yield ?2(t) at time t in a field, during harvesting with a harvesting machine that operates by cutting and/or controlling the crop and has a crop mass flow sensor that measures the mass flow rate of crop processed by the machine at a location remote from that at which the harvesting machine cuts the crop and generates a signal {dot over ({circumflex over (m)}out(t) indicative thereof, including the steps of: generating a mass flow rate signal {dot over ({circumflex over (m)}out(t) using the sensor;generating an area rate signal ?(t) indicative of time domain variations in the area of the field harvested per time unit;filtering the area rate signal ?(t) using a function P(s) representative of the dynamics of the harvesting machine to generate a filtered area rate signal ?2(t); andusing the filtered area rate signal ?2(t) for deriving from the mass flow rate signal {dot over ({circumflex over (m)}out(t) a yield per area unit ?2(t).

Abstract: A method of real time field wide reservoir management comprising the steps of processing collected field wide reservoir data in accordance with one or more predetermined algorithms to obtain a resultant desired field wide production/injection forecast, generating a signal to one or more individual well control devices instructing the device to increase or decrease flow through the well control device, transmitting the signal to the individual well control device, opening or closing the well control device in response to the signal to increase or decrease the production for one or more selected wells on a real time basis. The system for field wide reservoir management comprising a CPU for processing collected field wide reservoir data, generating a resultant desired field wide production/injection forecast and calculating a target production rate for one or more wells and one or more down hole production/injection control devices.
