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.

System and method for real time reservoir management

A LWD tool is disclosed for providing an image of the borehole during drilling or during removal of the tool from the borehole. The tool includes imaging transducers which are fired based upon either time or direction. Borehole reflections are processed to determine time-of-flight to give an indication of standoff with respect to each transducer from which the borehole geometry can be obtained. The reflections also are analyzed for other information, such as the amplitude of the reflected signal. The time-of-flight and amplitude values are encoded and stored in memory for retrieval later. In addition to the imaging transducers, the imaging assembly also includes depth transducers to obtain a micro measurement of depth downhole. The micro-depth measurements are stored and/or transmitted to the surface. In addition, a directional sensor and clock are provided downhole to correlate the firing of the transducers and the receipt of reflections. The micro-depth measurements and directional measurements preferably are used with one more image signals to check for the presence of bed boundaries intersecting the borehole. If a boundary is present, the imaging assembly applies a best fit sine wave to the image signal, from which dip angle .alpha. and dip direction are obtained. In the preferred embodiment, acoustic transducers are used as the imaging transducers, although electromagnetic transducers or other suitable transducers may be used.
