Well production rate, injection rate and pressure data are measured in an existing reservoir using in situ real time measurement gauges. Production and injection rates are entered as input to a history match model in a data processing system. Measures of projected reservoir pressure with time are generated by running the updated history match model using a reservoir simulator. Actual reservoir data values obtained at a given date or time slice from reservoir production are compared with projected data obtained from the reservoir simulator for that same date or time slice. At each time slice, the real-time pressure values measured at the wellbore are converted into reservoir pressures through a well model. The real time reservoir pressure values and the projected reservoir pressure are then used to interpolate the reservoir pressure array over the entire three dimensions using a geostatistical modeling process.

Three-dimensional reservoir pressure determination using real time pressure data from downhole gauges

Systems and program product for creating and calibrating production and injection well models for a reservoir, are provided. An example of a system for creating and calibrating well models can include a well performance modeling computer and well performance modeling program product. The well performance modeling program product can include instructions that when executed by the well performance modeling computer cause the computer to perform operations including those for performing a comprehensive retrieval or gathering of required data components, feeding the gathered data into well performance software to thereby develop a model of the well, performing an initial calibration of the well model, performing a total system calibration on the well model, and performing a recalibration to fine tune the well model.
