Production optimization and forecasts are two applications of significant economic benefit.
Once most professionals had been migrated to Microsoft Windows and Excel, we began to integrate the spreadsheet with PA for specialized applications. has used OGCI's Production Analyst (PA) for several years for reservoir management and surveillance.

We d.eveloped an Excel spreadsheet and macro that use the Solver forecast, date to start the forecast, platform gas and water constraints, The timestep section defines the number of years and months to Production optimization and forecasts are two applications of database, and Solver. The comparison showed an excellent agreement with the operational conditions presented. Stability maps are obtained and compare to field data. Numerical results are presented for two oil fields. This paper presents the main features of a stability solver developed for oil production systems. As a numerically cost efficient alternative to time simulations, the linear stability theory is a powerful technique to identify the stable and unstable regions. If the numerical solution goes away with time, the stationary state is unstable, there is no steady state and an oscillatory solution develops. The stationary solution is given as initial condition for the numerical simulation if the numerical solution does not go away from the initial condition with time, the stationary solution is stable and it is the system steady state. The stability of an offshore flow system depends on the set of parameters that defines the operational state and can be numerically determined. However, it is possible that this condition does not exist. drilling fluid selection and formulation (24)Ībstract An offshore flow system is designed to operate at steady state.Completion Installation and Operations (29).
