... anomalies can be detected (not only integrity-related) which creates additional value for operations. This paper describes practical cases with explanations of well behavior and gives examples of the early detection of well integrity issues. algorithm anomaly pattern recognition modeling...

... have provided an ability to even attempt the modelling of hydrate blockage formation in pipelines, the next generation of these predictive tools must directly integrate hydrate-specific formation and transportability models within a transient multiphase flow algorithm. In this manuscript, we present...

....) are solved simultaneously using an iterative method. The flow rates, pressures and temperatures along the system are then computed. This process is typically referred to as piping network solving . Some solution methods and algorithms employed for piping network solving are described in detail in (3) and (4...

... of gas and liquid operation parameters we are looking for. The algorithm for signal processing and analysis results in a good estimation of the liquid and the gas flow rates. In a certain range of GVF (gas volume fraction) the estimation results in flow rate measurement at commercially accepted...

... of fluid mechanics are introduced to the pattern recognition system. This latter uses a dedicated multilayer neural network algorithm to overcome the nonlinearity and uncertainties of the sensors. The system, which is compact and easily portable, has been implemented and extensively tested on a Lab-scale...

... instability appears. Experiments have been performed on a two-phase test facility to verify the numerical results. Traditionally unstable flow is suppressed by choking at the wellhead, resulting in increased backpressure, hence production deferment. OLGA simulations show that the Shell Smart Choke algorithm...
