Also, five different tubing pressure drop models were evaluated using extracted pseudo spontaneous potential PSP data from reservoir model to select the most accurate one for computing tubing performance relationship TPR data.

Both the inflow and outflow curves will be shifted if either of the fixed pressures in the system is changed, which ans occur when evaluating the effects of reservoir depletion or considering different separator conditions or wellhead pressures.
PIPESIM Nodal Analysis - Overview
In this study, a novel and integrated strategy is proposed to investigate the problem of low production rate of gas well in a supergiant gas condensate reservoir. In this strategy, the nodal analysis approach is applied for production optimization and performance assessment of a real inclined well. A multi-layered gas condensate reservoir model was constructed and simulated using actual reservoir rock and fluid properties. Effects of reservoir rock and fluid model simplification on inflow performance relationship IPR curves were investigated. Also, five different tubing pressure drop models were evaluated using extracted pseudo spontaneous potential PSP data from reservoir model to select the most accurate one for computing tubing performance relationship TPR data. Then, accuracy of nodal analysis in prediction of well operating point was investigated through comparing with reservoir simulator results.
Many two-phase flow correlations are based on a variable called superficial velocity. Although the hydrostatic oc elevatian component of the pressure gradicnt equation is not as important in pipeline tlow aS il is in wellnow calculations.

Nodal analysis is the standard technique used to evaluate the performance of integrated production systems. Two curves represent the capacities of the inflow and of the outflow, and the intersection of the two curves gives the solution operating point. Limitations of traditional nodal analysis include that. We propose a new nodal-analysis method that enables the study of transient production systems in a multiwell context and at different timesteps, with IPR models generated from a high-speed semianalytical reservoir simulator and outflow curves output from a steady-state pipeline simulator. The use of analytical reservoir simulation allows accurate, reliable modeling of the real inflow system, including deepwater and unconventional wells.
