“…When applied to VFM, for which the data is generated by a nonstationary process, both virtual and real concept drift will negatively influence the long-term predictive performance. A VFM performance that diminishes with time, has been documented in several publications (Grimstad et al, 2021;Hotvedt et al, 2022;Sandnes et al, 2021). In the following section, passive learning methods are discussed.…”

“…On the other hand, due to the slow dynamics of the reservoir, steady-state reservoir conditions for a certain time interval can often be assumed (Shippen, 2012). Furthermore, considering the inherent complex multiphase flow characteristics, which make it challenging to develop and solve nonstationary VFMs, steadystate VFMs are the most common approach in literature (Bikmukhametov and Jäschke, 2019), both for physics-based models (Shippen, 2012;Varyan et al, 2015) and machine learning (ML) models (AL-Qutami et al, 2017a,b,c, 2018Bikmukhametov and Jäschke, 2020;Grimstad et al, 2021). Nevertheless, studies show that steady-state VFM models should be updated or recalibrated in time to provide adequate long-term prediction accuracy (Sandnes et al, 2021;Hotvedt et al, 2022).…”

“…Neural network based approaches are prevalent and a common feature of earlier works is that wells are modeled individually from well tests or MPFM measurements. Several studies report impressive results, achieving average prediction errors below 5%, albeit with limited sample sizes [9,7,10].…”

“…The recent study in [10] applied Bayesian neural networks to data-driven VFM. The authors questioned if a robust data-driven method can be obtained by individually modeling wells from historical observations.…”
