  • Multi-well time-lapse nodal analysis of transient production systems
    Patent number: 8788252
    Abstract: A method, apparatus and program product utilize an analytical reservoir simulator to perform inflow simulation for a node during nodal analysis in a multi-well petroleum production system. By doing so, time-lapse nodal analysis may be performed of a transient production system in a multi-well context, often taking into account production history and the transient behavior of a reservoir system. Moreover, in some instances, an interference effect from different wells in a multi-well production system may be considered, and in some instances nodal analysis may be performed simultaneously for multiple wells. Multi-layer nodal analysis may also be performed in some instances to account for the pressure loss in a wellbore between multiple layers.
