Multi-well time-lapse nodal analysis of transient production systems

摘要

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.

1. A method of performing nodal analysis for a multi-well petroleum production system comprising a plurality of wells coupled to a reservoir, the method comprising:
for a node in the multi-well petroleum production system:
simulating inflow for the node by performing reservoir simulation using a computer-implemented analytical reservoir simulator that predicts a flow of fluid through a porous media, wherein the reservoir simulation performed by the analytical reservoir simulator simulates inflow by simulating a transient behavior of the multi-well petroleum production system based at least in part on a production history for the multi-well petroleum production system; and determining an operating point for the node based upon the reservoir simulation.
