Abstract
Methods and systems for estimating multi-phase fluid rates in a subterranean well (). Stored and measured static () and transient () well conditions are used to model well conditions for comparison against additional transient data () relating to temperature, pressure, and flow. Multi-phase fluid rates are estimated by iteratively comparing well conditions with the model () for the well (). Multi-phase fluid flow estimates may be obtained for the various liquid and gaseous fluids in the well () at multiple well locations ().
