Commingling
Commingled production is the flow of fluids, originating from two or more pools, in an unsegregated manner to a well measurement meter.
Production may be commingled down-hole in the wellbore or at the surface prior to metering.
Commingling may occur at any point in the life of a well, from initial design to a recompletion late in the life of a well. Commingling is a method to maximize the total recoverable hydrocarbons from a well. Commingling provides an opportunity to produce zones that may be individually uneconomic to produce, either initially or after having declined to marginal rates. Commingling may also help to lift liquids to the surface that would otherwise hinder production.
