The Effect of Flow From Perforations on Two-Phase Flow: Implications for Production Logging Academic Article uri icon

abstract

  • ABSTRACT The phenomenon of a dense phase (water) entering through perforations into a stream of a less dense phase (gas or oil) has been examined in a model wellbore. When water entered a gas stream, some of the water fell through the gas stream to occupy a portion of the wellbore below the perforations for all conditions tested and anomalous pressure behavior was observed in the region of the perforations. In the oil-water tests, all of the water was swept upwards by the oil only at the highest oil flow rate (5000 b/d) and lowest water flow rate (50 b/d) with the pipe vertical. The deleterious effect of dense phase fallback on production log interpretation is demonstrated.
