Method of Determining Queried Fluid Cuts Along a Tubular
First Claim
Patent Images
1. A method of determining queried fluid cuts along a tubular comprising:
- determining a first flow rate of a queried fluid produced from a plurality of zones along the tubular;
measuring a liquid flow rate produced by a selected zone of the plurality of zones;
ceasing production from the selected zone;
determining a second flow rate of the queried fluid produced from the plurality of zones along the tubular minus the selected zone; and
determining a queried fluid cut of the selected zone as a percentage of the liquid flow rate produced by the selected zone that a loss between the first flow rate of the queried fluid and the second flow rate of the queried fluid represents.

Abstract
A method of identifying a queried fluid cut along a tubular includes, determining a first flow rate of a queried fluid flowing through all open zones, determining a flow rate of liquid through a selected zone, and closing the selected zone, determining a second flow rate of the queried fluid flowing through all open zones, and attributing a queried fluid cut to the selected zone as a percentage that the difference between the first flow rate of the queried fluid and the second flow rate of the queried fluid is of the flow rate of liquid through the selected zone.

9. A method of determining queried fluid cuts along a tubular comprising:
-
determining liquid produced by all zones along the tubular; determining a queried fluid cut of the liquid produced by all of the zones; calculating a queried fluid produced by all of the zones; determining liquid produced by a selected zone along the tubular; closing the selected zone; determining liquid produced by all zones except the selected zone; determining a queried fluid cut of the liquid produced by all zones except the selected zone; calculating a queried fluid produced by all of the zones except the selected zone; and calculating the queried fluid cut for the selected zone as a difference in the queried fluid produced by all of the zones and the queried fluid produced by all of the zones except the selected zone and dividing by the liquid produced by the selected zone. - View Dependent Claims (10)

11. A method of identifying a queried fluid cut along a tubular, comprising:
-
determining a first flow rate of a queried fluid flowing through all open zones; determining a flow rate of liquid through a selected zone; closing the selected zone; determining a second flow rate of the queried fluid flowing through all open zones; and attributing a queried fluid cut to the selected zone as a percentage that the difference between the first flow rate of the queried fluid and the second flow rate of the queried fluid is of the flow rate of liquid through the selected zone.
