Plural sensors are deployed into a well, and measurement data regarding at least one property of the well is received from the sensors. Based on the measurement data, a first of the plural sensors that measures the at least one property in a region having an annular fluid flow is identified, and a second of the plural sensors that measures the at least one property in a region outside the region having the annular fluid flow is identified. Based on the identifying, the measurement data from selected one or more of the plural sensors is used to produce a target output.

1. A method comprising: deploying plural sensors into a well;receiving measurement data regarding at least one property of the well from the sensors;identifying, based on the measurement data, a first of the plural sensors that measures the at least one property in a region having annular fluid flow
1. A method comprising: deploying plural sensors into a well;receiving measurement data regarding at least one property of the well from the sensors;identifying, based on the measurement data, a first of the plural sensors that measures the at least one property in a region having annular fluid flow, and a second of the plural sensors that measures the at least one property in a region outside the region having the annular fluid flow; andbased on the identifying, using the measurement data from a selected one or more of the plural sensors to produce a target output. 2. The method of claim 1, wherein producing the target output comprises producing a model to predict the at least one property. 3. The method of claim 2, wherein producing the model comprises producing the model having predicted values of the at least one property matched to the measurement data from the selected one or more of the plural sensors. 4. The method of claim 1, wherein producing the target output comprises generating a flow profile along the well based on the measurement data of the selected one or more of the plural sensors. 5. The method of claim 1, wherein producing the target output comprises estimating properties of a reservoir surrounding the well. 6. The method of claim 1, wherein deploying the plural sensors comprises deploying a spoolable sensor array into the well. 7. The method of claim 1, wherein the identifying is based on comparing a response of each of the plural sensors to sensor profiles. 8. The method of claim 7, wherein the identifying further comprises: determining, from a first response profile of the measurement data from the first sensor, that the first sensor is being subjected to direct impingement by the annular fluid flow; anddetermining, from a second response profile of the measurement data from the second sensor, that the second sensor is measuring the at least one property due to axial flow of fluid in the well. 9. The method of claim 1, wherein the selected one or more of the multiple sensors include the second sensor but not the first sensor. 10. The method of claim 1, wherein the identifying is performed by a controller having a processor. 11. A system comprising: a plurality of sensors for deployment in a well;a controller configured to: receive measurement data from the plurality of sensors;based on analyzing the measurement data, identify a first of the sensors that is subjected to annular fluid flow and a second of the sensors that is not subjected to annular fluid flow;based on the identifying, select one or more of the sensors; anduse the measurement data from the selected one or more of the sensors to produce a target output. 12. The system of claim 11, wherein the target output includes a model to predict a property of the well. 13. The system of claim 12, wherein the controller is configured to adjust at least one parameter of the model based on the measurement data of the selected one or more sensors. 14. The system of claim 13, wherein the selected one or more sensors include the second sensor but not the first sensor. 15. The system of claim 11, wherein the target output includes one or more of a flow profile in the well and a property of a reservoir surrounding the well. 16. The system of claim 11, wherein the controller is configured to further identify another first sensor that is subjected to annular fluid flow and another second sensor that is not subjected to annular fluid flow. 17. The system of claim 11, further comprising: a further plurality of sensors for deployment in a second well;wherein the controller is configured to further: receive measurement data from the further plurality of sensors;based on analyzing the measurement data from the further plurality of sensors, identify a first of the further plurality of sensors that is subjected to annular fluid flow and a second of the further plurality of sensors that is not subjected to annular fluid flow;based on the identifying, select one or more of the sensors further plurality of; anduse the measurement data from the selected one or more of the further plurality of sensors to produce another target output. 18. The system of claim 11, wherein the plurality of sensors is part of a spoolable array of sensors. 19. An article comprising at least one non-transitory computer-readable storage medium that upon execution cause a system having a processor to: receive measurement data regarding at least one property of a well from plural sensors deployed in the well;identify, based on the measurement data, a first of the plural sensors that measures the at least one property in a region having annular fluid flow, and a second of the plural sensors that measures the at least one property in a region outside the region having the annular fluid flow; andbased on the identifying, use the measurement data from a selected one or more of the plural sensors to produce a target output. 20. The article of claim 19, wherein producing the target output comprises producing a model to predict the at least one property. 21. The article of claim 19, wherein producing the target output comprises producing one or more of a flow profile in the well and a property of a reservoir surrounding the well.
