Abstract:
1. An instrumented tubing for determining a contribution of a given zone to fluid production of a reservoir, the instrumented tubing comprising: a tube having an open end, a closed end, a circumferential sidewall extending between the open end and the closed end, and a port defined in the circumferential sidewall, the tube configured to be laterally coupled to a production tubing in a parallel manner at the port with the port being adjacent a corresponding opening in the production tubing, putting in fluid communication the tube with the production tubing, the open end collecting a fluid flowing from the given zone and the port letting the collected fluid flow into the production tubing; a sensor positioned within the tube for measuring a parameter of the collected fluid, wherein the sensor is connected to an electronic unit for determining the contribution of the given zone to the fluid production of the reservoir based on said measured parameter; and a control valve disposed at the closed end of the tube and extending downwardly toward the port to adjust the flow of fluid flowing through the tube towards the production tubing.
