Abstract

A fluid control system includes a fluid control device configured to be connected to at least one of two casing elements in a well, for controlling a fluid flow between a bore of the fluid control device and a zone located outside the casing elements; and a tracer material located within an inner chamber of a body of the fluid control device, the tracer material being uniquely associated with the fluid control device. The fluid control device is configured to release, when activated, the tracer material out of the inner chamber.

First claim

What is claimed is:

1. A method for controlling a fluid flow in a well, the method comprising:
providing a fluid control device comprising a body defining an inner chamber, a throughbore, an upper end, and a lower end;
connecting the upper end of the fluid control device to an upper casing element;
connecting the lower end of the fluid control device to a lower casing element;
lowering the fluid control device and the upper and lower casing elements into the well, such that an annulus is formed between the casing elements and the well;
actuating the fluid control device to establish fluid flow between the throughbore and the annulus and to open the inner chamber; and
releasing a tracer material from within the inner chamber of the fluid control device into the fluid flow,
wherein the tracer material is uniquely associated with the fluid control device.

2. The method of claim 1 , wherein the inner chamber is defined only by an inner sleeve and a body of the fluid control device.

3. The method of claim 1 , wherein the tracer material is located in its entirety within the inner sleeve.
