Abstract
The operational position of a moveable device is detected using an electromagnetic induction logging tool. The logging tool generates a baseline log of the moveable device in a non-actuated position, and a response log of the moveable device in an actuated position. The baseline and response logs are then compared in order to determine the operational position of the moveable device.
Claims22
A method for detecting a position of a downhole moveable device, the method comprising:
- emitting an electromagnetic (“EM”) field into a wellbore using a logging tool transmitter, thereby inducing current in a moveable device which produces secondary electromagnetic fields that emits from the moveable device;
- using a receiver of the logging tool to detect the secondary electromagnetic fields as response signals;
- and
- determining an operational position of the moveable device using the response signals, wherein determining the operational position comprises azimuthally determining the operational position of the moveable device.
