Abstract
An apparatus for locating cement plugs and other devices downhole in a wellbore. A cement plug is moved downhole into a wellbore through a casing, and a transmitter sends a signal to a receiver. A processor engaged with the receiver identifies the elevation or location of the cement plug. Accurate placement of the cement plug eliminates problems associated with underplacement and overplacement of cement in a wellbore.
Claims18
A system for identifying the location of a body movable through a wellbore extending downwardly from the surface through subsurface geologic formations, comprising;
- a body moveable in the wellbore without the deployment of a wireline;
- a transmitter for transmitting a signal through the wellbore which identifies the location of said body within the wellbore;
- and
- a receiver for collecting said signal;
- and
- a processor engaged with said receiver for processing said signal and for identifying the location of said body within the wellbore from the signal transmitted through the wellbore by said transmitter.
