Flowmeters

Applications

Tools that measure flow rate or trace where fluids have gone have applications
in both producing and injecting wells. Specifically, these types of tools may be
used for:

1. Production profiles
2. Injection profiles
3. Finding casing and tubing leaks
4. Gauging the effectiveness of well treatments

The tools available for making the appropriate measurements are:

Packer flowmeters (including basket type)
Continuous flowmeters (spinners)
Full-bore flowmeters
Oxygen activation (using a pulsed neutron tool)
Radioactive tracers (gamma ray)
Temperature gauging devices (both conventional thermometers and fiber optics)

Each tool has its particular merits for certain well conditions and ranges of flow
rates. Table 5.1 summarizes each tool's applicability.
