wellbore leakage ('In this report, we use the term "wellbore leakage" throughout, although many other more specifically defined terms have been used, such as gas migration, gas seepage, behind-the-casing leakage, surface casing vent flow, and so on. The term "wellbore leakage" is intended to be inclusive: it refers to all processes whereby fluids (oil, gas, brine, fracturing fluids. . . ) migrate from depth to the surface or near-surface during and after active operations.'  geofirma.com Aiduza); behind-the-casing leakage (Aiduza); behind-the-casing gas migration (Aiduza); behind-the-casing fluid migration (Aiduza) |

channeling (Remedial squeeze work on questionable cement jobs usually try the best ingenuity that can be mustered. Perhaps a more common problem is a channel job caused by an incomplete sheath around the pipe leaving a channel of completion fluid along the casing. This channel may be relatively short or run the complete height of cement. The problem is normally noted when the casing is perforated for production and the zone starts making completion fluid or water not identified with the zone of interest.
