  • France: JIP proposes to study plugging materials for well abandonments

    Institut Français du Pétrole

    Sooner or later, all wells at certain periods in their lives will be abandoned and require plugging. Inactive, improperly abandoned wells can become a significant threat to the environment by polluting groundwater quality and/or marine ecosystems. Oil companies’ onshore field experiences show that wells abandoned a few years ago sometimes exhibit leakage due to a lack of plugging set-up in wells. While it may be no problem to perform a remedial job in an onshore field (only expenditures could be critical), doing an offshore remedial job could have a dramatic cost effect. Consequently, abandonment of offshore wells must be considered carefully.
