There are numerous techniques related to the regeneration of wells with respect to pollution like corrosion, silting, clogging, etc. . What options do exist in order to regenerate groundwater wells which are polluted with oil phases?
Well,
Convert oil to the colloidal phase using compressed hot water vapor and CO2 gas and exploited by the airlift system.

Non-aqueous phase liquids (NAPLs) in pumped groundwater are highly variable, challenging the selection of above-ground treatment strategies in pump-and-treat system. Adjustable systems with multiple treatment units are urgently required. In the present study, a mobile, modular and rapidly-acting treatment system was developed to treat groundwater contaminated by NAPLs at a chemical industrial site. The system integrated four units of coagulation sedimentation, air flotation, air stripping and chemical oxidation.

Tank you all for answering. Indeed, it is very challenging. I forgot to mention that the wells were built with PVC well screens. In this case, Bayan Hussien I guess CO2 injection is not an effective method?
Well,
Maybe, but it is used as a drive base in the low-pressure oil field to gather the oil that existed within the pores of oil-bearing horizons and push it to the production borehole.

Dear Dr Leonard Krebbers
For mechanically dug wells, the well and filtered casing is cleaned with a brush, air blowing or sudden bursting techniques also used for well development.

Thank you for sharing this information, Abderrahmane Noui. Are you also experienced in regenerating oil-contaminated groundwater wells using these methods?
Best regards
