... in these treatments. However, these acids can cause formation damage by forming stable emulsions and sludge upon contact with formation crude if the treatment and/or stimulation fluid are not designed carefully. It is well reported that acid in contact with crude oil can destabilize asphaltenes either by neutralizing...

... Oil-based sludge formation during oil well acidizing is well addressed in literature ( Al-Taq et al, 2015 , Abdollahi et al. 2014 , Almubarak et al. 2020 ) Abdollahi et al (2014) found that acid-induced oil-based sludge increased as the acid strength was increased and similarly was observed...

... Abstract Following Tantawan field suspension of production, considerable volume of contaminated crude (high level of mercury and arsenic content) remains on board in Tantawan FPSO. These volumes are deemed as waste hydrocarbon sludge that hold no commercial value and must be urgently removed...

... Treatment and management of oil-impacted wastes (e.g. tank bottoms, clarifier or pit sludge, oil-impacted soils) poses significant technical and financial challenges at exploration and production (E&P) facilities. Often these materials are distant from waste disposal or treatment...
