Development of abandonment fluid applied downhole while abandonment of offshore wells

Authors: A.N. Ivanov, A.L. Bushkovskiy, R.V. Karapetov, Hoang Quoc Khanh (JV Vietsovpetro), G.I. Anikeenko (Morneftegazprojekt ZAO)
First experience in activities relating to the abandonment of offshore wells in the oilfields operated and developed by Vietsovpetro JV has shown that abandonment fluids traditionally applied do not meet the Safety and Environment Regulations. This is because the applied solutions lose their technological properties during long-term abandonment and corrosivity increases due to biological degradation of reagents included in their composition. The paper discusses the development results of a new composition of the abandonment fluid applied downhole while abandonment of the offshore wells.
