Abstract
Various chemical reagents have treated seawater before the latter being injected into petroleum bearing formations through steel pipelines. Separate and mutual influence of 5 reagents (oxygen scavenger, coagulator, biocide, filter aid and antifoam) on steel corrosion behavior in seawater has been studied by weightloss methods. Oxygen scavenger showed good steel corrosion inhibition. However, its inhibition efficiency was badly affected by other additives, particularly in the presence of ferric sulphate as coagulator. Based on the obtained results some aspects in steel corrosion kinetics have been proposed for the seawater injection system.
