Laboratory and field trials have demonstrated the successful use of concentrated corrosion inhibitors for chemical treatments. The concentrated applications are most useful in remote areas such as the jungle when performance is also related to handling, distribution, and cost reduction. These products are the concentrates of treating chemicals typically prepared as 25% to 50% dilutions in solvents. The concentrated products are used in the same injection points as the less active corrosion inhibitors and demulsifiers. Currently, the concentrated field applications are on location in 80% of the chemical treatment points. The corrosion inhibitors are injected at lower treatment concentrations as the regular products with no loss of performance. Keywords: corrosion inhibitors, concentrate chemicals, solvent, distribution, corrosion process. HTHP, RCE, polarization.

A forty foot well annulus simulator is used to determine the flow and fate of the applied chemical inhibitors for typical backside batch and flush application in a packerless completion. The delivery depends upon both chemical parameters such as density, viscosity, and surface tension as well as flush parameters including volume and rate.

Results of inhibitor performance at slug flow in a 101.6 mm inner diameter horizontal pipeline. Electrochemical Impedance Spectroscopy (EIS) and scanning electrom microscope (SEM) techniques are used to reveal that the strong bubble impact, high shear stress and turbulent intensity are the reasons for a poor performance of inhibitor.

02274 EFFECTIVENESS OF CORROSION INHIBITORS IN RETARDING PROPAGATION OF LOCALISED CORROSION

In many service applications excursions in solution chemistry, temporary loss of inhibitor, or transient increases in temperature may give rise to localised corrosion. To test the return of inhibition when the loss is remedied, the use of an artificial pit has been investigated using simulations of cooling water and of of oil production formation water.
