CHARACTERISTICS OF CORROSION SCALES ON STEELS IN A CO2-SATURATED NACL BRINE

Abstract A consequence of corrosion of steel in the presence of oxygen-free carbon dioxide and a water phase is the formation of an iron carbonate (FeCO3 corrosion scale. This scale provides some p...

EFFECTS OF FLOW VELOCITY ON INHIBITORS USED IN OIL AND GAS PRODUCTION

The paper describes an experimental facility designed to study velocity effects on corrosion inhibitor films. These studies have application to corrosion problems found in offshore oil and gas production equipment. Initial results concerning velocity effects on the performance of oilfield corrosion inhibitors are presented. The experimental facility consists of a flow loop designed to produce two-phase flow conditions for a variety of gas-liquid ratios at velocities in the test section up to 150fps. Data are presented showing the erosive effects of high flow velocity on inhibitor film performance. The effect of surface roughness on corrosion rates for two inhibitors is examined.
