Near surface pH measurements in aqueous CO2 corrosion
Electrochimica Acta, 2018Corrosion of carbon steels in a carbon dioxide (CO2) corrosive environment is an important issue and in some cases the steel surface can be covered by a protective corrosion product film. Research has shown that under certain conditions, once a truly protective film has precipitated on the steel surface, the corrosion rate can decrease by an order of ...

Modes of CO2-Corrosion Damage: Consequences for Corrosion Control Strategies
CORROSION 1996, 1996Abstract CO2-corrosion damage to C-steel and low-alloy steel may take various forms; the major types being pitting, grooving and uniform attack. In particular for tubular and pressure containing components, the significance of such damage on safety and reliability is dependent on its interaction with operational loads, and the potential ...

CO2 Corrosion in the Anadarko Basin
SPE Deep Drilling and Production Symposium, 1984Abstract Some high pressure, temperature and volume gas wells located in the Anadarko Basin area of Washita, Beckham, and Roger Mills counties of Oklahoma have demonstrated in several cases severe corrosion rates which has led to surface equipment and tubular failures.

CORROSION 2006, 2006
Abstract The literature has been reviewed with respect to information gained in the recent 20 years on CO2 corrosion of materials used in the oil and gas industry. The paper discusses the effect of materials-related, medium-related and interface-related parameters on general (uniform) and localized corrosion.

The Formation of Protective FeCO3 Corrosion Product Layers in CO2 Corrosion
CORROSION 1996, 1996Abstract Current models often over-predict CO2 corrosion rates for wet gas and oil transport systems. One of the main reasons for this is the fact that the formation of corrosion product scales is not properly taken into account. An evaluation of in-house and literature experiments has been carried out to develop an equation for iron ...

Corrosion Monitoring as a Means of Effecting Control of CO2 Corrosion
CORROSION 2001, 2001Abstract This paper deals with the use of on-line corrosion monitoring technology as a means of providing operators with real time information regarding the corrosion status of plant and pipeline. Correlation between instances of corrosion activity and processing/operational conditions can provide a valuable insight into the ...

Abstract Recent developments in understanding the mechanism of mild steel corrosion in the presence of carboxylic acids, carbon dioxide, and hydrogen sulfide has challenged the conventional views to corrosion in anoxic environments. Conventionally, the high corrosivity of such environments was associated with the direct reduction of ...

Corrosion Layer Breakdown and Localized Corrosion in CO2/H2S Environments
CORROSION 2012, 2012Abstract The results of flow loop corrosion experiments carried out with 5 bar CO2, 0.5 bar H2S, 50% MEG and 60°C are presented and discussed in detail, with focus on development of localized corrosion attacks and the composition and morphology of corrosion product layers.

CO2 / H2S Corrosion under Scale Forming Conditions
CORROSION 2005, 2005Abstract Three different mild steel coupons with two different surface areas were exposed to a CO2 saturated multiphase environment with a trace amount of hydrogen sulfide under supersaturated scale forming conditions designed to increase the probability of localized corrosion.
