... on the corrosion resistance of carbon steel in different scenarios of pre-salt field production. The aim of the test program was to evaluate the influence of the produced water content (BSW), CO 2 partial pressure and oil characteristics on the carbon steel corrosion resistance. General corrosion analysis showed...

... on the internal surface of oil and gas pipelines plays an important role in protecting these pipelines from further corrosion. Whether precipitation of FeCO 3 is thermodynamically favorable is determined by a parameter called saturation of FeCO 3 , S FeCO 3 . In CO 2 corrosion, ferrous ions, coming from...

... mechanism. The present work was focused on developing a predictive tool for near-critical and supercritical CO 2 corrosion of mild steel. It incorporates changes in the water chemistry module due to update solubility and dissociation equations, changes in the electrochemical module due to the presence...

... ABSTRACT Pipeline transportation is a critical section in the context of carbon capture and storage (CCS) systems. Transported supercritical CO 2 (sc-CO 2 ) usually contains corrosive impurities, particular SO 2 , that can lead to exacerbated corrosion damage on pipeline integrity. However...

... ABSTRACT CO 2 corrosion mitigation is a challenge in the oil and gas industry. In order to decrease the severity of CO 2 corrosion of carbon steel pipelines and equipment, different mitigation practices are recommended. One such strategy is the application of surface active chemical...

... management. The present paper outlines corrosion threats associated with shale development, including acidizing, fracing, flowback, CO 2 and H 2 S in produced fluids and artificial lift. Usually little detailed information about corrosive exposure is available upfront. The production mode contributes...

... tubing suffers from serious corrosion induced by corrosive gas mixture including CO 2 , H 2 O and O 2 and so on, and even causes severe damage accidents. For example, several tubing fracture accidents occurred in a western Oilfield in China. It was mainly due to the significant thinning of local wall...

... ABSTRACT Graphene/epoxy composite coatings are prepared through dispersing graphene in waterborne epoxy coatings to investigate the CO 2 corrosion behavior in a high chloride environment. Scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS) are used to characterize...

... ABSTRACT The corrosion behavior of Ni-P coating in 3.5 wt% NaCl solution containing CO 2 and H 2 S was investigated using electrochemical methods and surface characterization techniques. The results show that CO 2 can promote the corrosion of Ni-P coating, and the corrosion resistance...

... ABSTRACT Recently, several localized corrosion and cracking failures happened to API 5CT Grade C110 tubing in high-density formate completion fluid at high temperature, because of the leakage of CO 2 and the mechanical damage on the tubing surface. In this paper, the hydrochemical simulation...

... ABSTRACT Stress corrosion cracking (SCC) of carbon steel may occur at near neutral pH in deoxygenated solutions with high bicarbonate concentration. Similar conditions are encountered in the annular space of flexible pipes when it is filled with CO 2 containing condensed water or seawater...

... ABSTRACT In High Pressure High Temperature “HPHT” wells (pressure above 690bar, temperature above 150°C) which contain CO 2 and H 2 S, operators need to select corrosive resistant materials. High strength grades are usually required to meet collapse and burst properties. The aim of the end...

... ABSTRACT Carbon steels are widely used in the oil and gas exploration and production service. However, these materials are prone to corrosion and cracking in CO 2 /H 2 S. The propensity to cracking increases when higher strength grades are employed. The use of corrosion resistant alloys...

...%. The test solution was aerated with CO 2 at ambient temperature and pressure before testing between 60 and 100 °C. Corrosion inhibitors performed at low temperature better than high temperature condition. Some of them showed poor inhibitor efficiency in case of pre-corrosion with high salinity. Several set...

... ABSTRACT Austenitic stainless steels are widely in use in oil & gas production environments providing effective protection for mitigation of general corrosion due to the presence of CO 2 in the produced fluids. However, there is little agreement on the service limits when exposed...
