The formation of scale deposits is a serious problem in many industrial applications including boiler cooling desalination geothermal oil and gas production. Scales typically encountered are sulfates carbonates and phosphates of barium strontium calcium and zinc. Over the years various additives have been developed to control precipitation of scale forming salts.This study is focused on the evaluation of natural hybrid and synthetic polymers containing a variety of different functional groups as inhibitors for strontium sulfate scale. Results reveal that various factors i.e. molecular weight type and amount of comonomer ionic charge of functional group hydrophobicity polymerization solvent etc. contribute to the performance of polymer as strontium sulfate scale inhibitors. Comparative performance of non-polymeric inhibitors will be presented.

This study investigates the contrasting characteristics of corrosion products/scales and corrosion behavior of X65 carbon steel when exposed to pure NaCl solutions compared to a complex brine solution at elevated temperatures and CO2 partial pressures. The focus of the experiments are directed towards the temperature range of 90-250°C and CO2 partial pressures of 1-20 bar. The corrosion scale morphology and chemistry are identified through a combination of Scanning Electron Microscopy (SEM) Focused Ion Beam (FIB) Energy-Dispersive X-Ray spectroscopy (EDX) X-Ray Diffraction (XRD) and Raman spectroscopy. The general and localized corrosion behavior is determined using gravimetric analysis and surface profilometry measurements respectively. The results indicate that Ca2+ and Mg2+ ions influence the formation of surface deposits significantly and this has a dramatic effect on their resistance to both general and localized corrosion. The surface characterisation methods employed indicated that the surface deposits comprised of iron carbonate (FeCO3) when the samples were exposed to pure NaCl solution below 150oC. However a complex mixture of Ca Mg and Fe-containing deposits were detected on the surface in complex brine solution below this temperature which are investigated in detail within this paper. Magnetite (Fe3O4) was shown to develop as an initial layer in both brines in conjunction with the other surface deposits beyond 150°C. The implications of the formation of such corrosion products and their relation to general and localized corrosion are discussed.

In the oil and gas industry internal corrosion of metallic components and piping is caused by the corrosive elements in the water associated with processed crude oil. Once established the corrosion characteristics of the produced / effluent water changes due to corresponding change in the fluid properties. By continuously monitoring the corrosion rates and type of corrosion attack on the standard corrosion coupons it is possible to get an indication of the corrosion trends within different water streams. The corrosion mitigation measures can then be selected and applied based on corrosion trends observed in the system. In this study internal corrosion monitoring data from sour and non-sour effluent water treatment plants and seawater treatment plant are evaluated with respect to dissolved H2S and bacterial activity especially the oilfield bacterial counts (General Aerobic General Anaerobic and Sulfate Reducing Bacteria). Distinct features have been observed on the corrosion coupons retrieved from sour and non-sour water systems and seawater service. Comparison of fluid corrosivity and bacterial activity was made in terms of corrosion rates and morphology found on the coupons retrieved from the sour / non-sour effluent water and sea water service and subsequent corrosion mitigation measures applied have also been presented here.

The stress corrosion cracking (SCC) behavior of Fe13Cr5Ni- and Fe17Cr5.5Ni-based alloys in HTHP CO2 environments was investigated through slow strain rate tests (SSRT) and electrochemical methods. The results show that a remarkable decrease in tensile strength and elongation to failure was observed when testing in CO2 environment as compared with air. Fe17Cr5.5Ni-based alloys possessed better SCC resistance than Fe13Cr5Ni-based alloys. The increase of Cr and Ni content tended to enhance the resistance to SCC and pitting corrosion. The SCC behaviors of Fe13Cr5Ni- and Fe17Cr5.5Ni-based alloys were closely associated with the repassivation capacity and the resistance to pitting corrosion.
