... excellent lubricity performance while reducing corrosion in drill pipes. The oil-based mud whose coefficient of friction (CoF) is usually less than 0.1 ( Ismail et al., 2015 ) is commonly favorable in improving lubricity performance of drilling fluids and reducing corrosion rate in drilling pipes compared...

.... Nyborg R. published a paper about the existinh prediction models in 2010. Currently, what is predicted is not an accurate corrosion rate but a "severity level". Even though a good severity prediction is sufficient to make the choice between carbon steel and a corrosion resistant alloy or need...

... is lower than the field application at 71 oC and the latter significantly higher. To this end, the expected corrosivity had to be extrapolated for the Golden Eagle conditions making relevant assumptions. Numerically, the measured corrosion rate for carbon steel ranged between 0.11 – 0.13 mm/y at 55 oC...

... injection systems by analysing theoretical polarisation curves and results from published works with different approaches. Corrosion models consider mass-transfer controlled diffusion of oxygen to predict the maximum steel corrosion rate, which depends on the oxygen limiting current, which in turn...

An autoclave setup is proposed and validated to simultaneously test different conditions. Corrosion rates are extrapolated to compute service life of the materials and guide material selection...

... a corrosive environment in the confined space between the sheaths. A large steel surface to water volume ratio leads to rapid accumulation of dissolved corrosion products and precipitation of protective iron carbonate (FeCO 3 ) films. Low corrosion rates (<0.01 mm/y) are usually experienced in the field...

For comparison, actual corrosion rates of dissimilar material couples were measured gravimetrically. The results exhibit the influences of temperature, bicarbonate and acetic acid on the electrode potential...

... in recirculating flow circuits, can generate corrosion rates of up to 65 mpy after four weeks of growth. The samples taken for the enrichment of corroding cultures came from a low tide anoxic sediment sample (black sand). In this presentation and paper, this method and its application to the benchmarking of field...

.... The flow was switched to the next loop immediately prior to administration of the next dose. The coupon was removed from the used section for corrosion rate determination. The loop was then drained, purged with nitrogen and then prepared for the next dose. The loop was injected with inhibitor using...

... and corrosion rate with various partial pressures. With increasing partial pressure of CO 2, the corrosion rate increases steeply as temperature increases. However, after the formation of an iron carbonate layer, the corrosion rate declines because the passivation properties of the iron carbonate layer...

... The NORSOK M-506 software was used to estimate the uninhibited corrosion rates and shear stress as a function of the flow conditions, pressure and temperature of the SFA pipeline. The code takes into account the effect of the FeCO 3 protective film at high temperatures (and high pH) more...

To meet the challenge of testing accelerated corrosion rates, various laboratory methods have been developed to study the effects of increasing shear on corrosion. Common...

... and 10ppm of inhibitors, the average corrosion rate decreases from 0.22mm/yr to 0.11mm/yr and from 0.21mm/yr to 0.05mm/yr with 50ppm of both inhibitors. At 80°C, the corrosion rate decreased from 0.20mm/yr to 0.07mm/yr with 10ppm of inhibitors, and from 0.19mm/yr to 0.03mm/yr with 50ppm of inhibitors...

Abstract Published corrosion studies have demonstrated the formation of a passive layer and assessed corrosion rate in a NaCl matrix fluid. However, a critical issue for corrosion laboratory tests...

This result is consistent with volatile CI being present in the initial CI formulation, which was then collected in the condensed vapour obtained from the distillation. In contrast, the distillate sample of TOL...
