Effect of H2S and CO2 on Cement/Casing alloy interface corrosion integrity for cold climate oil and gas well applications
(The Electrochemical Society, 2016)
A study has been carried out to investigate sweet and sour corrosion at the cement-casing interface for offshore oil and gaswells in cold climate. The test solution chemistry was determined by sampling pore water from ...
The effect of polypyrrole and nickel + polypyrrole coatings on corrosion behaviour AISI 304 stainless steel
(Pleiades Publishing, Ltd, 2015)
Polypyrrole (PPy) and nickel + PPy (Ni + PPy) coatings have been occured on AISI 304 stainless steel (304 SS) surface by cyclic voltammetry technique in aqueous oxalic acid solutions and as the supporting electrolytes was ...
Corrosion of 13Cr steel at the Cement/Casing interface in CO2/H2S environments at 4, 85 and 200 °C
(Nace International, 2018)
A study was carried out to investigate corrosion at the cement/casing interface for 13Cr casing steel. Cement simulated pore solution (CSPS) was developed by exposing cement pieces to 5% NaCl at 100 °C and 10 MPa in ...
Effects of CO2 and H2S on corrosion of martensitic steels in NaCl(aq) at low temperature
(Nace International, 2016)
Corrosion studies were conducted for martensitic carbon steels in brine solutions at 4 °C and 10 MPa (1450 psi), which simulated the subsurface environments encountered in Arctic drilling. Three environments with a 5 % wt. ...
Corrosion behavior of boro-tempered ductile iron
(Springer Link, May 2010)
In this study, the effect of boro-tempering heat treatment on the microstructure and corrosion behavior of unalloyed ductile iron was investigated. The corrosion characteristics of ductile iron have been determined by ...
The effect of alcohol on the passivation of Al alloys in 1 N H 2 SO 4 solution
(Pleiades Publishing, Ltd, 2010)
In this study, the influence of different alcohol on the passivation of aluminium alloys have been investigated by using current potential curves. Experimental results show that the addition of alcohol in H2SO4 solution ...
Corrosion inhibition of st37 steel in geothermal fluid by quercus robur and pomegranate peels extracts
(Pleiades Publishing, Ltd, 2015)
Plant extracts have become important as an environmentally acceptable, readily available and renewable source of wide range of inhibitors. Tannins, a class of natural, non toxic and biodegradable polyphenolic compounds, ...
Hydroxyapatite (HAP) coating with biomimetic method abstract
(Afyon Kocatepe Üniversitesi, 2009)
Biomimetik yöntemle hidroksiapatit (HAP) kaplama en gelecek vaat eden tekniklerden birisidir. Bu çalışmada, üç farklı ön yüzey işlemi (HNO3, anodik polarizasyon, 5 N NaOH-1 N HCl (BA)) altlıkların (Ti ve Ti6Al4V) yüzey ...
Electrochemical determination of bisphenol a with pencil graphite electrodes modified with Co(II), Ni(II), Cu(II) and Fe(II) phthalocyaninetetrasulfonates
(The Japan Society for Analytical Chemistry, 2016)
Pencil graphite electrodes modified with Co(II), Ni(II), Cu(II) and Fe(II) metallophthalocyaninetetrasulfonates (MePcTSs) were investigated for electrochemical determination of bisphenol A (BPA). Electrochemical performances ...
Corrosion behavior of ultra-high strength drilling steel in alkaline brines containing hydrogen sulfide at high temperature
(Nace International, 2016)
In-situ electrochemical measurements were used to study the sour corrosion of ultra-high strength low alloy carbon steel (UHSLA) in alkaline brines at 200 °C. The solutions were buffered with NaHCO3 / Na2CO3 / NaOH to pH ...
