51316-7270-Electrochemical Corrosion Behavior of Niobium Alloys as Metallic Bio-Implants

Product Number: 51316-7270-SG
ISBN: 7270 2016 CP
Author: Wei Wang
Publication Date: 2016
$20.00

Mechanical properties and microstructure of Nb-Ta-Re, Nb-Re, Nb-Pd, and Nb-Pt alloys were studied by nano-indentation measurements and X-ray diffraction. Corrosion behavior was compared by electrochemical methods, including open circuit potential measurement, potentiodynamic, and electrochemical impedance spectroscopy.

Development of High Strength grade and Cost Effective Super Martensitic Stainless Steel Solution for high CO2/H2S environment

Product Number: 51320-14715-SG
Author: Cécile Millet, Martien Deffo , Harold Evin, Guillaume Néel
Publication Date: 2020

Super martensitic stainless steel (13Cr-5Ni-2Mo) provides high strength and CO2 resistance. It can be used at high temperature up to 180°C/356°F in high chloride environment. When the well temperature is above 180°C/356°F, Duplex grades 22-5-3 or Super Duplex 25-7-4 grades are commonly selected as per API 5CRA standard.
A new proprietary grade chemistry has been developed to provide improved strength up to 125ksi and higher pitting resistance while maintaining a tempered martensitic microstructure with low delta ferrite content and no detrimental phases or precipitates. Improvement of pitting resistance has been assessed through cyclic polarization curves. Higher sulfide stress cracking (SSC) and stress corrosion cracking (SCC) were assessed through NACE(1) TM 0177 method A 1 at ambient and high temperature. X-ray Photoelectron Spectroscopy (XPS) characterizations provide deep knowledge about passive film compositions underlining the beneficial effect of higher Mo within the grade.
This paper presents the benefit of the improved chemistry on sweet corrosion and sulfide stress cracking in severe downhole environment. It summarizes the effect of different parameters in both production and shut-in conditions to be considered to select cost effective material.

Thiols as Volatile Corrosion Inhibitors for Top of the Line Corrosion

Product Number: 51317--9096-SG
ISBN: 9096 2017 CP
Author: Zineb Belarbi
Publication Date: 2017
$20.00

The effectiveness of hexanethiol, decanethiol and 11-mercaptoundecanoic acid for CO2 corrosion inhibition of carbon steel exposed to top of the line conditions has been investigated. Weight loss measurements were used to measure the corrosion rate.
