A Comparison of the Pitting and Crevice Corrosion of Directional Drilling Alloys With Oilfield Production Alloys

Product Number: 51320-14432-SG

Author: Manuel Marya

Publication Date: 2020

$20.00

The pitting corrosion and crevice corrosion of oilfield production alloys (e.g., 13Cr/UNS S41000, 17-4PH/UNS S17400, 25Cr/UNS S32750, A286/UNS S66286, 718/UNS N07718) and proprietary austenitic stainless steels for directional drilling (PREN between ~20 to ~45) has been investigated. Specifically, series of electrochemical tests have been conducted to rank the alloys, establish simple correlations between electrochemical parameters, PRENmod, and 3-to-60-day immersion tests in 3.5% NaCl at ambient temperature. For all but one alloy, pitting was absent in stark contrast to crevices. Upon tracking populations and dimensional characteristics of crevices over time, trendlines comparing the susceptibility of the alloys towards crevice corrosion were established. Practical conclusions were reached, including the following: (1) 13Cr consistently developed crevices within days, (2) 17-4PH as well as all traditional directional drilling stainless steels developed crevices within one to five weeks, and, (3) neither 718, 25Cr, nor newer directional drilling alloys with both high nickel and high PRENmod showed any sign of crevices upon being tested up to 60 days. Through a variety of comparisons, this investigation also reveals useful technical directions for the development of new, economical, and fit-for-service Oil & Gas alloys for both production and drilling.

Martensitic Stainless Steel (SMSS) is widely used for downhole production tubing and liners in the Oil & Gas industry. Optimization of the tubular material chemistry, cleanliness and manufacturing route has delivered useful performance in H2S-containing environments (specifically SSC and stress corrosion cracking [SCC])3 resistance4,5,6. Some tubular accessories and most completion equipment require sizes not readily delivered by tubular product form. In these instances, bar stock material is a pragmatic choice.

An Evaluation of Well Completion Materials for Impure Carbon Dioxide Supercritical Streams in Hydrocarbon Production and Geological Carbon Sequestration

Product Number: MECC23-20034-SG

Author: Manuel Marya

Publication Date: 2023

$20.00

Carbon capture and storage (CCS) represents to traditional industrial emitters a critical transitional technology to globally manage greenhouse gas emission, meet the latest carbon net-zero ambitions, and continue the commercial use of fossil fuels. In CCS, anthropogenic CO2 is captured near emission, treated, compressed, transported (usually by steel pipelines), injected underground through casings, tubings, and completion equipment, and finally permanently stored into saline formations, aquifers, depleted (abandoned) reservoirs, or un-mineable coal seams. [1] Depending upon emitters, the injected CO2 is either near or in a dense state (i.e., indistinctly including a supercritical phase and potentially liquids) having various impurities.

An Exploratory Investigation of the Cracking Susceptibility of Three Corrosion Resistant Alloys under Thermal Cycles and Conditions Exceeding the Traditional NACE MR0175/ISO 15156 Recommendations

Product Number: 51324-20455-SG

Author: Manuel Marya

Publication Date: 2024

$40.00

The environmentally-assisted cracking (EAC) of three wrought corrosion-resistant alloys (CRAs) with a minimum yield strength of 110ksi (760MPa) was investigated between 70°F (21°C) and 450°F (232°C) through weekly thermal cycles totalizing 42 days. The thermal cycling was introduced to approximate service equipment conditions and gain additional confidence on the EAC-free limits of all three CRAs. Alloys 17-4PH, K-500, and 925 were selected and exposed to a 180,000-ppm NaCl brine (pH=2.75) in equilibrium with 1000 psi (68.95 bar) H2S, 1000 psi (68.95 bar) CO2, and 2500 psi (172.37 bar) CH4. All three CRAs were (a) acquired as per the NACE MR0175/ISO 1516 requirements (1), (b) tested as per NACE TM0177 Method C at 30-to-90% of the CRA minimum specified minimum yield strength (SMYS), and (c) also compared for their weight-loss corrosion and localized corrosion. The results show: (a) Alloy 17-4PH remains resistant to EAC below 45% of its SMYS, (b) Alloy K-500 resists cracking at an estimated 80% of its SMYS, but uniformly corrodes by sulfide conversion under film at a rate of 64 mpy (1.63 mm/yr.), and (c) Alloy 925 continues to be immune to EAC at 90% of its SMYS. Alloy 17-4PH also corroded at a rate of 22.8 mpy (0.58 mm/yr.) in comparison to only 0.6 mpy (15.2 mm/yr.) for Alloy 925, with no CRA showing experiencing crevice corrosion.
