Corrosion tests in laboratories to investigate the corrosion rate and to qualify production chemicals are only valid and applicable if the conditions and chemical environment (pressure, temperature, wall shear, pH, CO2 and H2S partial pressures, electrolyte composition) are representative of the field conditions. Representative sulfide concentrations are sometimes achieved by adding a sulfide salt (e.g., Na2S.9H2O) to minimize health and safety risks associated with the direct use of H2S gas. The current study compares the corrosion of carbon steel in nominally comparable sour conditions generated either using H2S gas or sodium sulfide salt. Tests were performed at 90 °C/101.3 kPa and at 120 °C/20 MPa using H2S partial pressures (pH2S) of 0.1 kPa (0.1 mol% H2S at 1.013 bar), 0.2 kPa (0.2 mol% at 1.013 bar) and 40 kPa (0.2 mol% at 200 bar). The corrosion rate was monitored by linear polarization resistance at ambient pressure and by weight loss measurement at higher pressure. Surface morphology of the coupons was assessed by optical microscopy, scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDX). Ambient pressure linear polarization resistance (LPR) measurements with low H2S partial pressures showed comparable corrosion rates obtained using either H2S gas or sodium sulfide. In contrast, in the tests at higher pressure, significantly lower corrosion rates were measured when using H2S gas than with sodium sulfide. Moreover, microscopy showed pitting when sulfide was introduced as the salt, but pitting was absent when the sour environment was generated by H2S gas. Supportive work on other systems has shown that small changes in in situ conditions, particularly at elevated pressure (high H2S partial pressure), have a significant impact on the recorded corrosion rates, and therefore the ability to accurately match the environment within the test cell between generating the in situ sulfide via salt addition versus H2S gas is likely to be the root cause. In summary, therefore at high H2S partial pressure, particularly where the corrosion becomes dominated by sour corrosion, such issues related to the test methodology, and the ability to achieve representative in situ conditions, may lead to disqualification of corrosion inhibitor candidates that otherwise could have achieved the pass criteria were testing performed using H2S gas.

CorrCompilation: Oil Production Chemicals, Volume 3

Product Number: 37653-e
ISBN: 978-1-57590-398-9
Author: Edited by Joseph Itodo Emmanuel
Publication Date: 2019
$130.00

The “CorrCompilation: Oilfield Production Chemicals” series covers production, selection, performance evaluation, application, monitoring, and optimization of oilfield chemicals. The oilfield chemicals presented are corrosion inhibitors, biocides, scale inhibitors, and drag reducers. The editor, Joseph Itodo Emmanuel, believes it is a “must-have reference book” for corrosion engineers in the field, technicians, and field operation supervisors due to its broad spectrum.

He suggests the compilation could be used for a university-level engineering or scientific course on oilfield chemicals or tailored training to enhance the technical knowledge of field personnel on oilfield chemical application and management.

Since this CorrCompilation series consists of 90 NACE technical papers or articles, it is published in three volumes. 

Volume 1: Development and Selection

Volume 2: Performance Evaluation and Application

Volume 3: Monitoring and Optimization

Each volume contains current research findings, field treatment practices, best practices, and scientific and engineering concepts.

Evaluation Of Dead Leg Piping with Internal Corrosion at A Salt Dome Natural Gas Storage Facility

Product Number: 51323-19041-SG
Author: Leslie A. Ward, Len J. Krissa, Garry Matocha, Thomas Pickthall
Publication Date: 2023
$20.00

The essence of this paper is to talk about internal corrosion found in deadleg piping at the Enbridge Gas Transmission, & Midstream (GTM) Egan Hub Partners Storage Facility and especially how the corrosion was evaluated after the deadlegs were removed. The salt dome cavern storage facility is in south central Louisiana. The internal corrosion was found in the piping that comes from the storage caverns and goes through pressure reduction stations and then through dehydrations systems.

Fitness-for-Purpose Research of OCTG for Underground Gas Storage Applications in H2/CO2 Environments

Product Number: 51320-14698-SG

In China, some underground gas storages (UGS) would be built to reserve the gaseous coal gas (CO, H2, CO2, H2O, etc.). Gaseous hydrogen induced hydrogen embrittlement (HE) and CO2 corrosion could possess great threat to the safety of OCTG in UGS. Fitness-for-purpose research of OCTG materials is urgently expected to screen out the suitable material for tubing application in UGS.
HE resistance and CO2 corrosion of OCTG materials (C110, 3Cr-90S, 13Cr-110 and 13Cr-110S) were investigated by slow strain rate testing and weight loss tests in UGS environments containing CO2 and H2. SSRT results show that both elongation ratio and reduction in area ratio of C110, 13Cr-110 and 13Cr-110S were more than 80%, except for 3Cr-90S. In addition, 3Cr-90S and 13Cr-110 tested in H2/CO2 environments possessed embrittled regions and secondary cracks, respectively. Weight loss test results show that C110 and 3Cr-90S exhibited high corrosion rates, which were classified as severe corrosion followed by qualitative categorization of corrosion rates for oil production systems in NACE RP0775. For stainless steels (13Cr-110 and 13Cr-110S), the corrosion rates were very low (low corrosion). Combined with the above results, 13Cr-110S could be the suitable OCTG material for UGS containing gaseous coal gas.
