APRESENTAÇÃO
A integridade dos materiais em ambientes com presença de H2S e CO2 é uma das principais
preocupações na produção de petróleo na camada do Pré-Sal. Sempre atentas às necessidades do
setor de Óleo & Gás, a SURPLUS e a NACE SEÇÃO BRASIL trazem ao Rio de Janeiro os doutores
Chris Fowler e Srdjan Nesic, para a exclusiva SWEET & SOUR WEEK.
O evento será composto por dois cursos, um simpósio e um coquetel de encerramento.
O primeiro curso será o Materials For Use in H2S Environment and NACE MR0175 / ISO 15156-1
Discussion (Uso de Materiais em Ambientes com H2S e discussão da norma NACE MR0175 /
ISO15156-1), a ser realizado nos dias 16 e 17 de abril e ministrado pelo Dr. Chris Fowler, diretor
da Exova Group e Presidente da NACE International no período 2010/2011.
O segundo curso será o CO2 and H2S Corrosion in Multiphase Flow - Theoretical Aspects and
Applications (Corrosão pelo CO2 e H2S em Fluxos Multifásicos - Aspectos teóricos e Aplicações),
realizado nos dias 18 e 19 de abril e ministrado pelo Dr. Srdjan Nesic, professor da Universidade
de Ohio.
No dia 20 de abril será realizado um simpósio com a participação dos Drs. Chris Fowler e Srdjan
Nesic, além de representantes dos nossos principais centros de pesquisa, traçando um resumo
dos cursos e debatendo esse assunto tão importante para o setor. Após o simpósio será realizado

PROGRAMA
Materials For Use in H2S Environment and NACE MR0175 / ISO 15156-1 Discussion
(Uso de Materiais em Ambientes com H2S e Discussão da Norma NACE MR0175 / ISO15156-1)
DATA: 16 e 17 de abril de 2012
INÍCIO: 08:00 h / TÉRMINO: 17:00 h
PALESTRANTE: Dr. Christopher M. Fowler
• DAY 1
• INTRODUCTION TO MATERIALS
Consideration of alloy structures, particularly c-steel/low alloy steels, line steel
grades and how mechanical properties that influence field use may also contribute to
some types of corrosion related failure. Examples of manufacturing and fabrication
processes will be provided in the context of drawn tubing, plate and the
development of steel grades/line pipe steels, clad and lined steels, welded
constructions and weld overlay pipe.
• Materials Properties & Mechanical Testing
Mechanical properties of engineering metals and alloys (Ultimate Tensile
Strength (UTS), Yield Strength/Proof Stress, Hardness, Ductility, Toughness,
Creep) are shown to be determined by their chemical composition and
thermo-mechanical history (heat treatment and manufacturing processes).
Practical examples of brittle and ductile failure and typical test results from
Impact Tests (Charpy & Drop Weight Tear Test) and Hardness Testing will be
presented.
• QUALIFICATION OF MATERILAS FOR SERVICE IN ENVIRONMENTS WITH H 2S
• Definition of conditions of service in order to facilitate the selection of materials;
• Selection and pre-qualification of materials resistant to SSC / SCC in the presence of
sulfides.
• SOUR SERVICE FAILURE MECHANISMS IN LOW ALLOY STEELS
• Low alloy steels and carbon resistant to fracture and the use of cast iron
Effect of stress and fatigue cycles, hydrogen induced cracking (HIC), sulfide
stress corrosion cracking of low alloy steels will be discussed in the context
of brittle fracture, crack propagation, toughness, weldability, steel chemical
composition, thermo-mechanical treatments, testing.Cracking mechanisms
in acidic media services;
• Corrosion Resistant Alloys (CRAs)
Most CRAs have much greater corrosion resistance to general attack than
low alloy steels in all environments but are susceptible to damage by
localized corrosion and cracking mechanisms in some environments. Typical
issues associated with pitting, environmentally assisted cracking together
with the limitations on the uses of CRAs and problems that are encountered
will be discussed.
• DAY 2
• INTRODUCTION TO ISO 15156 & MRO175 AND MATERIALS SELECTION
An historical background to the development of specifications for sour service
will be presented. MR0175 was originally a document for controlling the
chemistry and heat treatment condition of wellhead control valves but has been
expanded to include drilling, gathering and flowline equipment plus field
processing facilities for sour hydrocarbon service. It typically recognises material
properties such as hardness, welding and microstructure affect cracking
behaviour hence maximum hardness (or yield strength) values are given for
most materials.
• ISO 15156, Part 1 - General Principles for Materials Selection
Requirements and recommendations for the selection of cracking-resistant
materials and qualification of metallic materials for service in H 2S-containing
environments, including sulfide stress cracking, stress corrosion cracking,
hydrogen-induced cracking and stepwise cracking, stress-oriented
hydrogen-induced cracking, soft zone cracking and galvanically induced
hydrogen stress cracking. The aim is to avoid costly corrosion damage to
equipment, but does not replace, the materials requirements given in the
appropriate design codes, standards or regulations.
• ISO 15156, Part 2 - Advances in Testing & SOHIC Issues
Part 2 is concerned only with cracking of resistant carbon and low-alloy
steels (the resistance of these steels to damage that may be caused by
sulfide stress-cracking (SSC) and the related phenomena of stress-oriented
hydrogen-induced cracking (SOHIC) and soft-zone cracking (SZC)), and the
use of cast irons. ISO 15156-2:2003 also addresses the resistance of these
steels to hydrogen-induced cracking (HIC) and its possible development into
stepwise cracking (SWC). Loss of material by general (mass loss) or localized
corrosion is not addressed.
• Materials Selection, CRAs & Testing for Sour Service
Part 3 of ISO 15156 gives requirements and recommendations for the
selection and qualification of CRAs (corrosion-resistant alloys) and other
alloys for service in equipment used in oil and natural gas production and
natural gas treatment plants in H2S-containing environments.
Tests are employed to ensure materials meet specifications, typical test
methods include: HPIC Tests: Coupon Specimens (NACE TM0284), SSCC
Tests: NACE Tests (TM0177), HPIC/SSCC/SOHIC Tests, Full Ring Test
developed to Determine the Susceptibility to Cracking of Linepipe Steels in
Sour Service, Full Scale Pressure Test.
CO2 and H2S Corrosion in Multiphase Flow - Theoretical Aspects and Applications
(Corrosão pelo CO2 e H2S em Fluxos Multifásicos - Aspectos teóricos e Aplicações)
DATA: 18 e 19 de abril de 2012
INÍCIO: 08:00 h / TÉRMINO: 17:00 h
PALESTRANTE: Dr. Srdjan Nesic
O CO2 e o H2S estão geralmente associados com a corrosão interna de instalações de
petróleo e gás feitas em aço carbono. O ataque corrosivo pode se tornar um problema
sério quando, na produção e transporte de petróleo e gás, quantidades significativas de
CO2, H2S e água estão presentes. Ambos, CO2 e H2S, são muito solúveis em água, onde
formam ácidos fracos, que podem atacar o aço. Apesar de milhares de artigos publicados
neste campo da corrosão, na literatura aberta, não se pode facilmente encontrar juntos
um quadro abrangente de corrosão pelo CO2 e H2S, uma vez que grande parte da
informação útil é dispersa e incompleta.
Recentemente, dois artigos foram publicados em um dos principais Manuais de Corrosão
(Uhlig e Shreir), os quais representam uma compilação do conhecimento atual sobre este
assunto, abrangendo os processos básicos, mecanismos e efeitos principais. No presente
curso, esses fundamentos serão cobertos, com um foco especial sobre os efeitos do
escoamento multifásico na corrosão interna pelo CO 2 e H2S em de dutos fabricados de
aço. As apresentações incluem tanto os fundamentos da corrosão como aplicações
relevantes para a indústria de petróleo e gás.
