This paper analyzed the HSLA pipeline steel’s stress corrosion behavior and mechanism which tested in the saturated solution of H2S. The steel’s SSCC susceptibility was determined by constant load tensile according to NACE TM-0177 standard. Used SEM observed the fracture, and then the steel’s corrosion rate and short-term corrosion behavior were analyzed by electrochemical polarization curves in saturated solution of H2S in the environment A. The results show that the steel has a large SSCC susceptibility and a high corrosion rate. What’s more, corrosion rate increases with the increase of immersion time. The results also show that the crack fracture of the steel is caused by anodic dissolution and the hydrogen which penetrates into the steel can increase the anodic dissolution.

Sour Service

The scarcity of oil and gas resources made High Pressure and High Temperature (HPHT) reservoir attractive to be developed. The sour service environment gives an additional factor in material selection for HPHT reservoir. Austenitic 28 Cr and super duplex stainless steel 2507 (SS 2507) are proposed to be a potential materials candidate for such conditions. C-ring tests were performed to investigate their corrosion behavior, specifically sulfide stress cracking (SSC) and sulfide stress cracking susceptibility. The C-ring tests were done under 2.55 % H2S (31.48 psia) and 50 % CO2 (617.25 psia). The testing was done in static environment conditions. Regardless of good SSC resistance for both materials, different pitting resistance is seen in both materials. The pitting resistance did not follow the general Pitting Resistance Equivalent Number (PREN), since SS 2507 super duplex (PREN > 40) has more pitting density than 28 Cr austenitic stainless steel (PREN < 40). SS 2507 super duplex pit shape tends to be larger but shallower than 28 Cr austenitic stainless steel. 28 Cr austenitic stainless steel has a smaller pit density, yet deeper and isolated.

Minimum Yield

Abstract In recent years the application of high strength carbon steel with 125ksi specified minimum yield strength as a production casing in deepwater and high-pressure reservoirs has increased. Sulfide stress cracking (SSC) can develop when high strength carbon steel is exposed to a sour environment. The H2S partial pressure in these sour reservoirs is above the 0.03 bar limit for this material at room temperature. Materials SSC performance evaluation requires an accurate simulation of field conditions in the laboratory. To evaluate the production casing SSC behavior, some fit for service (FFS) tests were carried out considering the well geothermic temperature profile for the materials selection. This paper presents a fit for service qualification carried out on Casing 125 ksi SMYS (Specified Minimum Yield Strength) materials. Two products with 125ksi SMYS were considered: one that has existed for several years and one developed more recently with a better SSC resistance – above the pH2S limit considered for the standard 125ksi SMYS material. The results obtained in this test program allowed casing 125 ksi SMYS materials selection for temperature above 65°C and environment more severe in terms of pH2S than the domain previously established for this grade. This allowed a new well production design, which saves one casing phase and avoids the necessity to use intermediate liners to prevent collapse.

Abstract The common occurrence of sulfide stress cracking failures of many steels in the intergranular mode suggests a need for a better understanding of the grain boundaries, particularly the boundary chemistry. The boundary chemistry of selected high strength steels is correlated to the minimum stress at failure in hydrogen sulfide solutions at room temperature. The technique of Auger electron spectroscopy (AES) in a scanning Auger microprobe was employed to study grain boùndary composition and distribution of second phases at fresh fracture surfaces. The results indicate that S and Mn, precipitated in the form of a thin film of (Fe, Mn)S or P present at grain boundaries degrade the SSC properties of the material.
