Metallic material requirements for resistance to sulfide stress cracking (SSC) for petroleum production, drilling, gathering and flowline equipment, and field processing facilities to be used in H2S-bearing hydrocarbon service. Historical Document 1993
The problem of corrosion in wastewater structures. Renewal technologies for rehabilitation, repair, and replacement of existing systems, structures, and components.
Materials selection, fabrication, postweld heat treatment, inspection, and testing practices for pressure vessels to reduce the likelihood of low-temperature hydrogen damage in wet H2S environments.
Published reports of laboratory tests and plant experience pertaining to the cracking of steels in wet H2S service. Environmental, fabrication, and metallurgical parameters involved in the cracking process.
During the 72-year history of using high performance coating systems for pipe internal corrosion control, there has been a slow introduction of different resin chemistries that serve as the backbone of these coating systems. While phenolic resins systems were the primary starting point, it transitioned to include epoxies, novolacs, nylons, urethanes and others. As needs outside corrosion control like deposit mitigation and wear resistance arose, coatings based on other specialty resin chemistries, like from the fluoropolymer family, were developed.
Biocides are used in hydraulic fracturing operations to control the growth of contaminant microorganisms that lead to corrosion, souring, and conductivity loss.1,2 A variety of biocides are utilized and can be classified by mechanism of action, speed of kill, and the length of residual activity.In general, rapid-acting biocides such as chlorine dioxide (ClO2) and DBNPA (2,2-dibromo-3- nitrilopropionamide) inactivate bacteria quickly but have little to no residual activity. Glutaraldehyde (Glut) reacts more slowly and provides some residual activity, particularly at lower wellbore or reservoir temperatures.
13Cr-5Ni-2Mo type Super Martensitic stainless steels referred to as SMSS-13Cr type grades can provide good general corrosion resistance such as in high CO2 environments combined with higher strengths and excellent toughness2 making them a prospective material choice for long term downhole completion equipment depending on actual well conditions. One of the main limiting factors for the use of SMSS-13Cr type grades is the Sulfide Stress Cracking (SSC) resistance in presence of H2S in downhole well conditions. Therefore, a good understanding of this behavior is essential to facilitate the material selection process.
