During the last decades, low alloyed steels with improved resistance to Sulfide Stress Cracking (SSC) have been developed for covering specific applications as heavy wall casings1 or expandable tubings2 or for reaching higher mechanical properties, such as 125 ksi Specified Minimum Yield Strength (SMYS) materials.3-6 For the latter, relevant sour environments for developed grades are mild, meaning that all sour applications cannot be covered while a strong interest exists for O&G operators to use high strength materials when designing wells. Consequently, there is an incentive to push the limits of use of high strength sour service steels by enhancing their resistance to SSC. Several recommendations were already published when designing high strength sour service grades: hardness level shall be limited as much as possible and be preferentially below 22 HRC7, microstructure shall present a minimum required amount of martensite8 which is well known to be ideal for combining high mechanical properties and high resistance to hydrogen. Besides, many authors highlighted some other influencing parameters related to the material or the process.

The needs of oil and gas operators are challenging the industry to push the limits in sour service materials always further by finding the best compromise between high strength steels and good resistance to Sulphide Stress Cracking (SSC). It is in this context that materials have been recently developed, so as to respond to increasingly severe service with high level of Specified Minimum Yield Strength (SMYS). This communication presents the combination of computational modeling methods, advanced metallurgical characterization techniques, scale-up methods (from laboratory to mass production) for designing sour service steel grades with improved SSC resistance. Basics, pros and cons of several tools are discussed; namely X-Ray Diffraction from synchrotron beam, Transmission Electronic Microscopy, Electron Back Scatter Diffraction, Thermo-CalcTM. Their efficiency to optimize design has been validated on a selection of lab casted prototypes and applied to the development of a new 125 ksi SMYS material with enhanced SSC resistance, able to sustain 0.1 bar H2S at ambient temperature. Some results demonstrating the SSC resistance as evaluated with NACE TM0177-2016 Method A of the newly developed steel sampled from pipes already produced at industrial scale will be shown.

A life cycle cost assessment led to the selection of DSS for field gas gathering network composing of more than 200 miles of pipelines. Buried portions are provided with external coating. Furthermore, due to high chloride content in the soils, the external corrosion threat was mitigated through the use of an external coating supplemented with CP. 

As there was no industrial reference covering onshore DSS pipeline CP criteria, lab testing was conducted to establish the criteria and confirm if the risk of hydrogen embrittlement is managed appropriately. This is further evaluated with field data to confirm pipelines integrity.

Corrosion control of buried assets usually involves a double shield: a coating system as a physical insulation barrier, and a cathodic protection system as an additional ad hoc defense. Detection of a corrosion spot at the coating defect stage is the only way to identify the threat before significant metal loss occurs. Furthermore, detection of defects in the coatings of such assets is especially important, since large defects, if left unrepaired, will not only leave the asset locally prone to corrosion, but also drain and weaken the cathodic protection effectiveness for the entire structure. Therefore, identification and characterization of coating anomalies is critical for the integrity of buried assets.

Erosion is one of the major threats of the pipeline integrity1 when it’s transporting liquid hydrocarbon products with solid particles. The erosion process decreases the effective wall thickness and therefore reduces the capacity of the pipeline to contain the pressured product. This can induce serious consequences including property, health and safety, environment, and business costs.
