Selective laser melting (SLM) is a widely used additive manufacturing (AM) process, also for producing components using precipitation-hardenable nickel alloy 718 (UNS N07718). SLM has been largely accepted into many industries including oil and gas (O&G) with current research efforts focused on demonstrating materials performance in demanding applications including directional drilling and reservoir characterization tools. A broader applicability of additively manufactured UNS N07718 in such applications is currently conditioned by characterization efforts limited to corrosion testing on machined surfaces, which are not representative of the surface resulting from SLM process. The lack of understanding regarding the influence of as-printed surface conditions for UNS N07718 produced via SLM on fatigue and corrosion fatigue limits its applicability to the machined surface condition, thus negating benefits gained during the manufacturing process. In this research work, the fatigue and corrosion fatigue behavior of additively manufactured UNS N07718 in as-printed conditions was investigated. Besides fatigue in air at ambient temperature, corrosion fatigue of SLM718 was tested in alkaline 5 M chloride-containing brines at 125 °C to simulate a typical drilling environment. Experimental results have shown that as-printed surfaces of SLM718 are significantly more prone to fatigue and corrosion fatigue compared to machined surfaces. Besides increased surface roughness the presence of near-surface defects typical of AM can be seen as the reason for the observed fatigue behavior.

The application of corrosion inhibitors are fundamental to the safe and reliable operation of carbon steel infrastructure, presenting one of the most cost effective methods of internal pipeline corrosion control when deployed correctly. Despite decades of application in the oil and gas industry, a number of gaps remain in relation to our fundamental understanding of the performance of inhibitors. This is particularly true in the context of partitioning, and more so when the system under consideration comprises multiple surfactants. Part 1 of this two-part paper provides a detailed insight into the fundamentals of surfactant partitioning. Initially, the role of micellization in influencing single surfactant partitioning/distribution behavior between oil and brine is discussed, providing theoretical explanations for single surfactant system responses. The complexity of the systems examined increases with consideration extending to multi-surfactant environments, accompanied by discussion of idealized theoretical behavior. Subsequently, an idealized model to predict multi-component distribution responses between oil and brine is presented. To explore the model’s capabilities, experimental partitioning and micellization data collected from previous studies for two benzyl ammonium chloride corrosion inhibitors (BAC-C12 and BAC-C16) is integrated into the model. Such integration permits investigation into the effect of surfactant concentrations, relative surfactant molar ratios and water cut on partitioning/distribution behavior.

Mitigating global warming and reducing CO2 emissions from the environment necessitates the implementation of carbon capture, sequestration, and storage (CCS) as an immediate and feasible solution. Amines are widely employed to capture CO2 gas from industrial exhaust streams. To enhance the cost-effectiveness of amine services, the incorporation of glass-reinforced plastic material holds immense potential for substantial cost benefits. The primary aim of this study is to assess the feasibility of utilizing glass-reinforced plastic (GRP) as a construction material for vessels, piping, and ducting in the cold section of the carbon capture and storage (CCS) system. The research examined the potential of completely replacing metallic equipment and piping (such as carbon steel (CS), stainless steel (SS) or SS cladded CS) with GRP materials. The investigation revealed that complete substitution of GRP for certain CO2 service components, including the scrubber, pre-scrubber, tanks, piping, and ducting, may be feasible under specific process conditions. These process conditions encompassed temperatures below 100°C, pressures below 10 bar for piping, and pressures below 0.2 bar for the remaining components. Two fabrication methods, filament winding and contact molding, were employed throughout the design calculations and utilizing corresponding material properties. A chemical compatibility study by Shell, presented at the 2023 AMPP conference and expo (Paper # AMPP-2023-18832), confirmed that the selected resins used to prepare the GRP material are chemically compatible with the commercial amine formulation used for CO2 capturing at the same application limit identified for the present work. The study unequivocally confirmed that glass-reinforced plastic can be incorporated with confidence, adhering to the safety limits prescribed by international standards. This resounding validation strengthens the viability and applicability of GRP in the given context, bolstering its position as a reliable and suitable construction material.
