Fast-Acting And Persistent Post-Hydrotest Corrosion Inhibitors For Newly Constructed Oil Pipelines

Pressure testing is a standard practice used to validate the condition of new pipelines (prior to wet commissioning) and may also be used to revalidate the integrity of older pipelines. Since water is the primary medium for pressure testing, the process has been termed hydrostatic testing or hydrotesting. While the low cost, accessibility and environmental impact are primary drivers for use of water, the inherent corrosiveness of water poses an asset integrity challenge.

Mineral scale deposition and pipeline corrosion are two of the most common challenges that require chemical treatment in oil wells. Combination products including scale inhibitor (SI), corrosion inhibitor (CI) packages, surfactants, and other chemical additives are well accepted as an integrated solution to flow assurance and asset integrity problems. In this work, a case study in the Permian Basin field demonstrates a certain type of combination product exhibiting lower performance than expected. The raw material interference on the scale inhibitors was investigated and presented with detailed laboratory data. A series of laboratory tests were conducted to investigate the impacts on performance from the chemicals in the combination product. In the dynamic tube blocking test, the phosphonate-based SI shows much weaker performance in the presence of certain active CI components, while other raw materials (surfactants and quaternary amine) had a minor effect. Further bottle tests revealed a calcite inhibition drop from complete inhibition to 30% and 40% inhibition in the two phosphonate-based SI chemistries in the presence of the active component, respectively. In the additional barite inhibition tests, no significant impact on the SI performance was observed. Contrary to the previous literature reports about common CI chemicals, this active component expressed significantly adverse impacts on the SI performance for calcite prevention. This study demonstrates a root cause analysis for the adverse effect of certain active CI components on the scale prevention and suggests the impact of the CI package on SI should be carefully investigated in the product selection. A thorough evaluation of combination product performance is recommended before the field application.

Hydrocarbon production currently occurs in a variety of onshore and offshore locations. Most offshore production in shallow water (< 500 m) has reached maturity, with most of the more accessible reserves having already been exploited. As a result, exploration and production in offshore environments has been extended to deeper water (> 500 m), which usually incurs more expense and overall project risk for operators and service providers. Production from deepwater oil fields is expected to grow by 40%, to 10 million bpd (10% of total global output), by 2025.

Influence of Hydrocarbon on Stearic Acid as Corrosion Inhibitor in Synthetic Brine

Product Number: 51323-19330-SG

Author: Susumu Hirano, Tatsuya Sei

Publication Date: 2023

Corrosion inhibitors are used for carbon steel pipelines in the oil and gas industry. Based on current
understanding, the inhibitor molecules mitigate corrosion through adsorption to the internal surface of
the pipeline, forming a barrier film that impedes electrochemical corrosion reactions at the metal
surface. Micellization is a key factor of the surfactant distributions.

Over the past decade, there has been increasing interest in the corrosion behavior of carbon steels in supercritical CO₂ conditions. Unlike the case of carbon capture and storage (CCS) where small amounts of water are present, the exploitation of fields with high pressures of CO₂ needs to consider the presence of formation water, which presents strong corrosivity. It has been reported that the aqueous corrosion rate of carbon steel at high CO₂ pressures (liquid and supercritical CO₂) without protective FeCO₃ corrosion product layers is very high (>20 mm/y) due to the high concentrations of corrosive species such as H⁺ and H₂CO_³.^1-5 Steels with low Cr contents (i.e., 1% Cr and 3% Cr) have shown no beneficial effect in terms of reducing the corrosion rate to admissible values.6 Therefore, controlling corrosion in these cases usually involves the use of corrosion resistant alloys (CRAs) or corrosion inhibitors (CI). Adequate protection of carbon steel was achieved by applying CI in high pressure CO₂ environments.⁶

Investigation on the Mechanism of Corrosion Inhibitors by Contact Angle and Surface Tension

Product Number: 51324-21173-SG

Publication Date: 2024

Corrosion is common, costly and a prevalent industrial problem in the oil and gas industry. Corrosion inhibitors, which are surfactant-like molecules, adsorb on the metallic surface of a pipe to form a barrier film that inhibits interactions of the pipe surface with corrosive species. Despite the prominence of surfactants as corrosion inhibitors, their adsorption behavior inside a pipeline is not well understood. In this study, continuous corrosion inhibitors were evaluated to correlate corrosion performance testing with contact angle and surface tension studies. Contact angle method was employed in corrosion inhibition studies for surface characterization. Surface tension method was used to determine critical micelle concentration. Contact angle results showed that for the water-soluble continuous corrosion inhibitors such as quaternary ammonium and imidazoline, a monolayer and bilayer were formed on the metal surface as reflected by an increase and then decrease in contact angle. The bilayer further increased the corrosion inhibition efficiency until the critical micelle concentration (CMC) was reached for quaternary ammonium and imidazoline only. However, the mixed quaternary ammonium and imidazoline in the formulation resulted in the maximum contact angle value being at its CMC indicating a compact monolayer formation. The results can provide a helpful guideline for further studying the synergistic effect of corrosion inhibitor mixtures.

At present, with the increasing in demand for natural gas, all gas production companies are increasing their efforts in natural gas exploration and development. Corrosion is one of the problems during the wet gas transporting, and this can be solved by adding corrosion inhibitor(CI) in most case. However, there are no standards for the Cis performance used in gas gathering and transportation pipelines, which may lead to some gapsbetweentheR&Dscientistsandtheneedsofcorrosioninhibitorusers. Based on the demand of some gas production companies for the CIs, this paper puts forward the performance requirements and corresponding indexes of Cis for natural gas gathering and transportation system, and given some advice on the evaluation method.

Throughout the oil and gas industry, carbon steel continues to be the material of choice for most downhole production tubulars and pipelines. Given the environment of typical oilfield operations, comprehensive integrity management programs are followed to guard against the threats of internal corrosion and material degradation of such assets. Although there are various corrosion mitigation options available, the application of corrosion inhibitor chemical products is commonplace given their relative ease of use and cost effectiveness.

Offshore wind turbines are subjected to a harsh marine environment, which can cause detrimental problems to them due to corrosion, if not protected properly. Offshore wind energy is considered to play an important role in the net zero emissions by 2050, as set in Paris Agreement [1], contributing to environmental protection and sustainability. Thus, the long-term corrosion protection and life expansion of these offshore structures is of high importance. In this work, the formation of microcapsules, loaded with corrosion inhibitor liquid is presented. More specifically the microcapsules consist of polystyrene shell-an inert material- and 3-octanoylthio-1-propyltriethoxysilane core with a mean diameter of around 80µm. Silanes are used as corrosion inhibitors due to their chemistry, which offers protection to the underlying substrate [2, 3]. The incorporation of the microcapsules in a commercially available paint and their anticorrosion performance was tested in salt spray chamber and in real marine environment. Hence, this work highlights the performance of the microcapsules, which can offer corrosion solution to offshore wind turbines when used as part of a coating system. EDX analysis of the exposed samples lead to conclusions regarding these systems, contributing to the existing literature.
