Laboratory selection of oilfield corrosion inhibitors used to mitigate carbon dioxide (CO2) and hydrogen sulfide (H2S) corrosion is an essential aspect of every asset integrity program implemented in oil and gas fields. However, many factors increase the complexity of designing a corrosion inhibitor laboratory test program that will deliver reliable results. Several of these factors relate to the challenges of accurately replicating field conditions in the laboratory, including using inhibitor-free crude oil, reproducing pipeline flow regimes and wall shear stress, duplicating the specific form of corrosion that occurs in the field, and simulating inhibitor deliverability and transport in multiphase pipelines. Other elements that increase the difficulty relate to requirements for environmentally acceptable chemistries in certain geographies and the variety of corrosion performance tests and methodologies mandated by different oil companies. After the laboratory testing is complete and a corrosion inhibitor has been selected for field application, optimization of the product in the field should be performed but this is frequently overlooked. If corrosion inhibitor treat rate is not optimized in the field, it can result in overdosing (causing stabilization of emulsions and foaming) or underdosing (which can result in high corrosion rates). This paper discusses the challenges and inconsistencies associated with selecting corrosion inhibitors for use in oil and gas fields. Importantly, this paper discusses how these challenges can be resolved to ensure that the selection of oil and gas corrosion inhibitors follows a reliable process.

Significance of Evaluation Methods for Surface Applied Corrosion Inhibitors

Product Number: 51218-113-SG

Author: Fred Goodwin

Publication Date: 2018

$20.00

Surface Applied Corrosion Inhibitors (SACI) remain controversial as to effectiveness and the ability to compare materials from different manufacturers and technologies. These materials are liquids applied to the surface of concrete to control the corrosion of embedded reinforcing steel. This presentation will discuss the performance and relative importance of a recent testing program for corrosion inhibition and other performance parameters using documented test methods.

Silica Solubility in High Enthalpy Water up to 440°C in the Presence of NaCl

In geothermal energy production, precipitation/scaling and potential plugging of wells is one of the major threats to flow assurance. Mitigation strategies should be considered at the design stage, but to do so knowledge about solubility across a relevant space of temperature, pressure and fluid composition is needed. In hot fluids, silica scaling is often found to be the major concern. Predictive models available in literature give good agreement with experimental values in the region where data are available, but there is limited data available at high temperatures and low pressures, in particular in the presence of salt. This work describes an experimental setup designed to carry out solubility experiments up to 500 °C and 400 bar. A main feature of the setup is the ability to dilute the sample fluid in the hot zone in order to avoid precipitation during sampling. Illustrations are given for how existing phase relations can be used to guide the execution of such high-pressure high-temperature experiments. Results of silica solubility experiments in the presence of NaCl up to 440 °C at 150-350 bar are presented. This work includes data at the steam side pseudocritical line (critical density isochor) where limited data is available in the literature. The experimental concept, with hot zone dilution to avoid precipitation during sampling, can be used to obtain fluid samples as a function of time. Although utilized in the current work for solubility experiments it should be equally applicable to corrosion studies.

Silicate Resins for Sustainable Heavy Duty Coatings

Product Number: 51324-21213-SG

Author: Kristen Blankenship; James Lawson

Publication Date: 2024

Extending service life of an asset brings value to the owner and has the added benefit of reducing environmental impact. Arguably the biggest threat to service- life is degradation. When constructing with steel, corrosion is the threat to mitigate. Zinc dust incorporated into silicate resins have offered corrosion protection for heavy duty coating applications since the latter half of the last century. In recent years silicate finishes formulated without zinc have entered the market to create a two- coat system offering superior corrosion protection in a finish with various color options. The silicate finish or topcoat is low carbon and resilient to UV degradation allowing it to protect the zinc- rich primer from damage. For applications where a lower gloss finish is desired or appropriate, this technology offers decades long durability sustainably. This paper will explain what a two- coat silicate resin- based coating system is, how it works, what it looks like and most importantly how it reduces environmental impact through increasing service life of assets.Protective coatings, Corrosion control, Degradation, Durability, Coating lifecycle

Carbon dioxide (CO₂) saturated brines containing high levels of calcium are commonly encountered across the energy sector: from hydrocarbon recovery to the harvesting of geothermal energy and re-deposition of CO₂ for permanent storage. These brines originate in deep underground reservoirs at elevated pressures and temperatures. Despite susceptibility to corrosive attack under these conditions, carbon steels are the preferred choice of pipeline materials for such processes, attributable to their low cost, availability and ease of manufacture.

TSA is mainly used to protect offshore steel structures, including atmospheric, splash and immersed zones. During installation or in service, the coating is likely to be damaged due to erosion, wear, scratch etc. TSA coatings protect by acting as a barrier and offering cathodic protection even if the substrate is exposed to seawater.

Corrosion on steel bridges has long been recognized as a major concern. Over the years, technology has advanced from lead-based paints used for a century to three-coat systems. Recently, two-coat systems have been developed and are gaining acceptance. Research which is now underway to develop a one-coat system is described in this paper.
