“…It should be noted that the above techniques make it possible to comprehensively specify the procedure for calculating the mechanical parameters of a pipe with defects and, consequently, to improve the qualimetric approach to the quality issue related to UMP at oil and gas enterprises, which is partially presented in publications from Canada [23,24]. In addition, the quality criterion for UMP is partially represented in papers [9,10]. However, the cited studies [9,10,23,24] do not consider the effect exerted on the quality of UMP by mechanical stresses and parameters that characterize defects.…”

Сформовано новий критерій міцності та множину інформативних параметрів для моделювання напружено-деформованого стану (НДС) підземного металевого трубопроводу (ПМТ) з урахуванням системи дефектів типу каверна, у вершині якої знаходиться тріщина. Проведено обстеження поверхні труб із конструкційної вуглецевої сталі 20, на які діє внутрішній гідростатичний тиск. Запропоновано для критерію міцності металу труби, який контактує з грунтовим електролітом, враховувати стадії пружної та пластичної деформацій. Критерій міцності доповнено співвідношеннями для корозійного струму (типу Kaesche) і внутрішнього тиску, який діє на циліндричну трубу, з урахуванням непружної енергетичної характеристики поверхневого шару. Для трубопроводу в нейтральному грунтовому середовищі проведені вимірювання поляризаційних потенціалів і корозійних струмів апаратурою ВПП (вимірником поляризаційного потенціалу) і БВС (безконтактним вимірником струму). Результати вимірюють відповідні дефекти типу каверн (піттингів), які утворилися на зовнішній поверхні підземного трубопроводу. Для п'яти варіантів внутрішнього тиску p i =5,57,5 МПa приладами БВС та ВПП визначено струми та напруги для характерних поверхневих дефектів і на їх основі оцінено ефективний час досягнення тріщиною критичної глибини (ресурс труби), а також параметр надійності (характеристику безпеки) . Зі співставлення результатів експериментальних досліджень і відповідних розрахунків установлено, що відносні зміни швидкості корозії V cor у 2,8 рази і, відповідно, параметра ресурсу ПМТ t R в 3,1 рази більші, а параметра надійності  у 6,9 разів менші, ніж відносні зміни внутрішнього тиску p T. На основі аналізу параметра t R , який характеризує ресурс ПМТ, встановлено, що ця залежність t R від внутрішнього тиску p T нелінійна і прямує до насичення. Відзначена інформація є важливою для удосконалення методів контролю ПМТ нафтогазових підприємств, зокрема, методик коректного оцінювання густини анодного струму у дефектах металу на зовнішній поверхні підземного трубопроводу з урахуванням зміни внутрішнього гідростатичного тиску Ключові слова: підземні трубопроводи, нафтогазові підприємства, механічні напруження, гідростатичний тиск, корозійні струми, розкриття тріщини

A Materials Science Perspective of Midstream Challenges in the Utilization of Heavy Crude Oil

An increasing global population and a sharply upward trajectory of per capita energy consumption continue to drive the demand for fossil fuels, which remain integral to energy grids and the global transportation infrastructure. The oil and gas industry is increasingly reliant on unconventional deposits such as heavy crude oil and bitumen for reasons of accessibility, scale, and geopolitics. Unconventional deposits such as the Canadian Oil Sands in Northern Alberta contain more than one-third of the world’s viscous oil reserves and are vital linchpins to meet the energy needs of rapidly industrializing populations. Heavy oil is typically recovered from subsurface deposits using thermal recovery approaches such as steam-assisted gravity drainage (SAGD). In this perspective article, we discuss several aspects of materials science challenges in the utilization of heavy crude oil with an emphasis on the needs of the Canadian Oil Sands. In particular, we discuss surface modification and materials’ design approaches essential to operations under extreme environments of high temperatures and pressures and the presence of corrosive species. The demanding conditions for materials and surfaces are directly traceable to the high viscosity, low surface tension, and substantial sulfur content of heavy crude oil, which necessitates extensive energy-intensive thermal processes, warrants dilution/emulsification to ease the flow of rheologically challenging fluids, and engenders the need to protect corrodible components. Geopolitical reasons have further led to a considerable geographic separation between extraction sites and advanced refineries capable of processing heavy oils to a diverse slate of products, thus necessitating a massive midstream infrastructure for transportation of these rheologically challenging fluids. Innovations in fluid handling, bitumen processing, and midstream transportation are critical to the economic viability of heavy oil. Here, we discuss foundational principles, recent technological advancements, and unmet needs emphasizing candidate solutions for thermal insulation, membrane-assisted separations, corrosion protection, and midstream bitumen transportation. This perspective seeks to highlight illustrative materials’ technology developments spanning the range from nanocomposite coatings and cement sheaths for thermal insulation to the utilization of orthogonal wettability to engender separation of water–oil emulsions stabilized by endogenous surfactants extracted during SAGD, size-exclusion membranes for fractionation of bitumen, omniphobic coatings for drag reduction in pipelines and to ease oil handling in containers, solid prills obtained from partial bitumen solidification to enable solid-state transport with reduced risk of damage from spills, and nanocomposite coatings incorporating multiple modes of corrosion inhibition. Future outlooks for onsite partial upgradation are also described, which could potentially bypass the use of refineries for some fractions, enable access to a broader cross-se...
