You must submit at least one recommendation and documentation for entry exams (if applicable). U.S. law prohibits provision of certain services to individuals residing in embargoed countries; therefore, not all applicants may be eligible to participate in the Henry DeWitt Smith Fellowship program. Born in Plantsville, Conn. in 1883, Mr. Smith received his E.M. from Yale's Sheffield Scientific School in 1910. As one of the last junior engineers trained by Josiah Edward Spurr, he saw most of the western part of the U.S. and much of Mexico. Following that period, he became foreman at Kennecott's Alaskan copper mine and successively rose to mine superintendent and assistant manager.
The decision may alleviate some of the pressures oil and gas producers faced in the wake of their imposition last year. Canada and Mexico made up a combined 20% of US imports of oil country tubular goods in 2017. Operators are increasing capital budgets in the wake of tariffs and quotas initiated by the US government on steel imports, and the product exclusion process has revealed a host of other issues. If the tariffs are here to stay, what does industry hope to see moving forward? How will a US steel tariff affect the oil and gas supply chain?
Richard Boakye Yiadom, EIT from Ghana, West Africa, is currently a MS in petroleum engineering candidate at the University of Utah. He received his BS in mining engineering from the University of Utah and was a recipient of the prestigious McIntosh Engineering Scholarship by the SME Foundation. Before joining the program, he worked as a mine engineer for Peabody Energy at their Twentymile Mine in Colorado and Rawhide Mine in Wyoming. At Peabody Energy, Yiadom put together and supervised several high capital projects and carried out mine planning projects. Among his achievements, he generated a water model for the mine and recommended a booster pump location.
It is well understood that strength to weight ratio is an important driver facilitating extended reach deviated wells, as such engineering corrosion resistant ultra-high-strength light-alloys (LAs) are an absolute necessity. High strength steels and nickel alloys, having yield strengths between 80 and 120 ksi, commonly used in oil & gas completions and production, have 3 to 5X higher specific gravity compared to LAs. In comparison, commercial coarse-grained polycrystalline light-alloys (CGP-LAs) have a much lower strength, typically less than 45 ksi yield strength and are not corrosion resistant. However, if strength of LAs can be increased to match that of steels and nickel alloys while simultaneously augmenting their corrosion and environmental assisted cracking (EAC) resistance through severe plastic deformation (SPD) routes, manifesting an ultra-fine-grained (UFG) microstructure, they will far surpass strength to weight ratios of steels and nickel alloys.
As such the quest for a perfect alloy with the right combination of strength, ductility, corrosion, and abrasion resistance is ever ongoing. The advent of nanotechnology and advancements in engineering nanostructures with high strengths and reasonable ductility has motivated researchers globally [
To determine if grain refinement in a LA, and resultant Hall Petch strengthening, where strength of the UFG-LA surpasses that of commercial coarse-grained oil-grade steels, is instrumental in enhancing its EAC resistance, focused experiments were conducted. An aluminum-magnesium CGP-LA commonly used in offshore and marine applications was selected and subjected to SPD resulting in an UFG microstructure. Both CGP-LA and UFG-LA specimens were exposed to environmental conditions to compare their corrosion and EAC and resistance.
It was observed from polarization measurements and immersion tests that UGF-LA had better corrosion resistance than CGP-LA. Uniaxial tensile tests in a neutral halide environment for various holding times confirmed that strength and ductility was maintained for UFG-LA specimens while catastrophic failures of CGP-LA specimens were observed. It was also evident from orientation images that grain boundaries in UFG-LA were predominantly high-angle in contrast to CGP-LA. The improved corrosion and EAC resistance of UFG-LA was due to a large number of purer grain boundaries with nanocrystalline impurities distributed infrequently along them.
These results are very topical as they highlight the possibility of harnessing the enhanced strength to weight ratios of these unique alloys for designing buoyant thin walled flowable shells for deployment in high pressure high temperature (HPHT) oilfield environments, from vehicles being designed for interstellar gas giants to aggressive sour oilfield reservoirs.
Subsea mining increasingly plays an important role in the extraction of raw materials. The decentral automation is the next generation of this technology. The conventional hydraulic drive systems were not able to fulfil the requirements of slow speed parallel drive operation of the chain drives of the vehicle with a sufficient result.
Tubular steelmaker Vallourec Group announced a reduction in force of about 900 North American employees—one-third of its workforce—citing as reasons a “substantial decline in the demand for the company’s products and services and a significant reduction in its incoming receivables and cash flow” amid US energy woes. To balance a 50% drop in drilling activity, the company also adjusted its production, eliminated nonessential expenses, and launched a hiring freeze. In a separate announcement, Vallourec made changes to executive-level responsibilities in its North American and US divisions and at its French headquarters. The job cuts are the latest for steel companies that serve the North American oil and gas industry. US Steel and Luxembourg-based pipemaker Tenaris recently announced cuts and closures at their US tubular facilities.
