Case Summary:

For this EB-2 NIW case, we worked closely with a Postdoctoral Research Associate who has made substantial contributions to the field of Petroleum Engineering. In his research endeavors, our client has addressed some of the most pressing issues in his field, specifically regarding the optimization of drilling techniques to reduce drilling costs, the development of new methodologies to assess cuttings transport in wellbores, the characterization of two-phase drilling fluid flow through inclined eccentric annular geometry, the determination of the cuttings transport properties of gasified drilling fluids, the simulation of the interactions between cuttings and drilling fluid in horizontal eccentric annulus, and the development of a novel equivalent circulating density calculation procedure to model gasified drilling fluids. Because the United States is one of the largest consumers of energy in the world, our client’s work provides critical solutions to the serious issues of reducing oil well drilling costs by optimizing drilling parameters, as well as developing and using modeling tools to improve performance of drilling procedures and tools.  His cutting-edge research has culminated in the authorship of a book, 5 technical reports, and 3 peer-reviewed scientific manuscripts that were published in the top journals of his field. These publications have been cited 29 times by independent researchers worldwide, and he presented his work 16 times at several highly distinguished international conferences, demonstrating the global demand and recognition for his research endeavors.The significance of his work to the broader scientific community was endorsed by an independent recommender, who stated, “As his research is being relied upon by labs and companies across the nation and world, he is having a great impact on the US. He has proven himself to be of extraordinary talent and his record of accomplishments is impressive. It would be a detriment to the field, and thus to the American people, if [Client] were not able to work in the United States. I believe that the United States needs [Client] to devote his talents, because his work will advance the drilling engineering research with a focus on industry needs.” With the extensive and thorough documentation that we provided, we were able to prove that our client’s social and scientific advancements and continued research have substantial merits for our country and the scientific community as a whole, thus he has served the nation to a significantly greater degree than that of others with similar education and experience. We were met with success when his NIW petition was approved in 5 months.
