Between the phases of oil exploration and production, there is this oil transfer through natural or artificial elevation method. When this method is natural, the pressure in the reservoir is sufficiently high and the fluids in it can emerge to the surface, but when this pressure is insufficient, the fluids do not reach the surface without the use of artificial lifting methods. Among the struggles to be solved by engineering, there is the optimization of the geometry of the lift gas valves (VGL) and the sealing material. In this context, this article presents the prospecting of papers and patents related to the technological advances of VGL published in the last five years (2016 to 2020) and as a research contribution, there is the identification of solutions regarding the aforementioned optimization. The ScienceDirect, Scopus, CAPES Periodical Portal, and Web of Science databases were used, and the patent search in the database of the European Patent Office (EPO), Espacenet. The results showed that the number of papers published in this area is low, showing that there have been more publications on the subject in the last three years. In addition, China and the United States of America are the countries with the highest number of patents granted in the years surveyed, and the two North American inventors have the greatest number of inventions.
Indicação Geográfica (IG) é o termo que identifica produto ou serviço característico de certa localidade, agregando valor ao bem e trazendo vantagens ao produtor, ao consumidor e à economia. Neste contexto, o objetivo deste artigo é apresentar conceitos acerca do reconhecimento das IG, traçando breve panorama das indicações da região Nordeste do Brasil, além de dispor das oportunidades e desafios para o fortalecimento de negócios locais. Para tanto, são utilizados dados dos portais Periódicos CAPES e biblioteca digital Scielo, além de consultas nos sites do INPI, IBGE e Sebrae. Como resultados destaca-se a necessidade da criação de políticas, além do aprofundamento de estudos em IG, pela sua importância econômica e social. Nota-se que os principais desafios estão nas dificuldades de gestão e alinhamento estratégico das IG, já as oportunidades são geradas com apoio de tecnologias digitais de informação e comunicação que inovam e fortalecem as IG e os negócios relacionados.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
