Design and Construction of a Lateral Micro-Drilling Autonomous Robotic SystemSantiago Guevara Ocana (11197434) 04 December 2023 (has links)
<p dir="ltr">This research project aims to develop a robotic platform capable of drilling horizontal laterals from existing wellbores, offering data-guided steering and control features using information captured by sensors. The project provides an opportunity to expand the application of downhole drilling robots toward semi-autonomous operations in existing fields, especially those with declining production. Mature fields represent a global resource, and even modest hydrocarbon reserves additions are substantial to keep up the energy demand, having positive economic and environmental impacts. Available lateral drilling techniques do not fit the constraints offered by the challenge; moreover, they are not cost-effective.</p><p dir="ltr">The project will be organized into three phases to accomplish this developmental study. First, design criteria and key performance aspects will be identified and established to design a self-propelled robotic prototype capable of drilling lateral sections from an existing wellbore with an internal diameter of 4” to 6”. The creation of lateral sections can potentially add hydrocarbon reserves taking advantage of an already-drilled vertical section of a mature field. Second, the design of the prototype will take place, along with the design of a sub-surface communication and control system. The third phase is manufacturing and subsystems integration, finishing with a pilot test in a controlled environment. Based on the pilot testing results, design optimization will occur. Finally, a field version will be designed, and IP (Intellectual Property) disclosures and plans for commercialization will be identified and addressed.</p>

[pt] CONTEÚDO LOCAL E OS LEILÕES DE PETRÓLEO E GÁS NO BRASIL / [en] LOCAL CONTENT IN BRAZILIAN OIL AND GAS AUCTIONSDAVI DONEDA MITTELSTADT 02 December 2019 (has links)
[pt] Nesse artigo, estudamos os leilões de petróleo e gás no Brasil para medir o impacto de requerimentos de conteúdo local nos lances realizados, o que nos permite estimar o seu impacto na receita obtida pelo governo. O caso brasileiro é particularmente atrativo, uma vez que houve variação significativa das exigências de conteúdo local ao longo do anos. Nas rodadas em que os requerimentos foram mais altos, observamos uma mudança significativa no comportamento dos participantes dos leilões: o bônus de
assinatura médio em blocos offshore caiu de uma média de 57 milhões de reais nas primeiras rodadas para apenas 10,6 milhões de reais, e o número médio de lances por bloco caiu de 0,92 para 0,12. Nosso objetivo é responder em que medida a elevação das exigências de conteúdo local afetaram participação e
receita nos leilões. Nós desenvolvemos e estimamos um modelo estrutural de leilões dentro do arcabouço de valores comuns que inclui a decisão de entrada e lances em múltiplas dimensões, incluindo um bônus e um percentual de conteúdo local. Nossos resultados mostram que as exigências de conteúdo local elevam os custos em blocos em águas profundas em 14 por cento. A receita governamental em leilões nessas áreas poderia ser muito maior em um contrafactual sem exigências de conteúdo local, contabilizando 17 bilhões de reais em receita de bônus de assinatura apenas em águas profundas. Em blocos em terra, não encontramos diferenças significativas de custo local e estrangeiro. / [en] In this paper, we study the case of Brazilian oil and gas auctions to assess the impact of local content requirements in bidding behavior, allowing us to estimate its impact on government revenue. The Brazilian
case is particularly appealing, as there were significant changes in these requirements throughout the years. In the sales with increased local content requirements there was a dramatic change in the bidders behavior: the average signing bonus for offshore tracts dropped from an average of 57 million reais in the first sales to only 10.6 million reais and the average number of bids per tract plunged from 0.92 to 0.12. We aim to answer how much the increased local content requirements affected participation and revenue
in the auctions. We develop and estimate a structural auction model within the mineral rights framework that includes an entry decision and bids in multiple dimensions, including a bonus and a local content percentage. Our results show that local content requirements increase costs in deep water areas in 14 por cento. Government revenue in auctions in these areas could be much larger in a counterfactual with no local content requirements, amounting to an extra 17 billion reais in signing bonus only for deep-water tracts. For onshore areas, we did not find any significant difference between local and foreign costs.

[en] DETERMINING FACTORS FOR THE OPERATIONAL PERFORMANCE OF SMALL BUSINESSES IN THE OIL AND GAS SERVICES SECTOR / [pt] FATORES DETERMINANTES PARA O DESEMPENHO OPERACIONAL DOS PEQUENOS NEGÓCIOS DO SETOR DE SERVIÇOS DE ÓLEO E GÁSLUDMYLLA DA SILVA MOREIRA 09 March 2020 (has links)
[pt] Este trabalho fundamentou-se na teoria da visão baseada em recursos (RBV) e nas cinco forças competitivas de mercado para identificar e analisar os fatores determinantes para o desempenho operacional de pequenos negócios prestadores de serviços, evidenciando os facilitadores e barreiras para o desempenho dos mesmos. Utilizou-se como métodos de pesquisa a revisão sistemática da literatura (RSL) para identificar os principais determinantes e o estudo de caso para explorar como os pequenos negócios abordam esses determinantes em seu desempenho operacional. Neste contexto, este estudo foi realizado junto a quatro pequenos negócios prestadores de serviços do setor de petróleo e gás, parceiras do Serviço Brasileiro de Apoio às Micro e Pequenas Empresas no Estado do Rio de Janeiro (SEBRAE/RJ). Como resultados da RSL, identificou-se a inovação e a orientação ao mercado como os principais determinantes frequentemente relacionados ao desempenho de pequenos negócios em serviços. Os principais facilitadores identificados foram qualidade, capital humano e inovação de produto/serviço, enquanto que recursos limitados e funcionários desqualificados foram identificados como as principais barreiras. Assim, na análise dos resultados dos estudos de caso observou-se que a competitividade e o crescimento no mercado são as forças que direcionam as atividades de inovação, logo, a orientação ao mercado se torna necessária paras as empresas direcionarem suas ações de maneira estrategicamente assertiva e, com a inovação, as organizações visam melhorar seus desempenhos, gerando vantagens competitivas ao oferecer novos serviços. / [en] This work was grounded on the theory of the resource-based view (RBV) and the five competitive market forces to identify and analyze the determining factors for the operational performance of small service providers, showing the facilitators and barriers to an improved performance. The systematic literature review (SLR) was used as a research method to identify the main determinants and a case study to explore how small businesses address these determinants in their operational performance. In this context, this study was carried out with four small oil and gas service providers, which work in partnership with the Brazilian Micro and Small Business Support Service in the State of Rio de Janeiro (SEBRAE/RJ). As SLR results, innovation and market orientation were identified as the main determinants often related to the performance of small businesses in services. The key facilitators identified were quality, human capital, and product/service innovation while limited resources and disqualified employees were identified as the main barriers. Thus, in the analysis of the results of the case studies, it was observed that competitiveness and market growth are the driving forces for innovation activities, so market orientation becomes necessary for companies to target their actions in a strategically assertive way and, with innovation, organizations aim to improve their performance generating competitive advantages by offering new services.

[pt] OS INCUMBENTES E A TRANSIÇÃO ENERGÉTICA: FATORES ANTECENDENTES AO ENGAJAMENTO E IMPLICAÇÕES NA GERAÇÃO DE VALOR PARA O MERCADO / [en] THE INCUMBENTS AND THE ENERGY TRANSITION: ANTECEDENT FACTORS TO ENGAGEMENT AND IMPLICATIONS ON MARKET VALUE GENERATIONLUCIANO FELIPE DE CARVALHO RODRIGUES 19 July 2024 (has links)
[pt] Na emergência global das mudanças climáticas, um eixo fundamental para a
mitigação é associado ao setor energético, que representa 77% das emissões globais
de gases de efeito estufa. O fenômeno global caracterizado pela substituição de
fontes de energia fósseis por fontes de energia renováveis, visando a redução das
emissões é denominado de ‘Transição Energética’. Neste contexto, as empresas
incumbentes do setor de óleo & gás se encontram no centro deste dilema
estratégico, uma vez que este setor responde por 50% da demanda global de energia
e são focadas em fontes de energia fósseis, emissoras de gases de efeito-estufa. Este
estudo visa esclarecer os fatores que precedem o engajamento na transição
energética por empresas incumbentes do setor de óleo & gás, fazendo-as vencer a
inércia organizacional e adotar estratégias que as levem a se adaptar à mudança de
cenário global pela qual passa este setor. Com estudo plurianual (2017-2022) e
ampla base de dados (168 empresas do setor) foram aplicados testes empíricos para
verificar os fatores antecedentes ao engajamento das empresas incumbentes do
setor de óleo & gás. Observou-se que a vigência do acordo de Paris, a natureza do
controle acionário e a importância do segmento de upstream são fatores que
influenciam no engajamento das empresas incumbentes do setor de óleo & gás. / [en] In the global climate change emergency, a fundamental axis for mitigation is
associated with the energy sector, which accounts for 77% of global greenhouse gas
emissions. The international phenomenon characterized by replacing fossil energy
sources with renewable energy sources, aiming at emissions reduction, is termed
Energy Transition. In this context, incumbent oil and gas sector companies find
themselves at the center of this strategic dilemma, as this sector accounts for 50%
of global energy demand and is focused on fossil energy sources that emit
greenhouse gases. This study aims to elucidate the factors preceding engagement in
the energy transition by incumbent oil and gas sector companies, enabling them to
overcome organizational inertia and adopt strategies that lead them to adapt to the
changing global landscape that this sector is undergoing. Through a multi-year
empirical study (2017-2022) and a comprehensive database (168 companies in the
industry), empirical tests were applied to verify the factors preceding incumbent oil
and gas companies engagement. It was seen that the enforcement of the Paris
Agreement, the nature of shareholder control, and the importance of the upstream
segment influence incumbent companies engagement in the oil & gas sector.
