Offshore Production

The oil and gas industry is headed toward deep water in recent years. Oil companies are seeking new technologies to meet the challenges of deep-water oil exploration and in the near future, this will bring new discoveries. The most difficulty of exploring oil in this region is the depth where the equipment is installed and the production lines must be safe for such activities. Full understanding of the dynamics of the behavior of this equipment is vital to the success of offshore production and operation due to environmental problems that can occur in an accident and a large amount of economic and human resources involved. The phenomenon of the vortex induced vibration (VIV) is complex and involves an interaction between hydrodynamic forces and the response of the structure. The force and displacement can be determined through experimental tests or the complete numerical simulation of the interaction between the structure and fluid. DNV-GL has recently published a guideline about the design of a subsea jumper [1], but it is still needed many studies and experiments to improve the evaluation of VIV in rigid subsea jumpers in the oil industry. The main objective of the present work is to investigate VIV phenomenon in a jumper exposed to uniform flow and verify its oscillation in the flow direction, which called inline VIV (VIVx). Throughout this study, the finite element method was used to perform the structural and modal analysis of the structure, in order to obtain the modes, frequencies and then validate the experimental result. Experimental analysis of jumpers was also performed in a current tank to evaluate the behavior of the jumper with the current flow.

Water Problem

Currently the oil and gas industry is focusing on challenging deep water projects, particularly in Campos Basin located coast off Brazil. However, there are a lot of prolific reservoirs located in shallow water, which need to be developed and they are located in area very far from the coast, where there aren’t pipelines facilities to export oil production, in this case is necessary to use a floating production unit able to storage produced oil, such as a FPSO. So, the riser system configuration should be able to absorb FPSO’s dynamic response due to wave load and avoid damage at touch down zone, in this case is recommended to use compliant riser configuration, such as Lazy Wave, Tethered Wave or Lazy S. In addition to, the proposed FPSO for Tubarão Martelo development is a type VLCC (Very Large Crude Carrier) using external turret moored system, which cause large vertical motion at riser connection and it presents large static offset. Also are expected to install 26 risers and umbilicals hanging off on the turret, this large number of risers and umbilicals has driven the main concerns to clashing and clearance requirement since Lazy-S configuration was adopted. In this paper, some numerical model details and recommendations will be presented, which became a feasible challenging risers system in shallow water. For instance, to solve clashing problem it is strictly recommended for modeling MWA (Mid Water Arch) gutter and bend stiffener at top I-tube interface, this recommendation doesn’t matter in deep water, but for shallow water problem is very important. Also is important to use ballast modules in order to solve clashing problems.

Carbon Economy

Can fossil-based fuels become carbon neutral or carbon negative? The oil and gas industry is facing pressure to decarbonize, and new technologies are allowing companies and experts to imagine lower-carbon fossil fuels as part of a circular carbon economy. This paper draws on interviews with experts, ethnographic observations at carbontech and carbon management events, and interviews with members of the public along a suggested CO2 pipeline route from Iowa to Texas, to explore: What is driving the sociotechnical imaginary of circular fossil carbon among experts, and what are its prospects? How do people living in the landscapes that are expected to provide carbon utilization and removal services understand their desirability and workability? First, the paper examines a contradiction in views of carbon professionals: while experts understand the scale of infrastructure, energy, and capital required to build a circular carbon economy, they face constraints in advocating for policies commensurate with this scale, though they have developed strategies for managing this disconnect. Second, the paper describes views from the land in the central US, surfacing questions about the sustainability of new technologies, the prospect of carbon dioxide pipelines, and the way circular carbon industries could intersect trends of decline in small rural towns. Experts often fail to consider local priorities and expertise, and people in working landscapes may not see the priorities and plans of experts, constituting a “double unseeing.” Robust energy democracy involves not just resistance to dominant imaginaries of circular carbon, but articulation of alternatives. New forms of expert and community collaboration will be key to transcending this double unseeing and furthering energy democracy.

Abstract Historically, the oil and gas industry has been slow and extremely cautious to adopt emerging technologies. But in the Age of Artificial Intelligence (AI), the industry has broken from tradition. It has not only embraced AI; it is leading the pack. AI has not only changed what it now means to work in the oil industry, it has changed how companies create, capture, and deliver value. Thanks, or no thanks to automation, traditional oil industry skills and talents are now being threatened, and in most cases, rendered obsolete. Oil and gas industry day-to-day work is progressively gravitating towards software and algorithms, and today’s workers are resigning themselves to the fact that computers and robots will one day "take over" and do much of their work. The adoption of AI and how it might affect career prospects is currently causing a lot of anxiety among industry professionals. This paper details how artificial intelligence, automation, and robotics has redefined what it now means to work in the oil industry, as well as the new challenges and responsibilities that the AI revolution presents. It takes a deep-dive into human-robot interaction, and underscores what AI can, and cannot do. It also identifies several traditional oilfield positions that have become endangered by automation, addresses the premonitions of professionals in these endangered roles, and lays out a roadmap on how to survive and thrive in a digitally transformed world. The future of work is evolving, and new technologies are changing how talent is acquired, developed, and retained. That robots will someday "take our jobs" is not an impossible possibility. It is more of a reality than an exaggeration. Automation in the oil industry has achieved outcomes that go beyond human capabilities. In fact, the odds are overwhelming that AI that functions at a comparable level to humans will soon become ubiquitous in the industry. The big question is: How long will it take? The oil industry of the future will not need large office complexes or a large workforce. Most of the work will be automated. Drilling rigs, production platforms, refineries, and petrochemical plants will not go away, but how work is done at these locations will be totally different. While the industry will never entirely lose its human touch, AI will be the foundation of the workforce of the future. How we react to the AI revolution today will shape the industry for generations to come. What should we do when AI changes our job functions and workforce? Should we be training AI, or should we be training humans?

The Impact

Since the beginning of the 19th century, we have assisted major proliferation of the oil and gas industry. This phenomenon of exponential growth is due to the fact that oil companies hold the world’s oil monopoly on the extraction, processing and commercialization. Therefore, as being one of the most influential sectors in the world, is crucial to strictly regulate how oil and gas contracts concerns the potential environmental and social impacts arising from the conduct of petroleum operations and how such behavior affects the human rights. As a matter of fact, the social issues field is an emerging area, and despite such importance, oil contracts do not often deal with them in great detail, corresponding to an actual emptiness of the human rights provisions. In terms of responsibly, oil companies, have an inalienable obligation to ensure that their actions do not violate human rights or contribute for their violation. This study aims to trace a detailed analysis of the impact of the oil and gas agreements in human rights. In order to fully comprehend the deep effects of this industry, we will examine, in detail, numerous of published oil and gas agreements, as well as, decode which are the real standards and practices accepted by this industry. We will use a deductive and speculative reasoning. We will try to demonstrate how incipient and short protection is given to human rights and what responsible conducts must urgently be developed.

The author studies environmental insurance in nature management as a lever of management measures to prevent and eliminate environmental pollution by oil products during their transportation and oil fields development. The research aims to develop recommendations for environmental risks insurance in Russian oil and gas industry on the basis of economic and mathematical model that allows to estimate the scale of environmental pollution by oil products. Such methods as system and comparative analysis, expert assessments, forecasting, modeling used in this work helped the author to identify Russian environmental insurance features; to propose a method for solving the problem concerning the lack of statistical data on the frequency and scale of accidents and the environmental damage magnitude by mathematical modeling of the accident, which allows to estimate the radius and depth of the underlying surface pollution. These developments will help insurers to make more adequate insurance premiums and tariffs, as well as to improve the underwriting procedure for unique oil and gas projects. But in order for the obtained achievements to find their application, it is necessary to have legislation obliging oil companies to compensate for environmental damage, and due to the scale of such damage, oil companies will be obliged to insure the relevant risks.

In recent years, Australia has gone through an unprecedented expansion in its oil and gas industry. The demand for capital has been enormous and has resulted in some of the largest project debt financings globally. In the coming years, the funding requirement will change dramatically as projects reach completion; become cash-flow positive; and, owners changing their funding structure from project finance debt to lower cost, lower covenant corporate debt. The development of a number of Australia’s largest oil and gas projects during the past five years coincided with a tightening of capital from the traditional project finance market. This lead to the emergence of export credit agency financing as an integral component of project development. During the past year, however, re-capitalisation of global banks are now re-entering the Australian market and are driving competition and increasing liquidity. This extended abstract covers a review of the funding approaches taken on major Australian LNG projects, including lessons from the funding of CSG projects that may be relevant to other new development markets such as shale gas. It also draws on historical lessons of funding new technologies and provide insight about funding of the next wave of LNG development: floating LNG. The National Australia Bank is one of the largest resources project finance banks globally and is well positioned to provide APPEA’s delegates with relevant insight about the future of debt funding in the oil and gas industry.

Stress Concentration Factors

Abstract In the oil and gas industry, fixed platforms are commonly applied in shallow water production. In-place environmental conditions generates cyclic loads on the structure that might lead to structural degradation due to fatigue damage. Fatigue is one of the most common failure modes of offshore structures and is typically estimated when dimensioning of the structure during design phase. However, in times when life extension of existing offshore structures is being a topic in high demand by industry, mature fields may represent an interesting investment, especially for small companies. Concerning fixed platforms, composed mainly by welded tubular joints, the assessment of hot spot stresses is considered to predict structure fatigue. The estimation of welded joint hot spot stresses is based on the stress concentration factors (SCFs), which are given by parametric formulae, finite element analysis (FEA) or experimental tests. Parametric formulae may be defined as a fast and low-cost method, meanwhile finite elements analysis may be time consuming and experimental tests associated with higher costs. Given these different characteristics, each method is applied according to the study case, which will rely on the joint geometry and associated loads. Considering simple joint geometries several sets of parametric equations found in the literature may be applied. On the other hand, the SCFs calculation of non-studied yet complex joints consider known formulae adapted according to the under load joint behavior and geometry. Previous analysis shows that this adaptation may furnish different results compared to those obtained by FEA. Furthermore, it is observed that even for simple joints the results derived from the different methods may differ. Given their importance for the oil and gas industry, since they are the basis for the assessment of the fatigue life of welded tubular joints which may impact on additional costs related to maintenance and inspection campaigns, the estimation of SCFs must be the most accurate as possible. Therefore, this paper intends to investigate the differences between results derived from parametric formulae and different FEA studies.

Since 1996, Petróleo Brasileiro S.A. – Petrobras, the biggest oil company in Latin America, has been supporting a programme for the design, customization, and implementation of tri-lateral collaborative arrangements called the Centres and Networks of Excellence (CNE) Programme, in areas which are critical to the company's competitiveness. This programme is aligned with the Open Innovation proposal, as it is designed to intensify the inflows and outflows of information and technology, from internal and external sources, in the RD&I activities of the participating organizations. This article presents qualitative research based on the case study of the Centre of Excellence (CE) in Engineering, Procurement and Construction (EPC), a hybrid organization which brings together oil companies, EPC companies, universities and technical schools, government entities, professional associations and industry bodies, in an effort to make the Brazilian EPC sector related to the oil and gas industry sustainable and competitive worldwide. The principal objective was to investigate the governance elements and managerial mechanisms that support or hinder collaboration among the parties. The work included the identification of collaborative activities within the organization and aspects of trust. Qualitative data was collected by means of in-depth interviews with staff and executive members of the CE-EPC. The case study highlighted the potential of the method to help set up hybrid collaborative initiatives among parties from different institutional spheres. However, the research identified some barriers to the full accomplishment of CNE. A weak culture of collaboration was the greatest difficulty found in the CE-EPC case. The lack of positive previous cooperation experiences together with a lifelong practice of market relations make it hard to get members to focus attention on a new work logic. Yet, despite the high asymmetry among members and the weak network culture, the results indicate that the CE-EPC has accomplished significant positive results in twenty months of operation and that its internal environment is supportive and favours the improvement and consolidation of the organization.
