Abstract The COVID-19 pandemic brought with it the potential risk for personnel abandonment of various oil and gas installations that was unprecedented in the industry. Uncertainties on how to implement and monitor these processes was a significant challenge. This pandemic scenario required that operators and regulators work together to reformulate their normal way of working to decrease the risk of virus exposure to personnel, while still ensuring critical elements were implemented for safe operations. Regulators were required to act quickly to implement and adjust regulations to meet the new demands for safe operations during the global pandemic. Through joint discussions with industry associations and an understanding of the situation, the Brazilian oil and gas industry regulator, ANP, was able to immediately implement tracking requirements and, within less than one month after formal declaration of a state of emergency, issued new regulations for the restart and operations of installations. These measures assisted in a better understanding of the COVID-19 situation onboard offshore installations and in disseminating learnings across Exploration and Production (E&P) industry. Operators across Brazil all implemented modified emergency response plans, new hazard identification measures and means to reduce the risks of these identified hazards in response to COVID-19. The ANP worked to oversee the manner in which these measures were conducted, while successfully assisting in reducing demands on offshore work during the pandemic by migrating to a fully-remote means of regulatory enforcement and auditing. Regulators and operators all worked across five key areas and within the joint efforts significantly mitigated the impacts which COVID-19 had on the industry in Brazil. These key areas were: Operational Safety Documentation, procedures within the regulations and management system to cope with the pandemic scenario; Tracking of COVID-19 cases and effective response measures/learnings across industry; Hazard Identification related to the operational conditions impacted by the COVID-19 crisis; Risk Assessment for the identified hazards because of the pandemic; and Emergency Response plans for response to the worst-case operational scenario during a pandemic. Although severe outbreaks did occur on several installations, causing temporary shutdowns, there have to date been no major operational accidents as a result of COVID-19 personnel evacuations or procedures. Additionally, the total oil and gas production levels for Brazil have been maintained or increased across the sector. These high-level performance indicators demonstrate that through the efforts of the ANP, operators, service providers and other regulators, the pandemic situation is being managed successfully while the industry also continues meet the necessary energy demands of the country. Although the global pandemic has been a sobering and dark period in history for all, there have been positive outcomes for the oil and gas exploration and production industry. The three most apparent positive outcomes are: Ability of regulators and operators to adapt together; A focus by all players on the safety of the workforce and environment;. Effectively operating under adverse conditions with reduced and essential workforce.

Slug flow in horizontal pipelines and riser systems in deep sea has been proved as one of the challenging flow assurance issues. Large and fluctuating gas/liquid rates can severely reduce production and, in the worst case, shut down, depressurization or damage topside equipment, such as separator, vessels and compressors. Previous studies are primarily based on experimental investigations of fluid properties with air/water as working media in considerably scaled down model pipes, and the results cannot be simply extrapolated to full scale due to the significant difference in Reynolds number and other fluid conditions. In this paper, the focus is on utilizing practical shape of pipe, working conditions and fluid data for simulation and data analysis. The study aims to investigate the transient multiphase slug flow in subsea oil and gas production based on the field data, using numerical model developed by simulator OLGA and data analysis. As the first step, cases with field data have been modelled using OLGA and validated by comparing with the results obtained using PIPESYS in steady state analysis. Then, a numerical model to predict slugging flow characteristics under transient state in pipeline and riser system was set up using multiphase flow simulator OLGA. One of the highlights of the present study is the new transient model developed by OLGA with an added capacity of newly developed thermal model programmed with MATLAB in order to represent the large variable temperature distribution of the riser in deep water condition. The slug characteristics in pipelines and temperature distribution of riser are analyzed under the different temperature gradients along the water depth. Finally, the depressurization during a shut-down and then restart procedure considering hydrate formation checking is simulated. Furthermore, slug length, pressure drop and liquid hold up in the riser are predicted under the realistic field development scenarios.

Nanotechnology encompasses the science and technology of objects with sizes ranging from 1 nm to 100 nm. Today, exploration and production from conventional oil and gas wells have reached a stage of depletion. Newer technologies have been developed to address this problem. Maximum oil production at a minimum cost is currently a huge challenge. This paper reviews nanotechnology applications in the oil and gas production sector, including in the fields of exploration, drilling, production, and waste management in oil fields, as well as their environmental concerns. The paper reviews experimental observations carried out by various researchers in these fields. The effect of various nanoparticles, such as titanium oxide, magnesium oxide, zinc oxide, copper oxide, and carbon nanotubes in drilling fluids and silica nanoparticles in enhanced oil recovery, has been observed and studied. This paper gives a detailed review of the benefits of nanotechnology in oil exploration and production. The fusion of nanotechnology and petroleum technology can result in great benefits. The physics and chemistry of nanoparticles and nanostructures are very new to petroleum technology. Due to the greater risk associated with adapting new technology, nanotechnology has been slow to gain widespread acceptance in the oil and gas industries. However, the current economic conditions have become a driving force for newer technologies.

Government policies in natural resource management, especially in the oil and gas sector face a lot of problems. However, the government also has a responsibility to improve the life of people affected from oil and gas exploration and production activities. This research was aimed at investigating how the implementation of policies run by the central and local government toward the oil and gas management and community empowerment, especially the community located closely  to oil and gas exploration and production activity in Madura, East Java. This research method is phenomenological research using descriptive qualitative approach. Therefore, this study is conducted through direct observation on the object during the research time. The data collection is done through observation and interview. The results of this study revealed that it is needed an integrated step done by the government, vertically, whether central, provincial, district, and village to synchronize oil and gas management and community empowerment programs. By doing so, the ideas and desires to improve the welfare and increase the state income will be realized, especially in focusing corporate and government programs improving citizen’ economic and education, whose area becomes the location of oil and gas production.

Developing skilled petro-technical professionals (PTPs) has the greatest lead-time of any activity that oil and gas companies undertake today. Australia could double its gas production by 2020, which would create 50,000 new jobs. This will intensify competition for skilled petrotechnical professionals, and may drive up people costs. The market for PTPs in Australia is tight today, with active competition for technical talent between the oil and gas industry and other extractive industries. Conventional and unconventional oil and gas projects on Australia’s west and east coasts are already chasing the same, limited, talent pool. Competition for experienced PTPs will be intensified by the impending crew change, with a disproportionate number of experienced PTPs due to retire from Australia’s oil and gas industry over the next decade. Schlumberger Business Consulting has been benchmarking the people situation in the global oil and gas industry for the past six years, and working with exploration and production companies to address it. This paper will present our analysis of the global, and Australian, situation, with quantification of the skill balance through our demand and supply model. It will also highlight specific technical skills that will be in short supply, implications of the skills shortage, as well as potential mitigations to create competitive advantage.


Subject Gas sector update. Significance Despite sharp reductions in oil companies' global exploration and production, Egypt is attracting multi-billion-dollar fast-track upstream oil and gas investment. Cairo has already made progress in addressing key imbalances in its energy sector, and succeeded in reducing arrears to oil companies. Boosting upstream oil and gas production will eventually help stabilise the budget. Impacts Egypt's gas balance could turn positive by 2020, reducing the country's demand for LNG and oil product imports. Incentives for renewables, particularly solar power, are a likely path for diversifying the energy mix and stemming domestic gas demand. The government is likely to remain committed to generous PSAs. It will also probably advance domestic gas pricing reform to maintain the upstream sector's current momentum.

For more than a decade, Spar Top Tension Risers (TTRs) and Steel Catenary Risers (SCRs) have established a good track record through technology innovations. This paper describes how Spar TTR and SCR riser configurations have evolved to meet increasing industry demands and discusses the future of these riser systems. TTRs on the first Spar, Neptune, installed in the GOM in 1996, were supported by buoyancy cans. The next several Spar risers also used buoyancy cans with various improvements and modifications to the buoyancy can system design and installation method. In 2003, BP’s Holstein Spar was the first to use hydro-pneumatic tensioners to support its TTRs. The Kikeh and Perdido Spars also used tensioners. Optimization of TTRs is continuing with new construction methods such as the use of threaded and coupled (T&C) connectors instead of weld-on threaded connectors. Spar SCRs have also received widespread acceptance for deep and ultra-deepwater oil and gas production in recent years. The SCR has the advantages of relative low cost, conceptual simplicity, ease of fabrication and offshore installation. SCR hang-off options on a Spar include porch and pull tube. The pull tube option provides the most efficient technical solution for installation, brings the SCR interface above the water, which facilitates the piping hookup, and is better suited for the Spar’s architecture and transportation method. SCRs supported from a Spar have good fatigue performance in the touchdown region due to the relatively low motions of the Spar. As exploration and production activities move into deep and ultra-deepwater, and the metocean data increases in severity, Spar risers face additional design and analysis challenges. Adoption of high strength materials and strain-based design to meet these challenges is discussed.

Oil and gas exploration and production are two of the activities that potentially cause pollution and environmental damage. The largest waste generated from this activity is produced water. Produced water contains hazardous pollutants of both organic and inorganic materials, so that the produced water of oil and gas production cannot be discharged directly to the environment. Uncontrolled discharge can lead to the environmental damage, killing the life of water and plants. The produced water needs to be handled and fulfill the quality standards before being discharged to the environment. Several studies to reduce the contaminants in the produced water were conducted by researchers. Among them were gravity based separation - flotation, separation technique based on filtration, and biological process treatment. Therefore, some of these methods can be used as an alternative waste handling of produced water.

As an oil producing nation, Indonesia embodied its authority to manage its oil resources through article 33 paragraphs 3 of The Republic of Indonesia Constitution 1945. Regarding the article, this means that the state has the authority to manage Indonesian natural resources, directly or indirectly, through other public and/or private institutions and the profit of such activity shall be for the benefit of the people. This granted the state to appoint other institution, including a National/International Oil Company (NOC/IOC), to manage the exploration and production of oil, as that particular activity is regarded as a high risk and high capital business. In order to do so, according to Law no. 22 2001, the state may appoint a NOC/IOC through a production sharing contract. In this research, it is founded that the regulation that governed a production sharing contract with the gross split mechanism—Ministry of Energy and Mineral Resources Regulation No. 8 2017 jo. Ministry of Energy and Mineral Resources No. 52 2017—does not have a strong legal basis. In overall, the management of oil and gas through the gross split mechanism does not gives a maximum benefit for the state, and does not attract the IOC/NOC interest to explore and produce oil and gas in Indonesia. Therefore, in this paper, the reviewing of oil and gas management through a gross split mechanism is recommended. Keywords: management, gross split scheme, income taxes
