ABSTRACT Following the 2010 Deepwater Horizon (Macondo) oil spill incident it became clear that further focus is required in order to understand and control blowout risks. The control measures are also essential in reducing potential environmental consequences given a blowout event. The latest development in well capping techniques indicates that this might be a viable technical solution for controlling subsea oil and gas well blowouts. The limited field experience with this technology makes it however difficult to presume the effectiveness of the technology as an environmental risk reducing measure. It is assumed that successful implementation of a capping device, given a subsea blowout, would reduce the blowout duration, and thereby limit the total amount of hydrocarbons released into the environment. By combining OPERAto, a dynamic tool for assessing environmental risks from offshore oil and gas activities, and an in-house blowout duration model, the authors have evaluated the use of capping as an environmental risk reduction measure. Uncertainties related to capping used as a solution for subsea blowouts are also discussed.

<p>The majority of the world’s offshore oil and gas structures will need to be decommissioned in upcoming decades as they near the end of their production phase. Once decommissioned, there are three main options available for the now-obsolete structures: complete removal, partial removal, and re-use. Since New Zealand has yet to decommission any offshore structures, there are no past examples or legislative precedent to guide the process. International case studies indicate that social acceptance is crucial to the successful implementation of these projects, so the aim of this thesis was to examine perceptions of different decommissioning options for offshore oil and gas structures in the South Taranaki Bight of New Zealand. Grounded in agenda-setting theory, Study 1 examined the prominence and portrayal of offshore decommissioning in the media. We found an exceedingly low coverage (N = 13) which indicates that the public are likely unaware of the issue. Within the limited sample, the themes 'disregarding decommissioning' and 'addressing decommissioning' were identified which, when combined, suggest that New Zealand is in the pre-planning stage of decommissioning and has yet to explore the options available. Using a postal survey (N = 154), Study 2 measured how the Taranaki community currently understood different decommissioning options, and explored whether and which familiarity variables, psychological constructs, and demographic variables could predict support for different options. The results confirmed a lack of knowledge and awareness (but high levels of interest) among the sample and revealed heterogeneity in which option was supported. Moreover, path analyses showed that awareness, knowledge, age, individualist worldviews, and egalitarian worldviews were significantly associated with support for different options. As will be discussed, these findings have significant implications for communication, engagement, and policy-making in both New Zealand and the international context.</p>

As risk and uncertainty factors have become more prominent in the already volatile energy market because of the COVID-19 pandemic, the development of Arctic hydrocarbon resources has become a debatable issue. At any rate, oil and gas companies need to improve their strategic management systems (along with the development of technologies) for the successful implementation of such complex projects. The purpose of this study was to propose the conceptual basis for transforming strategic management and planning systems of oil and gas companies so that they can successfully face global challenges when implementing offshore oil and gas projects in the Arctic as well as provide more sustainable energy sources. The article discusses the current situation with Arctic initiatives and the results of an analysis of price instability in the energy sector, along with an analysis of several megatrends affecting oil and gas companies. All this allows for presenting a conceptual vision of how a strategic management system should be transformed in order to become able to meet the requirements for implementing Arctic projects, with the emphasis being placed on sustainability, management requirements, and the key principles. The research is based on the fundamentals of strategic management and strategic planning and relies on methods such as desk study, content analysis, event analysis, comparative analysis, and factor analysis.
