Abstract Brazilian Pre-salts fields lie in approximately 2200 m w.d. in a challenging environment and are often characterized by highly corrosive produced fluids that pushed to the extreme the application of the most advanced material technology and engineering. Nevertheless, Lula, Sapinhoá, Mero and Búzios are definitively world-class prospects with production rates that may exceed 30.000 barrels per day per well. The development scheme of the Pre-salt fields followed the experience and the track record of the large number of deepwater fields that were previously developed in Brazil, in the post-salt regions, and is based on satellite wells tied to the floating production platform by means of dedicated production and service risers (i.e. each well has dedicated production and service lines). This satellite configuration offers the advantage to be simple, straightforward and resilient to field layout changes even during the project execution phase. However, the continuous pressure to which the Oil & Gas industry is exposed in order to increase profitability, reduce cost and, more recently, green house gas emission is encouraging Operators to evaluate different field architectures that are more traditionally implemented in other deepwater provinces outside Brazil and that the recent technology and construction asset developments made suitable also for a potential application in the Pre-salt fields. Moreover, those field architectures that are normally based on commingling of wells production are also prone to provide a faster production ramp-up and a reduced time to break even. This paper presents a description of possible Daisy Chain and Manifold-Based subsea architectures that are suitable to be applied to Brazilian pre-salt fields. The pros and cons of these alternative subsea layouts are explored. Additionally, cost and schedule analyses are presented to show the benefits of such architecture regarding CAPEX and ramp-up compared to satellite architecture, considering the "Brazilian pre-salt" scenario. Finally, a generic proposal for subsea architecture is presented for pre-salt developments jointly with practical solutions for typical operation demands related to flow assurance issues like, for instance, wax and hydrate management.

Abstract Integrated operations (IO) is an ongoing change process in the oil and gas industry. New technological opportunities enable working in new ways that involve an integration of onshore and offshore personnel. This paper analyzes the results of two rounds of data gathering in an onshore drilling support center, in terms of the development of resilience. The first round took place in 2004/2005 and the second in 2012. This study presents a framework for the analysis of resilience and has used the case company as a mean of testing the framework. Our findings indicate that the support center has taken a huge step in the direction of becoming more resilient. The drilling company has tested a number of designs and sizes of support centers, each of which has different pros and cons. For the drilling discipline to develop resilience, it is essential that the number of rigs supported by a center is not too large, as they must not become involved in too many rigs and drilling operations. Our findings also indicate that the suggested framework provides a good overall picture of the development of resilience in the case company.

Cloud computing has become an integral part of our daily life and work. In the oil and gas industry, cloud computing is becoming increasingly attractive to experts, operators and software companies. However, we believe there is still some level of mystery for many geoscientists in what cloud computing can actually offer, what the pros and cons are and how it is different to the preceding technologies. We attempt to explain some of the mysteries around the concept of cloud computing and furthermore discuss the benefits and shortcomings of cloud for the oil and gas industry.

The changing environment in an organization is forcing the organization to find a plan of integrated management framework and adequate performance measurement. Failure to plan basically means planning failure for the business. Finding the critical factors of quality management practices (QMP), themediating roles of the contextual factors of world-class performance in operations (i.e., world-class company practices or WCC, operational excellence practices or OE, company nonfinancial performance or CNFP), and the company financial performance would enable the company to facilitate the sustainability of TQM implementation model.This empirical study aims to assess how TQM—a holistic management philosophy initially developed by W. Edward Deming, which integrates improvement strategy, management practices, and organizational performance—is specifically implemented in the oil and gas companies operating in Indonesia. Relevant literature on the TQM, the world-class performance in operations (world-class company and operational performance), the company performance (financial and non-financial performances), and the amendments of the Law of the Republic of Indonesia concerning the oil and gas industry, and related research on how the oil and gas industry in Indonesia develops sustainable competitive advantage and sustainable development programs are reviewed in details in our study. The findings from data analysis provide evidence that there is a strong positive relationship between the critical factors of quality management practices and the company financial performance mediated by the three mediating variables, i.e., world-class company practices, operational excellence practices, and company non-financial performance.

This chapter reports research findings into the productivity challenge facing the Australian oil and gas industry. This industry has been experiencing cost overruns indicating a productivity decline that puts future projects and investment at risk. Using world-class survey methodologies developed by the Centre for Business Research at Cambridge University and adapted for the oil and gas industry, an evidence-based view on business decisions and conditions is provided and linked to performance. While many of the productivity challenges facing the Australian oil and gas industry are beyond immediate managerial control, this research shows that key productivity drivers are in the realm of the firm to influence. The research reported in this chapter shows that improvements in innovation, collaboration, and deeper competitive capabilities are the best levers to lift business productivity and to build a growth pathway for the future for this industry.

Abstract Nigeria has oil and gas as her major source of revenue, accounting for more than 80% of her foreign exchange, with the AfCFTA, that has been signed and ratified not just by Nigeria but by other African countries taking away tariffs on goods and services produced across the continent irrespective of the market where it's been sold. The AfCFTA being the second largest free trade agreement in the history of World Trade Organization is aimed at uniting African markets. This paper aims to review the framework of the continental free trade agreement, it pros and cons, its grey area, and its impact on the Oil and Gas Industry in Nigeria. The impact of the agreement on the local industries servicing the oil and gas industry is considered as well. The paper reviews the possible advantage of the AfCFTA on the Nigerian oil and gas market. The possible threats to nationalization in the oil and gas industry due to the availability of cheap labour and technical expertise across the continent in the country is analyzed. Solutions to protect the oil and gas industry in Nigeria is recommended as well.

Has the industry seen the light on project delivery? Numerous signs of improved execution through the downturn in Australia and across the globe suggest oil and gas companies are finally getting it right after a lengthy period of dismal performance. Even before prices went to US$100 per barrel and beyond, the oil and gas industry had a poor track record of delivering major projects. However, higher prices exacerbated the situation, encouraging poor capital discipline and overconfidence in undertaking large-scale, highly complex projects that overstretched the supply chain. The results were delays, cost overruns and billions of dollars in value destroyed. Over the past decade the average project was delivered 6 months late, with costs up 14% compared with the forecast at final investment decision. The top 15 cost blowouts were a cumulative US$80 billion over budget. Much of that was in Australia. But lessons have been learned. Without the safety net of higher prices, the successful execution of capital projects has become of crucial importance to the industry. There is now evidence of post-downturn projects being delivered on time and on budget; in Australasia, recent examples include Greater Western Flank Phase 2 and the Bayu-Undan infill drilling campaign. But do these successes mean execution has really improved? It can be argued these are relatively simple brownfield, subsea developments. When we enter the next investment cycle with bigger projects (Scarborough, Browse and Barossa), will we see the same old mistakes repeated again?

This essay concisely explains the complex condition of the Venezuelan oil and gas industry and its legal, political, and financial hurdles, exploring what has been the history and context in which the COVID-19 pandemic arrived. Building on a complicated global situation surrounded by the pandemic, it asks and gives answers to: What could be expected to recover an economy dependent on the energy industry, based on an evaluation of legislation in force, its impact on private investments and an appraisal of bills and restructuring projects. Arguments were divided into the current situation, national and international actions for restructuring the oil industry, and the future of the national oil company. The analysis suggests that great changes are necessary for the future of the Venezuelan energy industry with a new public policy agenda mainly driven by private investments, while the energy transition has already started. The conclusion indicates that it is mandatory to assume the recovery of the traditional hydrocarbons sector in Venezuela to point the industry in the transition to decarbonized energy sources, in a world that is struggling with COVID-19.

3D stochastic reservoir modelling is an emerging new technology for the oil and gas industry and is increasingly used by oil and gas companies as a tool to support major business decisions in field development planning, and the acquisition and management of petroleum assets. However, the potential benefit that 3D stochastic reservoir modelling can offer is still overlooked by many asset teams. Conventional methods are often still applied for field development planning and reserve estimation, where over-simplified geological models are used and reservoir uncertainties are substantially under-estimated. This is one reason why the oil and gas industry does not have a good track record in estimating reserves and field development planning.3D stochastic reservoir modelling methods that incorporate the structural-stratigraphic framework, facies and petrophyscial properties can ensure that the reservoir models fully describe reservoir heterogeneity. This in turn lays a sound foundation for field development planning. The 3D stochastic reservoir modelling methods also quantify and reduce uncertainties in various aspects of the reservoir. This allows a field development plan to be more robust yet flexible enough to take the advantage of upside reserve potential and to be economically sound if the downside case occurs. Based on quantification of uncertainties, optimal well positions and well paths can be designed to maximise oil and gas recovery.
