Classical Oil Country Tubular Goods (OCTG) procurement approach has been practiced in the indus-try with the typical process of setting a quantity level of tubulars ahead of the drilling project, includ-ing contingencies, and delivery to a storage location close to the drilling site. The total cost of owner-ship for a drilling campaign can be reduced in the range of 10-30% related to tubulars across the en-tire supply chain. In recent decades, the strategy of OCTG supply has seen an improvement resulting in significant cost savings by employing the integrated tubular supply chain management. Such method integrates the demand and supply planning of OCTG of several wells in a drilling project and synergize the infor-mation between the pipes manufacturer and drilling operators to optimize the deliveries, minimizing inventory levels and safety stocks. While the capital cost of carrying the inventory of OCTG can be reduced by avoiding the procurement of substantial volume upfront for the entire project, several hidden costs by carrying this inventory can also be minimized. These include storage costs, maintenance costs, and costs associated to stock obsolescence. Digital technologies also simplify the tasks related to the traceability of the tubulars since the release of the pipes from the manufacturing facility to the rig floor. Health, Safety, and Environmental (HSE) risks associated to pipe movements on the rig can be minimized. Pipe-by-pipe traceability provides pipes’ history and their properties on demand. Digitalization of the process has proven to simplify back end administrative tasks. The paper reviews the OCTG supply methods and lays out tangible improvement factors by employ-ing an alternative scheme as discussed in the paper. It also provides an insight on potential cost savings based on the observed and calculated experiences from several operations in the Asia Pacific region.

For S-15 and S-14 wells at South S Field, drilling of the 12-1/4” hole section became the longest tangent hole section interval of both wells. There were several challenges identified where hole problems can occur. The hole problems often occur in the unconsolidated sand layers and porous limestone formation sections of the hole during tripping in/out operations. Most of the hole problems are closely related to the design of the Bottom Hole Assembly (BHA). In many instances, hole problems resulted in significant additional drilling time. As an effort to resolve this issue, a new BHA setup was then designed to enhance the BHA drilling performance and eventually eliminate hole problems while drilling. The basic idea of the enhanced BHA is to provide more annulus clearance and limber BHA. The purpose is to reduce the Equivalent Circulating Density (ECD,) less contact area with formation, and reduce packoff risk while drilling through an unconsolidated section of the rocks. Engineering simulations were conducted to ensure that the enhanced BHA were able to deliver a good drilling performance. As a results, improved drilling performance can be seen on S-14 well which applied the enhanced BHA design. The enhanced BHA was able to drill the 12-1/4” tangent hole section to total depth (TD) with certain drilling parameter. Hole problems were no longer an issue during tripping out/in operation. This improvement led to significant rig time and cost savings of intermediate hole section drilling compared to S-15 well. The new enhanced BHA design has become one of the company’s benchmarks for drilling directional wells in South S Field.

ABSTRACT On July 20, 2012, Heineken, a Dutch brewery offered S$5.125 billion (Singapore dollars; approximately US$4.1 billion) to buy Asia Pacific Breweries Ltd (APB; formerly, Malayan Breweries Limited) from its Singapore-based joint venture partner, Fraser and Neave, Limited. (F&N). At that point, Heineken and F&N had joint control over APB through the joint venture vehicle Asia Pacific Investments Pte Ltd (APIPL). Brewery business under the joint arrangement had moved on quite predictably from the time APB was formed in 1931. However, the calm changed to high drama when Thai Beverage, owned by one of Thailand's tycoons, made a bid for F&N and APB. Heineken was quick to respond by aggressively buying shares of APB, leading to a large control premium being paid in the final offer price. The bidding war was largely motivated by the Dutch and Thai beer giants, each wanting to own the iconic Tiger beer brand that was owned by APB and thus take control of APB's strong market share in the fast-growing market of Asia. The Heineken bid for APB presents an interesting case study regarding the motivations for acquisitions, the nature of control, and accounting for acquisitions. The case also presents rich issues in accounting for changes in ownership interests with and without gain of control.

This paper explores the role of social media in tourist sentiment analysis. To do this, it describes previous studies that have carried out tourist sentiment analysis using social media data, before analyzing changes in tourists’ sentiments and behaviors during the COVID-19 pandemic. In the case study, which focuses on Andalusia, the changes experienced by the tourism sector in the southern Spanish region as a result of the COVID-19 pandemic are assessed using the Andalusian Tourism Situation Survey (ECTA). This information is then compared with data obtained from a sentiment analysis based on the social network Twitter. On the basis of this comparative analysis, the paper concludes that it is possible to identify and classify tourists’ perceptions using sentiment analysis on a mass scale with the help of statistical software (RStudio and Knime). The sentiment analysis using Twitter data correlates with and is supplemented by information from the ECTA survey, with both analyses showing that tourists placed greater value on safety and preferred to travel individually to nearby, less crowded destinations since the pandemic began. Of the two analytical tools, sentiment analysis can be carried out on social media on a continuous basis and offers cost savings.

The article proposes to consider the COVID-19 global pandemic as new major development for cultural industries and policies and to highlight timely and crucial trends due to the lockdown measures. Thus, it attempts to stimulate the scholarship debate regarding the consequences of the pandemic to the action of global online platforms, as well as to policy and economic aspects of cultural sectors. Taking as case study the audio-visual sector, the article explores whether the US global streaming platforms are the winning players of the lockdown measures and emphasizes the multifaceted strategies developed by US-based platforms in order to strengthen their soft power. Focusing on China and the European Union, the article also argues that the overwhelming action of US-based online platforms triggers the potential emergence of media platform regionalization in the context of COVID-19 pandemic. Finally, it highlights the regulatory challenges and how the new empirical trends are expected to shape the current audio-visual policy framework. The analysis focuses on the period between the beginning of global pandemic in Asia-Pacific in January 2020 and the progressive easing of lockdown measures in North America, Europe and Asia-Pacific in July 2020.

The authors present a detailed case study of the evolution of apprenticeships in German banking over the past two decades to analyze why employers continue to be willing to invest in these programs that provide workers with transferable skills. They explain employers' motivation in terms of two “logics.” Some considerations stemming from the logic of consequences, such as recruitment cost savings and enhanced workplace flexibility, encourage retention of the apprenticeship system. On balance, however, the cost calculus that is at the heart of the logic of consequences would, if unopposed, encourage head-hunting for apprentices trained by other firms, eventually undermining the system. The countervailing logic of appropriateness, however, discourages defections from the system by fostering trust among employers, encouraging new firms to participate in the system, supporting the strong reputational effect associated with training, and creating mechanisms with which banks can have a hand in keeping the system efficient.
