Abstract Recent years and especially the coronavirus pandemic have been very challenging for the oil industry, resulting in a significant reduction in investment, forcing companies to review budgets and search for more efficient and economical technologies to achieve the target level of hydrocarbon production and revenue generation. In PDO, one of the most challenging fields is "AS", where extreme downhole conditions require a very well-engineered approach to become economical. This field has already seen some of the most advanced technology trials in PDO that are also covered in multiple SPE papers. Based on the new approaches and techniques that were successfully implemented on recently drilled wells, it was decided to review the older, previously fractured wells in the area and assess them for a refracturing opportunity. The main challenge in this project was that these older wells were previously hydraulically fractured in multiple target intervals, therefore both zonal isolation and successful placement of the new fracs were becoming the major concerns. As the planned coverage by the new fractures was to ensure no bypassed pay, the only applicable technology on the market was a pinpoint fracturing process, whereby the targeted placement is achieved through limited entry perforations and focused energy of the injected fluid. The subject pinpoint technology anticipates that the limited entry sandblasting perforation is created and then proppant laden fluid is pumped through a sandblasting nozzle which is part of either a coiled tubing (CT) or a jointed pipe (JP) Bottom Hole Assembly (BHA), and the backside (or the annulus of the injection path) is used to maintain the positive backpressure from the top. This technology allows for choosing a desirable order of target interval selection inside the well, unlike conventional plug and perf or a simplified multistage completion, where the treatments must be placed only in order from bottom to top. Another advantage of this approach is a faster frac cycle through the elimination of wellbore cleanout requirement. Being a unique and first-ever application in the Middle East, using CT for placing frac treatments through a jetting nozzle demonstrates the full scale potential of this approach not only in conventional wells but also in complex, sour and High Pressure (HP) environments that are often found in the Sultanate of Oman and in the Middle East. This paper will cover the advantages and disadvantages, complexity and requirements, opportunities and lessons learnt in relation to this approach.

Abstract A set of 5 wells were to be drilled with directional Coiled Tubing Drilling (CTD) on the North Slope of Alaska. The particular challenges of these wells were the fact that the desired laterals were targeted to be at least 6000ft long, at a shallow depth. Almost twice the length of laterals that are regularly drilled at deeper depths. The shallow depth meant that 2 of the 5 wells involved a casing exit through 3 casings which had never been attempted before. After drilling, the wells were completed with a slotted liner, run on coiled tubing. This required a very smooth and straight wellbore so that the liner could be run as far as the lateral had been drilled. Various methods were considered to increase lateral reach, including, running an extended reach tool, using friction reducer, increasing the coiled tubing size and using a drilling Bottom Hole Assembly (BHA) that could drill a very straight well path. All of these options were modelled with tubing forces software, and their relative effectiveness was evaluated. The drilling field results easily exceeded the minimum requirements for success. This project demonstrated record breaking lateral lengths, a record length of liner run on coiled tubing in a single run, and a triple casing exit. The data gained from this project can be used to fine-tune the modelling for future work of a similar nature.

Abstract Unconventional reservoir exploration and development activities in the Middle East have increased and are expected to continue to do so. National oil companies in the Middle East have a strategy for maximizing oil exports as well as use of natural gas. This has placed emphasis on use of advanced technology to extend the lives of conventional reservoirs and more activities in terms of “unconventional gas and oil.” Understanding unconventional environments, such as shale reservoirs, requires unique processes and technologies based on reservoir properties for optimum reservoir production and well life. The objective of this study is to provide the systematic work flow to characterize unconventional reservoir formation. This paper discusses detailed laboratory testing to determine geochemical, rock mechanical, and formation fluid properties for reservoir development. Each test is described in addition to its importance to the reservoir study. Geochemical properties, such as total organic carbon (TOC) content to evaluate potential candidates for hydrocarbon, mineralogy to determine the formation type and clay content, and kerogen typing for reservoir maturity. Formation fluid sensitivity, such as acid solubility testing of the formation, capillary suction time testing, and Brinell hardness testing, are characterized to better understand the interaction of various fluids with the formation to help optimize well development. An additional parameter in unconventional reservoirs is to plan ahead when implementing the proper fracturing stimulation technique and treatment design, which requires determining the geomechanical properties of the reservoir as well as the fluid to be used for stimulation. Properties of each reservoir are unique and require unique approaches to design and conduct fracturing solutions. The importance of geomechanical properties is discussed here. This paper can be used to help operators obtain a broad overview of the reservoir to determine the best completion and stimulation approaches for unconventional development.

The Impact

This qualitative short report considers the viability of the use of rubrics or alternative methods to assess writing in Asia and the Middle East. The background of learning theories, assessment types, and self-assessment literature provides a foundation for further discussion of the appropriate use of rubrics, including the prioritization of criterion, the quality of scoring, the impact of organizational features on scoring, the influence of bias, and the best application of rubric assessment. Relevant points for further study are identified, such as differentiation in research between generalized analytical rating systems and rubric assessment with specific, empirical criterion. The contradictory research regarding the advantages and disadvantages of rubric assessment in comparison with holistic assessment are of particular and crucial interest for global pedagogy. Many of the reviewed Western articles excluded Asian perspectives- except for China- and thus present a limited understanding of social and educational compatibility with new assessments and rubric assessments in particular. The discussion identifies patterns and points of contention and seeks to explore viewpoints rather than limit the scope of inquiry and consideration thus noting that relevant literature suggests that with appropriate teacher training, teachers may appropriately use rubrics as a formative assessment tool for writing in Asia and the Middle East.

This article outlines how the rapid evolution of the ICT sector in highly-developed economies has resulted in digital inequality between the EU-15 and countries that joined the EU in the first and second decades of the 21st century. The main hypothesis of the study is that digital inequality be-tween the economies of EU member states weakens the competitiveness of the EU in the area of EU economy 4.0 in the global market and could threaten European digital sovereignty, including the issue of access to public and private data and digital identity protection. The results of the an-alysis show that the currently existing digital inequality widens the digital gap between the EU and the US and China, and further bolsters the digital dominance of non-European countries. The main challenge lies in providing national economies of Central and Eastern Europe with appropriate instruments that would allow them to make up for these digital deficiencies . The study used critical literature analysis and data contained in the reports of the OECD, the International Monetary Fund, the World Bank, UNCTAD, WTO and European Commission materials.

The global market value of control agents used in crop protection and public health is approaching $16 000 million annually, but less than 1% of this market is penetrated by biological control agents (BCAs). This paper examines the suitability of different types of BCA to research and commercialization, bearing in mind the sharply targeted approach employed by much of the industry. Advantages and disadvantages are discussed along with examples of failures and successes with BCAs. Commercialized products described range from specific chemical control agents which have no adverse effects on beneficial organisms to true BCAs such as pheromones, mass-produced bacteria, and predatory mites. From a commercial viewpoint, greatest potential resides with the utilization of bacteria and fungi, particularly for insect control, but registerability (particularly for genetically engineered agents) patentability, reliability and cost-effectiveness must be achieved. Industry believes that biotechnology will increase the usefulness of BCAs and is therefore encouraging cooperation with academic researchers and performing in-house research to advance the technology. Even so, BCAs will not replace chemicals in the foreseeable future, but will complement them and allow the development of improved integrated control measures.

This article describes how U.S. manufacturing was stricken when companies embraced outsourcing beginning in the 1990s as a strategy for taking advantage of lower labor costs in developing countries. The U.S. textile and apparel industries lost 76.5% of its workforce, or 1.2 million jobs, between 1990 and 2012. The catalyst which has renewed the interest in manufacturing textiles and apparel in the United States is the narrowing gap between the U.S. and Asian labor costs. The sector changed in response to technology and the global market, and both the number and type of employees demanded turned as well. The advanced technology currently drives the domestic textile industry. Despite a positive outlook on growth, it is unlikely that textile manufacturing will create the large number of jobs that it did in the past. Furthermore, it is only viable because of the technological improvements to its factories. The current production is designed to employ fewer workers in order be more productive and less dependent on labor costs. Nevertheless, the high demand for specialized and unique textiles in the U.S. and Europe will likely continue to drive improved manufacturing technology and performance. China's transition from a manufacturing economy to a service economy will increase its manufacturing operational costs, while probably growing demand for the sorts of specialized textiles on which American textile manufacturers tend to focus. If such manufacturers can increase their market shares in China and other Asian countries, while maintaining such markets in the U.S. and Europe, the American textile manufacturing industry will likely grow at a moderately high rate.
