Abstract The proportion of hard-to-recover reserves is currently increasing and reached more than 65% of total conventional hydrocarbon reserves. This results in an increasing number of horizontal wells put into operation. When evaluating the resource recovery efficiency in horizontal wells, and, consequently, the effectiveness of the development of gas condensate field, the key task is to evaluate the well productivity. To accomplish this task, it is necessary to obtain the reservoir fluid production profile for each interval. Conventional well logging methods with proven efficiency in vertical wells, in case of horizontal wells, will require costly asset-heavy applications such as coiled tubing, downhole tractors conveying well logging tools, and Y-tool bypass systems if pump is used. In addition, the logging data interpretation in the case of horizontal wells is less reliable due to the multiphase flow and variations of the fluid flow rate. The fluorescent-based nanomaterial production profiling surveillance technology can be used as a viable solution to this problem, which enables cheaper and more effective means of the development of hard-to-recover reserves. This technology assumes that tracers are placed downhole in various forms, such as marker tapes for lower completions, markers in the polymer coating of the proppant used for multi-stage hydraulic fracturing, and markers placed as fluid in fracturing fluid during hydraulic fracturing or acid stimulation during bottom-hole treatment. The fundamental difference between nanomaterial tracers production profiling and traditional logging methods is that the former offers the possibility to monitor the production at frac ports in the well for a long period of time with far less equipment and manpower, reduced costs, and improved HSE.


Significance On the contrary, since May, when the anti-junta National Unity Government (NUG) formed a military wing, fighting has spread nationwide. The most critical arena in the conflict is online space: both sides have effectively weaponised mobile technology and the internet. Impacts Internet shutdowns will impede COVID-19 public health programmes, risking further transmission of infection across borders. International human rights groups will not call for sanctions against tech companies because that would further hinder the opposition. Chinese surveillance technology will be a critical resource for the junta.

Smart health surveillance technology has attracted wide attention between patients and professionals or specialists to provide early detection of critical abnormal situations without the need to be in direct contact with the patient. This paper presents a secure smart monitoring portable multivital signal system based on Internet-of-Things (IoT) technology. The implemented system is designed to measure the key health parameters: heart rate (HR), blood oxygen saturation (SpO2), and body temperature, simultaneously. The captured physiological signals are processed and encrypted using the Advanced Encryption Standard (AES) algorithm before sending them to the cloud. An ESP8266 integrated unit is used for processing, encryption, and providing connectivity to the cloud over Wi-Fi. On the other side, trusted medical organization servers receive and decrypt the measurements and display the values on the monitoring dashboard for the authorized specialists. The proposed system measurements are compared with a number of commercial medical devices. Results demonstrate that the measurements of the proposed system are within the 95% confidence interval. Moreover, Root Mean Squared Error (RMSE), Mean Absolute Error (MAE), and Mean Relative Error (MRE) for the proposed system are calculated as 1.44, 1.12, and 0.012, respectively, for HR, 1.13, 0.92, and 0.009, respectively, for SpO2, and 0.13, 0.11, and 0.003, respectively, for body temperature. These results demonstrate the high accuracy and reliability of the proposed system.

Abstract The value of implementing intervention-less downhole surveillance technology lies in early assessment of field-scale reservoir performance and well deliverability in South Oman's largest waterflood development. Such technology can aid in assessing whether aquifer support by means of (controlled) fracture injection is achievable, which is potentially more valuable than matrix injection to enhance oil production. At the same time HSSE exposure and deferment will be reduced by avoiding well interventions. This paper will share learnings from Distributed Fiber-Optic (FO) Sensing technology. More specifically, this paper will present the case study of field ‘A’, where waterflood is being operated in two methods based on sectors depending on field geological and reservoir properties: ‘Deep’ water injection in the aquifer, under fracture conditions ‘Shallow’ water injection close to the oil-water-contact (OWC), under matrix conditions ‘Deep’ water injection minimizes the risk of early water breakthrough, but it delays the aquifer pressure support which in turn means lower offtake. The ‘Shallow’ water injection (trialed by injecting water 50m below OWC) has a higher risk of water short circuiting, accelerates pressure support and thereby enhances production / well deliverability. Fiber-optic data is part of a decision-based surveillance program, which also included injection / production logging via PLT, step-rate tests, and pressure monitoring. The time-lapse data has illustrated some fracture growth up- and downwards of the perforation interval in most wells but is still contained below the OWC. In some wells, the injection growth is also controlled by the presence of several intra-reservoir shale baffles that are acting as barriers to vertical communication and thereby delaying the injection response while inducing a strong pressure response in nearby producers. The data has helped to further calibrate and validate the model assumptions and will help in optimizing the waterflood development concept for the field. Proactive interventional-less surveillance enables monitoring of the zonal injection conformance, provides advantage of learning reservoir performance and supports agile WRFM operations and decision making. Furthermore, cost competitive and credible technology have made PDO a front runner to keep subsurface risk at as low as reasonably practical levels and boost oil production. This distributed fiber optic sensing technology provided cost-effective, fit-for-purpose, and intervention-less well-and-reservoir surveillance.

Underwater surveillance technology was an advent of the Cold War. This technology saw numerous advancements only once the technology was declassified and pursued by academia. One such advancement in the maritime domain was the development of the Unmanned Underwater Vehicle (UUV) that has the ability to enhance war-fighting capabilities while de-risking human life. Though this technology has since been commercialised, it has found limited takers in the Navy. The limited inroad it has made has been driven primarily by the developers and the governments that fund them. However, since this technology offers numerous benefits to the military it needs to be integrated into the Navy sooner than later. This essentially means that to achieve greater acceptance for naval use/ applications, integrating this technology into the Navy is essential. This in return requires numerous queries to be answered and facts understood to create greater confidence in the technology and its potential. Accordingly, some of these queries that can help address the knowledge gaps to facilitate future acceptance and induction of the UUV technology into the Navy are discussed. Though an attempt to provide comprehensive answers has been made, these answers are not considered complete but only a start point for a debate. As it stands, the technology exists; however, it is a lack of imagination that is disallowing its usage.

Printing companies are commonly SMEs with high flow of materials, which management could be significantly improved through the digitalization. In this study we propose a smart Warehouse 4.0 solution by using QR code, open-source software tools for machine vision and conventional surveillance equipment. Although there have been concerns regarding the usage of QR in logistics, it has shown to be suitable for the particular use-case as pallets are static in the interwarehouse. The reliability of reading of QR codes was achieved by using multiple IP cameras, so that sub-optimal view angle or light reflection is compensated with alternative views. Since surveillance technology and machine vision are constantly evolving and becoming more affordable, we report that more attention needs to be invested into their adaptation to fit the needs and budgets of SMEs, which are the industrial cornerstone in the most developed countries. The demo of proposed solution is available on the public repository https://github.com/ArsoVukicevic/PalletManagement/.

Imagine a world in which each individual has a fundamental right to be reborn. This idle dream haunts Hilde Van Gelder’s associative travelogue that takes Allan Sekula’s sequence Deep Six / Passer au bleu (1996/1998) as a touchstone for a dialogue with more recent artworks zooming in on the borderscape near the Channel Tunnel, such as those by Sylvain George and Bruno Serralongue. Combining ethnography, visual materials, political philosophy, cultural geography, and critical analysis, Ground Sea proceeds through an innovative methodological approach. Inspired by the meandering writings of W.G. Sebald, Javier Marías, and Roland Barthes, Van Gelder develops a style both interdisciplinary and personal. Resolutely opting for an aquatic perspective, Ground Sea offers a powerful meditation on the indifference of an increasingly divided European Union with regard to considerable numbers of persons on the move, who find themselves stranded close to Calais. The contested Strait of Dover becomes a microcosm where our present global challenges of migration, climate change, human rights, and neoliberal surveillance technology converge.
