The Stock Market Situation and Economic Growth – An Attempt to Assess the Dependence
Authors: Radke Michał 
Published: December 2021

The aim of the article: The main aim of the article is to analyze the relationship between the stock market situation and the real economy, measured by the strength of the correlation between the rate of return on the stock market and the rate of GDP growth in European capital markets. The next objective is to answer the question whether the stock market index changes are ahead of, and if so, by how much, GDP changes. The author’s hypothesis stipulates that the stock exchange situation precedes the change in economic activity and serves as its forecast.
Methodology: The empirical research work was carried out on the basis of quarterly data value of the stock index and the GDP between 2010 and the first quarter of 2021 for 20 European countries. For indices and GDP, the quarterly dynamics of the rate of return and GDP were calculated. Data on the value of the stock exchange index was taken from the website www.stooq.pl, while data on GDP was taken from Eurostat. Subsequently, the analysis concerned the correlation relationships between the variables on the basis of the Pearson correlation coefficient. The correlation between the variables was calculated without delay, as well as with a delay of one, two or three quarters of the returns on stock indices.
Results of the research: Changes in the value of the stock exchange index is in most cases positively correlated with the change in GDP and the correlation is pronounced, but it is low and moderate. The only market for which a significant correlation was observed, was the Polish market. At the same time, it can be stated that the rates of return on the stock exchange index precede a change in GDP by one or three quarters. No changes were observed for the analyzed countries for two quarters.

Background: Mechanical properties of cell membranes and their structural organization are considered among the most important biological parameters affecting the functional state of the cell. Under the influence of various pathogenic factors, erythrocyte membranes lose their elasticity. The resulting changes in their biomechanical characteristics is an important, but poorly studied topic. It is of interest to study the deformation of native erythrocytes to a depth compatible with their deformation in the bloodstream.Aim: To investigate the patterns of deep deformation and the particulars of structural organization of native erythrocyte membranes before and after their exposure to physicochemical agents in vitro.Materials and methods: Cell morphology, nanostructure characteristics, and membrane deformation of native erythrocytes in a solution of hemoconservative CPD/SAGM were studied with atomic force microscope NTEGRA Prima. Hemin, zinc ions (Zn2+), and ultraviolet (UV) radiation were used as modifiers. To characterize the membrane stiffness, we measured the force curves F(h), hHz (the depth to which the probe immersion is described by interaction with a homogeneous medium), and the Young's modulus values of the erythrocyte membrane.Results: Exposure to hemin, Zn2+ and UV radiation led to transformation of the cell shape, appearance of topological defects and changes in mechanical characteristics of erythrocyte membranes. Under exposure to hemin, Young's modulus increased from 10±4 kPa to 27.2±8.6 kPa (p<0.001), exposure to Zn2+, to 21.4±8.7 kPa (p=0.002), and UV, to 18.8±5.6 kPa (p=0.001). The hHz value was 815±210 nm for the control image and decreased under exposure to hemin to 420±80 nm (p<0.001), Zn2+, to 370±90 nm (p<0.001), and UV, to 614±120 nm (p=0.001).Conclusion: The results obtained contribute to a deeper understanding of interaction between membrane surfaces of native erythrocytes and small vessel walls. They can be useful in clinical medicine as additional characteristics for assessment of the quality of packed red blood cells, as well as serve as a basis for biophysical studies into the mechanisms of action of oxidative processes of various origins.

Quando o funcionamento dos rins é insuficiente para manter a vida, os pacientes com Doença Renal Crônica podem ser submetidos à terapia renal substitutiva. A hemodiálise é uma técnica de purificação extracorpórea que substitui parcialmente algumas das funções dos rins; e que engloba alterações do cotidiano do paciente. Desse modo, a pesquisa busca avaliar o impacto causado pelo processo de hemodiálise em crianças, para elas mesmas e para seus familiares e/ou cuidadores. Trata-se de um estudo secundário e transversal de revisão da literatura utilizando como banco de dados as plataformas da Biblioteca Virtual em Saúde (BVS), PubMed e Scientific Electronic Library Online (SciELO). Foram utilizados os descritores: Diálise Renal e Criança, em todas as plataformas. Seis artigos foram avaliados que tratam sobre o impacto causado pelo processo de hemodiálise. A realização da hemodiálise em pacientes pediátricos representa grande impacto social tanto para os pacientes quanto para seus familiares e/ou cuidadores, que apresentam grau de sobrecarga moderado e índices de depressão e ansiedade maiores do que a população geral.

Effects of sea level and upwelling on development of a Miocene shallow-water tropical carbonate ramp system, Ponce, Puerto Rico
Authors: Ortega-Ariza Diana , Franseen Evan K. , Boudagher-Fadel Marcelle K. 
Published: December 2021

ABSTRACTA Miocene (Langhian–Tortonian, ca. 15–10 Ma) tropical ramp system exposed in southern Puerto Rico is characterized by shallow-water facies consisting of heterozoans, red algae, large benthic foraminifera (LBF), and corals, which occur as isolated corals, segment- and cluster-type reefs, and reworked accumulations. Photozoan association components are limited to corals (Montastraea, Porites, Goniopora, and Agaricia) and LBF (amphisteginids, soritids, gypsinids, miliolids) that have been documented to tolerate elevated nutrients, turbidity, and cooler water conditions. Similar shallow-water carbonate systems are found throughout the Caribbean, and this regional development is thought to have resulted from the well-documented upwelling in the Caribbean during the Miocene. Sea-level fluctuations also exerted a major control on facies distributions and shifts in the Puerto Rico ramp, including a vertical facies pattern that occurs in each of three sequences. Basal parts of sequences, deposited during sea-level rises, are dominantly composed of mollusks, echinoderms, red algae, LBF, bryozoans, and solitary corals that formed in low-energy seagrass-bed environments with local associated higher-energy shoal environments. Coral facies occur only in upper parts of sequences and formed in shallow-water, low- to high-energy environments closely associated with seagrass beds during late highstands and sea-level falls. A similar vertical facies pattern occurs in time-equivalent sequences elsewhere around the Caribbean. Strontium-isotope age data indicate two sequence boundaries reflecting sea-level falls formed at about 12.3 Ma and 11.1 Ma. Correlation with time-equivalent unconformities in other well-dated areas in the Caribbean and to sea-level lows on eustatic curves suggests a global signature for sequence development. The connection between the Caribbean and the Pacific along the Central American Seaway (CAS), impacted by local tectonic episodes and sea-level fluctuations during the Miocene, affected nutrient influx and upwelling in the Caribbean, which may be reflected in the vertical facies pattern in shallow-water carbonate sequences. Times of restricted connection during sea-level falls and lows resulted in reduced nutrients and upwelling, which may have been more conducive to coral development. Time-equivalent tropical carbonate systems in the Mediterranean and Indo-Pacific show similarities to those in the Caribbean, indicating influence of global processes (cooling, temperature gradients, oceanographic circulation). Differences between areas indicates the importance of local and regional controls, which in the Caribbean was dominantly the opening and closure of the CAS.
Aspects of Multiscale Flow Simulation with Potential to Enhance Reservoir Engineering Practice
Authors: Khataniar Sanjoy Kumar , de Brito Dias Daniel , Xu Rong 
Published: December 2021

Summary
A multiscale sequential fully implicit (MS SFI) reservoir simulation method implemented in a commercial simulator is applied to a set of reservoir engineering problems to understand its potential. Our assessment highlights workflows where the approach brings substantial performance advantages and insight generation. The understanding gained during commercialization on approximately 40 real-world models is illustrated through simpler but representative data sets, available in the public domain. The main characteristics of the method and key features of the implementation are briefly discussed. The robust fully implicit (FI) simulation method is used as a benchmark. The implementation of the MS SFI method is found to faithfully reproduce FI results for black-oil problems. We provide evidence and analysis of why the MS SFI approach can achieve high levels of performance and fidelity. The method supports the solution of unique problems that would benefit from incorporating multiscale geology and multiscale flow physics. The MS SFI implementation was used to successfully simulate a typical sector model used for field pilots at extremely high “whole core” scale resolution within a practical time frame leveraging high-performance computing (HPC). This could not be achieved with the FI approach. A combination of MS SFI and HPC offers immense potential to simulate geological models using grids to capture mesoscopic or laminar scale geology. The method, by design, demands fewer computing resources than FI, making it far more cost-effective to use for such high-resolution models. We conclude that the MS SFI method has a distinct capability to enhance reservoir engineering practice in the areas of high-resolution simulation-driven workflows in context of subsurface uncertainty quantification, field development planning, and reservoir performance optimization.

Abstract

Objectives/Scope
To highlight at a high level the successful method of building Continuous Improvement (CI) competence Pan Petroleum Development Oman (PDO) and the different pathways used to engage everyone at every level of the organization circa. 10,000 people as part of PDO transformation to a Continuous Improvement organization

Methods, Procedures, Process
PDO is developing a CI culture through 2 pathways, CI Professional & CI Generalist. CI Professionals, limited to 50 high potentials, spend 3 years full time developing CI competence to a level they can coach autonomously in the business. CI Generalists build CI skills though training and deliberate practice becoming Lean Practitioners, Lean Managers and Practical Problem Solving (PPS) practitioners & facilitators.

Results, Observations, Conclusions
A CI function has been created to own the development of staff, standards, and deployment.
Having quarterly competence development reviews for CI Professionals, to discuss and monitor progress and establish goals for the next quarter have resulted in a step change in speed and quality of development. We have had 100+ CI Coaches through the development program as of July 2021, either returning to the business to germinate CI in their new teams or developing further to become a career CI specialist.
Developing the CI competences for CI Generalist has seen an explosion in ideas circa 10,000 with 500 teams practicing CI Fundamentals, 200+ qualified PPS facilitators & 250+ Lean managers coaching in the business.
Benefits to date include circa 150K M3 production gain and many millions saved from the budget. Observation is we are developing autonomous teams able to solve problems for themselves resulting in an engaged workforce:- Improving today for a better tomorrow.
Sponsorship from the top is the imperative ingredient for success. Engagement of the workforce from the bottom up, staff doing the work, creates the momentum required to make a CI transformation successful.

Novel, Additive Information
Holistically the approach used can be transferred to any other business and although tailored for PDO is business/sector is agnostic. The coaches who have graduated through our internal certification can and are applying Continuous Improvement in our business and externally in other organizations.
Looking to the future we can partner with universities to have Continuous Improvement as part of the curriculum either as modules or a whole syllabus.
The New Edge. Building and Deploying a New State of the Art, High Speed Acquisition, Automation and Analytics Platform for Drilling, Completions, Production, and Renewable Energy Applications
Authors: Pink Anthony Paul , Fehres Carl , Pearce Julie Diane , Costa Stacy , Noworyta Mickey 
Published: December 2021

Abstract
This paper discusses the architecture, development, and deployment of a new state-of-the-art data acquisition and analytics platform. The system is designed to capture and store data for all phases of well construction and is also suited to aggregating data from renewable energy sources such as offshore wind turbines. In today's well construction world it is vitally important that an edge platform can capture high-quality, high-speed data. It needs to be able to universally translate data from many protocols and provide outbound data streams that are easy to consume and store. The high-quality data streams can then be queried by high-value analytics that ultimately deliver predictive and prescriptive solutions.
Our approach was to identify the market pain and develop a system that solved the digital requirements for our customers who needed a field-deployed and field-supported, agnostic digital ecosystem. In the new "Digital Oilfield" the requirements for data capture, aggregation, edge computing, automation, cloud infrastructure and office applications are all expanding rapidly. Most "Edge" solutions are cloud-based and come from purely digital companies who have little or no domain knowledge or field infrastructure with which to deploy and maintain those systems. It was observed that an "Edge" solution was required that remained highly performant even if network connectivity from the cloud to the location was lost.
This paper will also discuss the novel approach to the development of this platform with an oil & gas operator's subject matter experts being embedded in the contractor's product development team. The result being an end-to-end solution designed for both the requirements of the field and the office. The customer had previously built its own system internally, but was looking for a partner who could update and maintain an evergreen technology stack, increase speed and capability and be able to maintain and support a scalable product worldwide on all its operational locations. We will explain the development process, early field testing and commercialization of this product and the results that were achieved. This new system will have an open architecture that allows other digital companies to leverage the high-speed data and host their applications on the platform both on the wellsite and in the office. The system also provides interoperability with the machines on location, this interoperability enables a wide range of 3rd parties to be able to deliver automated applications on the well location. This technology will enable significant performance improvements in drilling and completion operations.

Published: December 2021

Abstract
During open-hole wireline operations, at least 95% of cable sticking events are known to be predictable and avoidable. Approximately 40% of these cable sticking events escalate to fishing operations, adding substantial costs to the AFE. Sub-optimal well design, from a wireline acquisition perspective, is known to contribute to such sticking. This paper offers practical guidance for drilling engineers on how their well designs may impact wireline conveyance and sticking risks and what measures they can take at both the design and execution stages to ensure a safe and efficient wireline logging job.

Abstract
The paper discusses the pilot project in ADNOC Offshore to assess the Autonomous Inflow Control Device (AICD) technology as an effective solution for increasing oil production over the life of the field. High rate of water and gas production in horizontal wells is one of the key problems from the commencement of operation due to the high cost of produced water and gas treatment including several other factors. Early Gas breakthrough in wells can result in shut-in to conserve reservoir energy and to meet the set GOR guidelines. The pilot well was shut-in due to high GOR resulted from the gas breakthrough.
A pilot project was implemented to evaluate the ability of autonomous inflow control technology to manage gas break through early in the life of the well spanned across horizontal wellbore. And also to balance the production influx profile across the entire lateral length and to compensate for the permeability variation and therefore the productivity of each zone. Each compartment in the pilot well was equipped with AICD Screens and Swell-able Packers across horizontal open hole wellbore to evaluate oil production and defer gas breakthrough. Some AICDs were equipped with treatment valve for the compartments that needed acid simulation to enhance the effectiveness of the zone. The selection factors for installing number of production valves in the pilot well per each AICD was based on reservoir and field data. Pre-modeling of the horizontal wellbore section with AICD was performed using commercial simulation software (NETool).
After the first pilot was completed, a detailed technical analysis was conducted and based on the early production results from the pilot well showed that AICD completions effectively managed gas production by delaying the gas break through and restricting gas inflow from the reservoir with significant GOR reduction ±40% compared to baseline production performance data from the open hole without AICD thus increasing oil production. The pilot well performed positively to the AICD completion allowing to produce healthy oil and meeting the guidelines. The early production results are in line with NETool simulation modelling, thereby increasing assurance in the methods employed in designing the AICD completion for the well and candidate selection.
This paper discusses the successful AICD completion installation and production operation in pilot well in ADNOC Offshore to manage GOR and produced the well with healthy oil under the set guidelines. This will enable to re-activate wells shut-in due to GOR constraint to help meeting the sustainable field production target.
Adsorption Inhibitor Role in a Constant Salinity Surfactant-Polymer CSSP Flooding Design for an Offshore Field Application
Authors: Abdul Manap Arif Azhan , Zulkifli Nazliah Nazma 
Published: December 2021

Abstract
A base chemical flooding formulation using alkaline-surfactant-polymer (ASP) has been developed for application in offshore environments. The formulation uses combination of conventional alkali (sodium carbonate) with amphoteric surfactant. The field is currently under waterflooding using sea water as injection water. However, since alkali is incompatible with divalent ions in sea water, an alternative formulation using seawater with no additional water treatment is also being developed and considered for application. The alternative formulation uses combination of alkyl propoxy sulfate (APS) and alkyl ethoxy sulfate (AES). Coreflood recovery performance of both formulations is similar.
Without alkali, high surfactant adsorption becomes major concern for the alternative formulation. Thus, an adsorption inhibitor (AI) agent – polyacrylic acid type, is being considered as an additive to address this concern. While AI showed potential in reducing surfactant adsorption and improving oil recovery efficiency, it can also increase overall cost for the surfactant in sea water chemical formulation. Hence, the merit to apply AI was not clearly observed.
