Shuaiba formation is one of major oil plays in North Oman and across the region. More than 4 billion barrels in-place oil have been discovered over the past 60 years within Block-6. In the late 90's and early 2000's, the play was thought to be largely creamed and the remaining potential was thought to be trivial and mainly located in areas of low relief which would result in economically challenging discoveries with small volumes.

This pre-conceived view on the Shuaiba play changed with the advent of large 3D wide azimuth (WAZ) seismic data in the last decade linked with large WAZ acquisition campaign in North Oman. In addition, many wells targeting deeper formations penetrated low relief (<15m) Shuaiba structures with encouraging mud gas readings, which when logged found unexpected pay. This together with the advances in seismic processing/imaging and the building of a comprehensive depositional stratigraphic framework led to the proposal of a new stratigraphic play concept in 2020 and was tested with an aggressive exploration and appraisal campaign. The new concept was proven through two discoveries in 2021 delivering attractive recoverable oil volumes which yield high development net present values (NPV) at competitive unit technical costs (UTC). A phased development approach with early monetization of the exploration/appraisal wells is in place for both opportunities supporting PDO's production growth strategy.

With the continued focus in PDO on resilient and attractive projects, Shuaiba as shallow carbonate play will continue to play an important role in sustaining exploration and development activities. To support that and building on the success of this stratigraphic play concept, a Shuaiba play portfolio rejuvenation work was carried out in selected areas resulting in significant recoverable volume addition to the portfolio. These volumes will support the exploration drilling plans in the upcoming 2-3 years. The concept is also being investigated over other white space area's where seismic acquisition or processing is underway. These will further contribute to the future business plan for PDO and Sultanate of Oman.
Challenge of Produced Water Treatment on Offshore Unmanned Wellhead Platform in Aung Sinkha Field
Authors: Jiranoot Suebsook
Published: February 2024

Aung Sinkha (ASK) is a new development field located in the Gulf of Moattama, Myanmar. The two wellhead platforms (WPA-1 and WPA-2) location is 90 km from ASK Onshore Processing Facilities. Based on engineering study and cost evaluation in Conceptual phase, the Produced Water Treatment (PWT) is selected to separate produced water, treat and dispose at offshore wellhead platform. The scope of Basic Engineering (BE) is to design Offshore PWT to achieve disposal specification.

The design challenges of Offshore Unmanned PWT are including various aspects as following.

Extremely varying of produced water profile over the field life Offshore unmanned facilities and locates far from shore Reliability and performance of water treatment Enhancing alternatives of PWT separation efficiency. Produced Water Disposal facilities constraints i.e. Caisson length vs. shallow water depth, Caisson Vent location Layout and structural design to support Water Treatment Package

PWT technology has been evaluated intensively and pre-screened in-house with cost and time constraints prior to preceding Basic Engineering to ensure that all key design parameters are incorporated in the study.

The offshore PWT of ASK is located at WPA-2 with disposal specification less than 29 ppmv of Oil in Water (OIW) as per Myanmar regulation. The primary treatment unit is De-Oiler Hydrocyclone. The secondary treatment unit is Degasser. These technologies are selected as they are mature with proven efficiency, simple control, high reliability of static equipment, fit for purpose to the treatment specification and low investment cost.

The unit is capable to handling wide range of flowrate from 0 to 5,500 BPD with flexible operating and control philosophy. Skim Tank Vessel is installed upstream of PWT Units to ensure stable flowrate enhancing separation performance. To achieve the challenge disposal specification, pressure drop across De-oiler Hydrocyclone and Degasser's retention time are key design parameters. To fill the gap of unmanned operation, OIW at both inlet and outlet stream are online monitoring and operating conditions are remote adjusting. Chemical injection facilities are provided as back-up for separation improvement. For produced water disposal, Caisson length is specially designed for shallow water depth and the dedicated Caisson Vent is required to meet safety design criteria. To be flexible for future de-bottlenecking, the Degasser is designed with provision for upgrading to Horizontal Induced Gas Floatation (IGF).

It is very challenging to achieve water treatment specification steadily with wide range of produced water rate, fluid properties, operating conditions, layout/structural constraints, required high reliability with optimum investment. All aspects and options have been studied and evaluated thoroughly during Basic Engineering in order to accomplish the good design for the first Offshore Unmanned PWT of PTTEP that could be beneficial and applicable to other projects meaningfully.
Quantitative Evaluation and Prevention Technology of Microbiologically Influenced Corrosion Under Deposit in a Middle East Carbonate Oilfield

Published: February 2024

Water flood development mode was adopted to enhance oil recovery in a Middle East carbonate oilfield. The injected water is a mixture from the produced water and clear water. The water quality of the injected water basically meets the requirement standards except that total sulfide content is about 100mg/L. However, the water injection system has still encountered severe microbiologically influenced corrosion perforation and scaling blockage after less than 2 years, which affects the crude oil production in the oilfield.

This paper aims to find out the mechanism of microbiologically influenced corrosion under deposit, and propose the prevention strategy. The maximum likelihood estimation (MPN) and fluorescent staining methods are applied to study the enrichment change of sulfate-reducing bacteria (SRB) under deposit. And then the synergistic effect of scale and SRB on uniform and localized corrosion was quantitatively evaluated using methods such as weight loss test, potentiodynamic polarization curve, white light interferometer, and scanning electron microscopy. On this basis, the electrochemical test and surface analysis methods are used to optimize the integrated inhibitor system for corrosion, scale inhibition, and sterilization.

The results show that the number of SRB under deposit reached the peak value of about 2×108 cells/mL after 7 days, which is nearly one order of magnitude more than the number of SRB floating in the solution. It was clear that SRB is significantly enriched in the deposit. The synergistic effect between deposit and SRB can significantly accelerate the corrosion of carbon steel. The contribution of synergistic effect to uniform corrosion and localized corrosion of carbon steel is as high as 70% and 50% respectively. The synergistic effect of deposit and SRB on corrosion is mainly the promotion of under-deposit corrosion and the acceleration of microbiologically influenced corrosion. The S type small molecular weight corrosion inhibitor and its composite system have excellent anti-corrosion effects under scale, with a corrosion inhibition efficiency of 90%. After on-site application, the corrosion perforation rate is reduced more than 80%.

This study provides useful practical experience to mitigate under-deposit SRB corrosion of high salinity and high acidity water injection systems.
Monetary Reform and Central Bank Digital Currencies: The Impact on Retail Banking
Authors: Abdullah Adam
Published: February 2024

This research aims to clarify the impact of monetary reform on retail banking, with the introduction of private crypto-currencies (CCs) and retail central bank digital currencies (CBDCs). Given the exponential increase in private de-centralized CCs, involving stablecoins and non-backed digital assets, total crypto assets have now developed into a USD 1.04 trillion market capitalization. Governments and monetary authorities were initially reticent, but now a number of central banks are developing their own wholesale and retail CBDCs. By conducting library research, document and content analysis involving secondary data, this research confirms, involving central bank admission, that the current centralized monetary system allows commercial banks to lend the vast majority of deposit money into existence. However, the impact of private CCs and introduction of retail CBDCs will eliminate credit creation, thus rendering the commercial banking model obsolete. This will inevitably involve a structural change in the global financial system, with the separation of the public issuance of money and the private issuance of equity finance and investment. Ultimately, retail CBDCs will have to develop into public stablecoins that are pegged to intrinsic value to satisfy the store of value function of money and provide stability as the common denominator for all economic transactions.

Published: February 2024

This study aimed to determine the factors affecting the capital structure of Islamic banks for a sample of the Middle East for the period 2011-2021. The study used a panel data method by pooling ordinary least squares, fixed effects, and random effects to determine the relationship between book leverage and internal variables such as profitability, size, non-debt tax shield, growth opportunity, tangibility, liquidity, and earnings volatility. The descriptive statistics indicate that Islamic banks are highly leveraged. The results of regression showed that the impact of profitability, size, and growth opportunity is positive on book leverage. In contrast, the results indicated a negative impact of non-debt tax shield and liquidity on book leverage. The results also showed no impact of tangibility and earnings volatility on book leverage. Based on the results, Islamic banks in the Middle East enjoy a special method of choosing capital structure depending on their competitive advantage derived from the concentration of a large proportion of Muslim people dealing with them. Nevertheless, the management of Islamic banks must take the mentioned variables into consideration.
A Case of Autoimmune Metaplastic Atrophic Gastritis with Concurrent Pernicious Anemia and Coombs-Negative Hemolysis
Authors:   Department of Internal Medicine, Harbor-UCLA Medical Center, USA, Marshalek Joseph P
Published: February 2024

Pernicious anemia is an autoimmune disease characterized by atrophic gastritis and vitamin B12 deficiency. Concurrent hemolytic anemia has been described, however its prevalence and mechanism are not well understood. Herein, we present the case of a 40-year-old female who presented with abdominal pain, fatigue, and a 50-lb weight loss over four months. She was found to have macrocytic anemia, leukopenia, moderate neutropenia, and severe vitamin B12 deficiency. Further laboratory testing (indirect hyperbilirubinemia, low haptoglobin, increased lactate dehydrogenase, low reticulocyte index) implied the presence of intravascular hemolysis with a poor bone marrow response. Peripheral blood smear showed hypersegmented neutrophils consistent with megaloblastic anemia and schistocytes suggestive of hemolysis. Notably, the direct Coombs test was negative.The patient’s serum was positive for anti-intrinsic factor and anti-parietal cell antibodies. Esophagogastroduodenoscopy revealed H. Pylori-negative, metaplastic atrophic gastritis with no evidence of malignancy. Thus, a diagnosis of pernicious anemia was confirmed in addition to hemolytic anemia. She was treated with intramuscular cyanocobalamin, resulting in improvement of symptoms, cytopenias, and hemolytic markers. Hemolysis is a rare complication of vitamin B12 deficiency, and multifactorial anemia must always be considered.

Published: February 2024

Selective synthesis of chiral bridged (hetero)bicyclic scaffolds via asymmetric C–H activation constitutes substantial chal-lenges, due to the multiple reactivities of strained bicyclic structures. Herein, we develop the domino transformations through an unprecedent cobalt-catalyzed enantioselective C–H activation/nucleophilic [3+2] annulation with symmetrical bicyclic alkenes. The methods offer straightforward accesses to a wide range of chiral molecules bearing [2.2.1]-bridged bicy-clic cores with four and five consecutive stereocenters in a single step. Two elaborated salicyloxazoline (Salox) ligands were synthesized based on the rational design and mechanistic understanding. The well-defined chiral pockets generated from asymmetric coordination around trivalent cobalt catalyst direct the orientation of bicyclic alkenes, leading to the excellent enantioselectivity.

Published: February 2024

DNA condensates, formed by liquid-liquid phase separation (LLPS), emerge as promising soft matter assemblies for creating artificial cells. The advantages of DNA condensates are their molecular permeability through the surface due to their membrane-less structure and their fluidic property. However, they face challenges in the design of their surface, e.g., unintended fusion and less regulation of permeable molecules. Addressing them, we report surface modification of DNA condensates with DNA origami nanoparticles, employing a Pickering-emulsion strategy. We successfully constructed core-shell structures with DNA origami coatings on DNA condensates and further enhanced the condensate stability toward fusion via connecting DNA origamis by responding to DNA input strands. The ‘armoring’ prevented the fusion of DNA condensates, enabling the formation of multicellular-like structures of DNA condensates. Moreover, the permeability was altered through the state change from coating to armoring the DNA condensates. The armored DNA condensates have significant potential for constructing artificial cells, offering increased surface stability and selective permeability for small molecules while maintaining compartmentalized space and multicellular organization.
Benchmarking water adsorption on metal surfaces with ab-initio molecular dynamics
Authors: Xu Mianle , Liu Sihang , Vijay Sudarshan , Bligaard Thomas , Kastlunger Georg
Published: February 2024

Solid-water interfaces are ubiquitous in nature and technology. Particularly, in technologies evolving in the context of a green transition, such as electrochemistry, the junction of an electrolyte and an electrode is a central part of the device. Simulations based on density functional theory (DFT) have become de facto standard for both the understanding of atomistic processes at this interface and the screening for new materials. Thus, DFT's ability to simulate the solid/water interaction needs to be benchmarked and ideal simulation setups need to be identified, in order to prevent systematic errors. Here, we developed a rigorous sampling protocol for benchmarking the adsorption/desorption strength of water on metallic surfaces against experimental temperature programmed desorption, single crystal adsorption calorimetry and thermal energy atom scattering. We screened DFT's quality on a series of transition metal surfaces, applying three of the most common exchange correlation approximations; PBE-D3, RPBE-D3 and BEEF-vdW. We find that all three XC-functional reflect the pseudo-zeroth order desorption of water rooted in the combination of attractive adsorbate-adsorbate interactions at low coverages and their saturation at intermediate coverage. However, both RPBE-D3 and BEEF-vdW lead to more appropriate water binding strengths, while PBE-D3 clearly overbinds near-surface water. We are able to relate the variations in binding strength to specific variations in water-metal and water-water interactions, highlighting the structural consequences inherent in an uninformed choice of simulation parameters. Our study gives atomistic insight into the complex adsorption equilibrium of water and represents a guideline for future DFT-based simulations of the solvated solid interface within molecular dynamics studies by providing an assessment of systematic errors in specific setups.

Mujeres, consumo de medios y extrema derecha
Authors: García Maseda María , Pereira López María , Vicente Iglesias Gemma
Published: February 2024

Los medios de comunicación proveen de un marco de interpretación de la realidad a la ciudadanía, cuyo consumo tiene, consecuentemente, efectos directos en las actitudes de los ciudadanos, como mecanismo de refuerzo de las convicciones. En el presente trabajo se analiza el papel de las mujeres votantes de VOX en las pasadas elecciones generales de noviembre de 2019 como consumidoras de medios, de forma contrastada con los hábitos de consumo de los hombres. Se busca analizar si realmente existen diferencias en torno tanto a los medios de comunicación que escogen como al uso que hacen de estos. Es por ello que, a partir de los datos del Estudio Postelectoral de las Elecciones Generales en España, noviembre 2019, realizado por el Equipo de Investigaciones Políticas de la Universidad de Santiago de Compostela (EIP-USC), se busca identificar diferencias en las pautas de consumo de medios y motivaciones entre las mujeres y los hombres votantes de extrema derecha. El uso de este estudio se justifica por ser las elecciones en las cuales VOX refuerza considerablemente su presencia en el Parlamento español.

Tantangan Merdeka Belajar secara Daring Menggunakan Metode Resitasi di Masa Pandemi Covid19 Pada Siswa Kelas VIII-DSMP Negeri 4 Tulungagung Semester 2 Tahun Pelajaran 2020/2021
Authors: Prayitno Joko
Published: February 2024

Berdasarkan hasil observasi yang dilakukan di Kelas VIII-D  pada waktu pembelajaran Bahasa Jawa diperoleh hasil bahwa hasil belajar siswa kurang memuaskan, yaitu dari 35 siswa hanya 15 siswa yang nilainya dapat mencapai KKM atau ≥ 72, sedangkan 20 siswa lainnya masih belum dapat mencapai KKM atau ≤ 71.
