Ria Ricis and New Platform of Islamic Popular Culture
Authors: Akmaliah Wahyudi 
Published: January 2020

Not only change the landscape of popular culture, but the presence of social media also reshapes the structure and the agency. Nowadays, social media can turn ordinary people to celebrities. Using Instagram and YouTube, Ria Ricis has become a piety celebrity who shows her Islamic identity through Islamic performance by wearing the veil in a casual way and earns money from her uploaded videos in social media. Based on a case study of this figure, this paper raises questions related to Islamic popular culture in Indonesia: How does Indonesian define their public sphere currently amid the growth of social media usage? How does Indonesian Muslim respond to social media as a part of digital technology amidst Islamization in the post of an authoritarian regime? What is the possibility of tension for that young Indonesian Muslim as micro-celebrity while facing the three factors related, Islamic identities, enjoyment, and economic benefits? This paper argues that the new media platform has not only affected Indonesian Muslimsâ€™ lifestyles, but also the way in which they negotiate Islamic values, secular life, and economic interest.Â Keywords: Ria Ricis, Social Media, Islamic Popular Culture, and Digital Economy
Competing Identity and Culture: The Formation of Forum Lingkar Pena and Komunitas Matapena in Indonesia
Authors: Ismah Nor 
Published: January 2020

This study focusses on the genealogy of the Forum Lingkar Pena and Komunitas Matapena movements, which have produced novel Islam remaja (Islamic youth novels) and novel pop pesantren (pesantren popular novels). Using Bourdieuâ€™s concept of habitus, I analyze the field where Forum Lingkar Pena and Komunitas Matapena discourses are disseminated, particularly among Muslim youth in Indonesia and how Islamic popular culture is represented through these novels and the dynamic of youth Muslimsâ€™ community struggle for meaning in the Indonesian literary field in general. This research found that establishment of FLP and Komunitas Matapena can be described through three main ideas. Firstly, these communities encountered the massiveness of popular culture by offering a medium that supports identity formation for Muslim youth. Secondly, there is a link between the idealism promoted by Muslim organization movements and the establishment of FLP and Komunitas Matapena, and this link determines their forms and cultural products. Thirdly, they use popular culture, such as magazines and popular novels, as media to spread and preserve their idealism, targeting young people.Â Keyword: Islamic youth, FLP, habitus, popular culture, identity

Authors: Vass Sándor , Zöldy Máté 
Published: January 2020

Abstract
This work is about the validation of a Common Rail (CR) injector model. The model describes injector internal behavior in a detailed way, validation is done using dosage measurements and needle lift traces.
The model contains fluid dynamic, mechanic and electro-magnetic parts describing all important internal processes. To compare the modelling results against measurement data, three test cases were chosen on a medium duty test engine to represent a wide range of operation points. Dosage measurements were done by averaging the injected mass of 1500 injections, each measurement repeated three times. Needle displacement was measured using an injector equipped with a needle lift sensor in the same operating points. The results of the simulated injector and the measured values showed good conformity both in needle displacement and injected fuel mass, so the model can be a basis for further injector and combustion analyses.

Authors: Merah Abdelkrim , Kelaiaia Ridha , Mokhtari Faiza 
Published: January 2020

Abstract
The Taylor-Couette flow between two rotating coaxial cylinders remains an ideal tool for understanding the mechanism of the transition from laminar to turbulent regime in rotating flow for the scientific community. We present for different Taylor numbers a set of three-dimensional numerical investigations of the stability and transition from Couette flow to Taylor vortex regime of a viscous incompressible fluid (liquid sodium) between two concentric cylinders with the inner one rotating and the outer one at rest. We seek the onset of the first instability and we compare the obtained results for different velocity rates. We calculate the corresponding Taylor number in order to show its effect on flow patterns and pressure field.

Feminization of Higher Education in Poland in 1918-2018
Authors: Popiński Krzysztof 
Published: January 2020

Abstract
The text is devoted to women’s presence in the Polish higher education in 1918-2018. Its history is presented in chronological-thematic order, including information about the beginnings of women’s studies at universities as well as their basic political, economic and cultural conditioning. Although during the discussed period, basis of political system in Poland changed three times, there was a constant development of the size of higher education, as well as an increase of women’s participation among students and academic faculty. The beginnings were very modest. However, today women constitute already the majority of students of higher education and almost a half of academic employees. Women, during their fight for equality in access to studies and academic career, had to overcome many legal obstacles, also informal ones, resulting from vitality of the image of traditional social role of women. Even though, the formal equality was gradually earned, it is still more difficult for women than for men to undertake studies at some faculties, and to get higher degrees and academic positions as fast as men.

Solving Overburden Anomalies with Depth Imaging in Conjunction with Customized De-Multiple Flow in a Carbonate Field Offshore Abu Dhabi
Authors: Xu Zuo , Mills Keith , Cooper Sharon , Cordery Mike , Shimoju Ryo , Kleef Franciscus Van , Waqas Muhammad 
Published: January 2020

The seismic imaging of carbonate fields offshore Abu Dhabi is complicated by shallow overburden anomalies (e.g. channels, sink holes, karst features, etc.), strong anisotropy and complex multiple generation mechanisms. Noisy data and converted wave energy create further difficulties. All of these pose challenges for conventional time imaging (PreSTM), resulting in structural uncertainty and unreliable reservoir characterization.
Successful imaging requires an accurate velocity model. This is important in the shallow overburden area where inaccurately modelled localized anomalies will amplify errors to deeper targets as waves pass through them, creating artificial pull-ups and push-downs.
Seismic anisotropy has a key role in accurate subsurface imaging. In this region, anisotropy is complicated, with values ranging from negative delta to large positive epsilon. Inaccurately estimated anisotropy will result in over compensated velocities, and may cause cycle-skipping in diving-wave Full Waveform Inversion (FWI).
Shallow water topography and strong impedance contrasts in the area lead to a substantial amount of free-surface and inter-bed multiples. The repetitiveness of the flat mega-scale geology makes it difficult to distinguish and attenuate multiples from primaries.
In this paper, we demonstrate that extensive pre-stack depth migration (PreSDM) technologies including Dip Constraint Tomography (DCT), Structural Constraint Tomography (SCT), Vertical Seismic Profile (VSP) constraint anisotropy update and a well-designed de-multiple flow can successfully resolve the challenges mentioned above.

Published: January 2020

This paper highlights several opportunities to maximize the total crude oil yield of typical Gas Oil Separation Plants (GOSP's), gas handling and crude oil stabilization systems. This can be achieved for existing facilities by optimizing operating parameters without capital cost or plant modification. Maximizing GOSP's yield (oil recovery) has many advantages such as revenue generation, reducing energy requirements of associated gas handling, mitigating export gas transportation challenges as well as reducing capital cost for new facilities.
Throughout three case studies, this paper demonstrates the impact of operating parameters change in reducing GOSP's total oil shrinkage:
Case Study-1: Pressure let-down optimization of multistage separation
Case Study-2: Temperature optimization of compressors after-coolers
Case Study-3: Temperature optimization of crude stabilization
The analysis was performed for each case study utilizing HYSYS process simulation to establish the optimum operating window for the subject process area. The theoretical results were advanced by conducted field trials under governing operating procedures to validate the conclusion and further explore the benefits as well as the potential challenges of these opportunities.
In case study 1, for high GOR GOSP where more than 3 stages of pressure letdown are required, pressure optimization of the intermediate and low pressure gas/oil separation stages achieved an oil output increase of 3.5 MBD for the same base rate (500 MBD) with dropping gas compression power requirement by 10 MW.
In case study 2, for GOSP's where steady-state hydrocarbon condensate recovered from compressors after coolers knock-out drums is spiked into main Light crude production, optimizing air coolers operating conditions result in a gain of up to 2 MBD in export oil for the same base rate (200 MBD). Moreover, 50% drop in export gas water load can be achieved which helps mitigating pipeline corrosion challenges in gas transportation given the unavailability of a gas dehydration system in the facility.
In case study 3, optimizing inlet temperature of light crude stabilizer enhanced column stripping capability and enabled meeting the required H2S and vapor pressure specification with minimum hydrocarbon liquids losses. A Reduction of 20 °F in inlet temperature resulted in savings of up to 2 MBD stock tank crude for the same base rate of 500 MBD in the expense of reboiler's duty.

Authors: Nugraha Budhi , Nair Ragesh , Muhammad Kashif 
Published: January 2020

High-quality and completeness of real time drilling data have become critical factors to capitalize the improvement of data analysis for decision making. This paper proposes a combined architecture that supports edge computing technology with high frequency real time data to produce smart alerts as well as for the remote monitoring of real time data status for large number of rigs in a centralized location to enhance the surveillance of real time drilling data transfers.
Unlike the traditional real time data surveillance method that monitors the data in the WITSML town server, this innovative technique analyzes the real time data quality right on the edge device. It offers smart computation to produce rule-based intelligent alarms for effective decision-making. This method delivers flexibility and effectiveness in WITSML real time data monitoring as it is fully independent from direct access to the WITSML Store. The biggest advantage of this approach is that it handles the remote surveillance of numerous rigs and gives absolute control over data aggregation.
Managing sensitive drilling data has started to play a key role in cost optimization and critical decision- making, especially when running an active mission critical operation. The new approach of edge computing to analyze the WITSML data from its activity file at the rig site is a breakthrough in the real time data monitoring concept. A rule-based smart alarm system to check the statistics of real time data on the edge increases the confidence of the decision-making process as any data transfer issue can be detected faster. Further analysis and active monitoring of multiple rigs data transmission can be done by a centralized control panel, accessed from the real time operations center in town. Having a system with a precise method to actively monitor the status of real time data transfers on multiple rig sites and smartly generate alerts, assures end users to manage their well efficiently.
Emphasizing the requirement to ensure the nature, quality and latency of real time information at rig site will reduce the lost and non-productive time overall.
Extending Salinity Operating Range and Water Detection Lower Limit of Multiphase Flowmeters
Authors: Fiore Massimiliano , Xie Cheng-Gang , Jolivet Guillaume 
Published: January 2020

With 20 years of operations, multiphase flowmeters (MPFMs) using a combination of venturi and multi-energy gamma-ray absorption have gained acceptance in the oil and gas industry by demonstrating reliable measurement and operational robustness. Nonetheless, some challenging operating scenarios are encountered such as significant water salinity changes in multiphase and wet-gas flows and rapid detection of small water quantities during production.
Although MPFMs are not affected by small water salinity changes, inaccurate flow rates can be calculated when water salinity significantly departs from the initial properties. To maintain measurement metrology as per specifications, the water-point should be manually modified to track variations; however, this operation is time consuming and may incur nonproductive time. The salinity change measured by a newly developed sensor can be provided seamlessly to MPFMs to automatically update the water point calibration, thus ensuring good flow rate measurement performance over a wider water salinity range. Extensive validations at several flow loop facilities and field tests, including frac flowback operations, demonstrate the robustness of the method in terms of hardware reliability and the delivery of high-quality data when used with MPFMs with digital connectivity, which opens the way to unmanned production monitoring operations. Interpreting multiphase mixture's dielectric constant and electrical conductivity simultaneously measured by the new microwave water salinity sensor at a high data acquisition rate shows that water salinity can be tracked online in the presence of oil, gas, and sand, and small water quantities down to 50 ppm (part-per-million) water volume fraction (WVF), from the typical ~1000-ppm WVF for the MPFM, can be detected rapidly in multiphase and wet-gas flows.
This paper describes the working principles of the new sensor that enable additional capabilities to maintain accurate water-liquid ratio (WLR) measurement in situations where significant water salinity changes occur and to provide a rapid, much lower WVF detection level. Successful cases demonstrating an accurate real-time salinity monitoring in flow loop tests and in field operations are also presented.
Compositional Tracking: Predicting Wellstream Compositions in Tight Unconventionals
Authors: Carlsen Mathias Lia , Dahouk Mohamad Majzoub , Mydland Stian , Whitson Curtis Hays 
Published: January 2020

Wellstream compositions are needed for a range of critical engineering applications but it is impractical and too expensive to acquire these compositions frequently (e.g. daily) for every well in an unconventional basin. Detailed PVT studies that provide wellstream compositions can easily cost 25,000–50,000 USD and are typically performed on less than 1% of the wells in a "shale" basin. This paper provides methods to predict wellstream compositions daily in wells without detailed PVT analysis by using readily available production and well test (fluid sampling) data.
The three different methods presented all leverage a field-wide equation of state (EOS) model together with a varying degree of available production and well test data. The EOS model used should honor all the available fluid data in the relevant field, region, or formation, and should be developed based on as many detailed PVT studies as possible. The difference between the three different methods is the amount and type of data typically available, ranging from production data only to extensive compositional well test data.
This paper shows that accurate wellstream compositions can be predicted by using a field-wide EOS model together with production and well test data. The accuracy of the different methods depends on (1) the amount of available measured data, (2) the quality of the available measured data and (3) how well the EOS model captures the phase characteristics of the relevant fluid. The proposed methods provide a tool to consistently and accurately calculate daily wellstream compositions for all wells in a cost-efficient manner.
EOS models enable convenient and flexible calculations for describing phase behavior of petroleum fluids. However, to use an EOS model, three input parameters are needed: temperature, pressure and composition. In unconventionals, temperature and pressure are almost always available, but wellstream composition is not. The purpose of this work is to make wellstream compositions readily available for unconventional fields with thousands of wells, and thereby unlock the potential for EOS model utilization.
