The Role of Technology and Social Media in Spreading the Qur'an and Hadiths by Mubalig
Authors: Hidayaturrahman Mohammad , Putra D.I Ansusa
Published: January 2020

This research was conducted to find out how the role of technology and social media in spreading Al-Quran and hadith by the mubalig. This research uses qualitative descriptive approach, while the method of collecting data with observation on the activities of the mubalig and dai who perform religious daâ€™wa activities, both in mosques, langgar, and majlis taklim assemblies held at homes of pilgrims or mubalig house. This research found that, mubalig already flat using technology and social media for the purposes of their daâ€™wah. The preachers use technology and social media for various purposes of daâ€™wa, communicating with the congregation of recitation, to read references of religious material, as well as as a means to store the propagation material which subsequently submitted during the recitation. The last is to make existing apps their devices to recall verses or hadiths that happen to be forgotten when delivering lecture material. The mubalig rate, technology and social media are something positive to use as a medium of communication preaching. So that mubalig are not allergic to technology and social media, even some of them become active users in social media. Similarly, in his own devices there are many applications of the Qur'an and Hadith. Carrying a device is an effective way of learning, carrying the reference of the book, because it does not have to bring a large book of physical to come preach to various places and locations. Technology is considered to be able to connect them with the other ustaz, kiai or religious figures in the same or different organization.
Dialektika Hadis Nabi dengan Budaya Lokal Arab
Authors: Halim Abd.
Published: January 2020

Perkataan Nabi Muhammad tidak bisa dipisahkan dengan konteks situasi yang dihadapinya. Konteks tersebut bisa jadi situasi sosial, politik, ekonomi dan budaya. Terdapat beberapa hadis yang harus dipahami dengan mempertimbangkan konteks sosio-kultural lokal Arab. Paper ini akan membahas tentang dialektika hadis dengan budaya lokal Arab. Dengan menggunakan pendekatan kontekstual, bisa disimpulkan bahwa terdapat hadis-hadis yang berlaku universal di samping juga terdapat hadis-hadis yang hanya berlaku temporal dan tentatif. Hadis-hadis temporal dan tentatif ini direkomendasikan untuk ditafsirkan ulang daripada langsung diterima dan digunakan sebagai sebuah aturan yang final.

Authors: Burhanuddin Mamat S , Syamsuddin Muh. , Qudsy Saifuddin Zuhri
Published: January 2020

Sosok Nawawi al-Bantani sangat terkenal di Indonesia. Kajian terhadapnya membentang mulai dari gagasannya mengenai tasawuf, al-Quran, dll. Sejauh ini belum ada penelitian yang mencoba untuk mengklasifikasikan kajian terhadap Nawawi al-Bantani. Di sinilah letak signifikansi dari artikel ini. Dengan berangkat dari pertanyaan karya apa dan sejauh mana kajian para peneliti terhadap tokoh ini, dengan metode sejarah. Kami menemukan bahwa kajian al-Bantani cukup ekstensif pada periode setelah 2007-2017, namun karena karya al-Bantani yang dapat diakses sangat terbatas, maka kajiannya hanya fokus kepada beberapa kitabnya saja.
Qital: Reinterpretasi Pendekatan Humanis
Authors: Rahmawati Ana , Laila Azzah Nor
Published: January 2020

Penelitian ini bertujuan untuk mencari sisi humanis pada lafadz qital (perintah untuk perang) dalam Islam. Menggunakan metode deskriptif kualitatif dengan pendekatan kajian pustaka penulis menemukan sejumlah perintah qital dalam Islam. Dan berdasarkan hasil analisis disebutkan bahwa kata qital merupakan masdar dari kata qatala yang memiliki arti pertempuran atau peperangan. Terdapat dua istilah yang sering menimbulkan pahaman yang kurang tepat yaitu antara kata al-qital dengan al-qatl keduanya terlihat sama namun keduanya memiliki arti dan definisi yang jelas berbeda. Al-qital berarti peperangan atau pertempuran yang didefinisikan dengan adanya dua pihak yang keduanya saling menyerang serta mengupayakan pembunuhan untuk melawan upaya dari pihak lawan. Berbeda dengan makna al-qatl yang berarti pembunuhan yang didefinisikan sebagai upaya membunuh pihak lain. Perintah qital dalam Islam dapat dianalisa sebagai perintah berperang dalam upaya mempertahankan diri dari serangan musuh atau untuk menahan serta menghentikan serangan dari musuh, bukan berarti pembunuhan.Kata kunci: Â qital, peperangan, sejarah Islam, penafsiran, hadits

Authors: Nur Ariesta Eka , Simatupang Ervina
Published: January 2020

Illocutionary act is part of speech acts which are something in order to do something as what the speaker intents. Based on Yule (1996: 48) stated that illusionary act is performed via the communicative force of utterance. Illocutionary act is a performance of act in saying something .Next, based on Vanderveken, Daniel (2009: 97) mentioned illocutionary acts of the meanings in the use and comprehension of language. The finding shows that the dialogue in the Death Cure movie contains each of illocutionary acts. They are representative illocutions, directives, illocutions, committees, expressives, and declarations. 2 types of strategies namely direct strategy, which has a literal meaning in the context and indirect strategy which has implicates in the context of speech, are used by speakers in uttering their speech. The data is taken from The Death Cure Movie. The method used in this thesis is the analytical descriptive- comparative method. It is used to get a clear and objective description of the Illocutionary in the movie.
Keskustelijoiden yksilölliset erot suomenkielisen verkkokeskustelun romanikielisten sanojen käytössä
Authors: Salo Mirkka
Published: January 2020

Tarkastelen tässä tutkimuksessa kymmenen nimimerkin kielenkäyttöä suomenkielisellä internetin keskustelupalstalla suomi24.fi-romano. Metodina on yksilömurteita vertaileva variaationtutkimus. Olen kerännyt tutkimukseen kymmenen nimimerkin kaikki viestit ajalta 22.2.2003–18.7.2013. suomi24.firomano on tämän tutkimuksen valmistumisen aikana ainoa erityisesti Suomen romaneille tarkoitettu keskustelupalsta internetissä. Keskustelupalsta on suunnattu romanien väliseen keskusteluun. Keskustelufoorumin pääkieli on suomi, mutta monet keskustelijat käyttävät suomen varieteettia, joka sisältää romanikielisiä tai romanikieleen pohjautuvia sanoja, romanikielisiä rakenteita tai lauseita. Tutkin tällaisia viestejä. Tarkasteltavana ovat kunkin nimimerkin käyttämät romanikieliset elementit (lekseemit ja rakenteet), niiden määrä, sanaluokat, morfologia ja taivutus sekä käyttötehtävät.Osa nimimerkeistä käyttää vain substantiiveja, osa laajemmin eri sanaluokkiin kuuluvia lekseemejä. Yhteinen piirre kirjoittajilla on romanikielisen elementin käyttö romani-identiteetin tai Suomen romanikulttuuriin liittyvän asian ilmaisemisessa. Kirjoittajien väliset erot romanikielen taivutuksessa ja kirjoitusasuissa voivat johtua taivutetun romanikielen käytön harvinaistumisesta. Nimimerkit eivät korjaa toistensa romanikielentaivutusrakenteita tai kirjoitusasuja. Kirjoittajien yksilömurteet eroavat eniten romanikielisen sanaston määrässä, mutta eroa on myös kieliopillisten rakenteiden määrässä ja monipuolisuudessa.
Kielenvaihto monikielisissä kokouksissa - osallistujien kielitaito ja vuorovaikutuksen sujuva eteneminen
Authors: Kotilainen Lari , Lehtimaja Inkeri
Published: January 2020

Yhä useammilla suomalaisilla työpaikoilla puhutaan kotimaisten kielten lisäksi myös muita kieliä, esimerkiksi englantia tai maahanmuuttajakieliä. Uusi kielitilanne johtaa vuorovaikutuksen haasteisiin, sillä kaikki työntekijät eivät välttämättä osaa hyvin kaikkia työkieliä. Tässä artikkelissa esittelemme tapoja, joilla työntekijät hyödyntävät työympäristön monikielisyyttä varmistaakseen mahdollisimman tehokkaasti etenevän vuorovaikutuksen. Tarkemman kiinnostuksen kohteena ovat kohdat, joissa vaihdetaan puhuttavaa kieltä. Aineistonamme on videoituja työkokouksia suomalaisesta kulttuurialan järjestöstä. Kokousten yleisimmät kielet ovat suomi ja venäjä. Metodinamme on etnometodologinen keskusteluntutkimus, eli tarkastelemme kielenvaihtoja vuorovaikutuksen mikrotason käytänteinä. Lähestymme monikielisen työvuorovaikutuksen käytänteitä sellaisten kielenvaihtojen kautta, jotka liittyvät vuorovaikutuksen etenemisen ongelmakohtiin. Tarkastelemme ensinnäkin sitä, missä tilanteissa ja miten osallistujat vaihtavat itselleen vahvempaan kieleen, ja toisaalta sitä, mitkä tekijät saavat heidät vaihtamaan vastaanottajalle vahvempaan kieleen. Tarkastelemamme kielenvaihdot liittyvät ongelmiin joko puheen tuottamisessa, ymmärtämisessä tai aktiivisessa vastaanottajuuden osoittamisessa. Vaihtamalla kieltä joustavasti tilanteen vaatimusten mukaan – ja toisinaan vastoin eksplisiittisiä sopimuksia käytettävästä kielestä – osallistujat varmistavat, että kokousvuorovaikutus etenee ja kaikilla kokouksen osanottajilla on mahdollisuus osallistua vuorovaikutukseen mahdollisimman täysipainoisesti.
Relevance of The National Research Agenda to the Research Initiative of a Higher Education Institution in the Philippines
Authors: Ramoso Maura Gina D , Ortega-Dela Cruz Ruth A
Published: January 2020

This study used survey research design to determine the relevance of the National Higher Education Research Agenda (NHERA) to the research initiatives of a specific Higher Education Institution (HEI) in the Philippines. It employed universal sampling of faculty and administrative staff as well as students to analyse discrepancy in the perceptions regarding the degree of applicability, importance and urgency of the NHERA to the HEI’s research initiatives. Result of Mann-Whitney U Test revealed no significant difference between the ratings of the employees and students regarding the degree of relevance. This indicates that the respondents were all in agreement with the set of research agenda themes that should be prioritised by the institution. These themes include those related to the program curricular studies; institutional development studies; manpower demand/supply studies; policy-oriented studies on accreditation and quality assurance mechanisms, among others. These are the NHERA themes that need to be given much emphasis in the research agenda and initiatives of the institution as these are all for the sake of achieving their institutional learning outcomes towards developing skilled and competent manpower in the country’s aviation industry.
Ranking Japan’s Institutions of Higher Education, 2017: A Comparative Analysis
Authors: Cramer Kenneth M , Yoo Hyein , Manning Dana
Published: January 2020

The present study examined the 2017 Times Higher Education annual rankings for Japanese institutions of higher learning. Based on the analytic model as mapped out previously using Canadian data, we offered a similar protocol for the top 100 institutions of higher education in Japan. Three analyses showed that: (a) overall rank correlated with individual index ranks for 9 of the 13 indices, (b) the schools appearing among the top institutions overall ranked significantly better on 8 of the 13 indices compared to schools appearing among the bottom institutions overall, and (c) schools were empirically grouped into four meaningful families or clusters whose constituent members shared a comparable profile of indices. We offer a juxtaposition of the present results to annual evaluations from Canada’s institutions of higher learning. The wider implications include an international comparison of institutions of higher learning, a proposed analysis protocol that Japanese education administrations may further pursue, and a categorical breakdown of educational institutions in Japan. Directions for future research are outlined.

Authors: İlhan-Beyaztas Dilek
Published: January 2020

The aim of this study is to determine the relationship between the way that teacher candidates perceive the teaching approaches used by the instructors at the faculty of education and the learning approaches they prefer. The study group of this research was composed of 525 students from different departments of the faculty of education to determine the relationship between the teaching approaches and the learning approaches. As a result of the research, it was determined that the means of Information Transfer-Teacher - Focused (IT-TF) approach were higher than Conceptual Change-Student-Focused (CC-SF) scores across university departments and grade levels. It was also determined that the means of the deep and strategic learning approach across university departments, genders and grade levels were higher than the mean scores of the surface learning approach. In addition, there was a strong, positive and significant relationship between the mean score of IT-TF and the mean score of CC-SF, whereas it was found that there was a small, positive and significant relationship between the mean scores of IT-TF and CC-SF and DLA and SLA.
Student Assessment of Teachers (SAT): Towards a Basket of Approaches
Authors: Ubong Bassey , Okpor Mercy O.
Published: January 2020

In some institutions of higher learning, one of the approaches to successful governance is through student assessment of teachers, dubbed Student Assessment of Faculty or Student Evaluation of Teaching and extensively used in the United States of America (USA). In schools and colleges, the usual largest bloc and primary stakeholders are the students. Students should therefore assess teachers for the purpose of improving the system for all stakeholders including themselves. Teaching is a service in a marketing framework and where it is offered, the buyer is in the best position to assess the offering for better performance. This paper advocates for student assessment of their teachers at the end of each teaching cycle and suggests a basket of approaches to reduce the dissonance that accompanies the exercise where applied. A template is suggested in the paper.
A Genre-Based Investigation of the Introduction Sections of Academic Oral Presentations
Authors: Makhtiar Singh Kuldip Kaur , Mohamad Ali Afida , Chan Mei Yuit , Tan Helen
Published: January 2020

The academic oral presentation (henceforth AOP) is an important genre for tertiary students across various courses and disciplines in the university. Despite the importance of AOPs for undergraduate students, relatively little is known about this genre. Using Swales’ (1990, 2004) notion of move analysis,  this paper compares the rhetorical structure of the introduction sections of academic oral presentations from two different fields, namely English language and Administrative Sciences. The findings show some similarities in the AOPs whereby the introduction section contained three moves, and their related steps were similar to previous studies on the rhetorical structure of oral presentations but with few variations.  The linguistic features used were also found to be similar in both corpora revealing that students were able to transfer their rhetorical knowledge and linguistic features from one context to another. This study reveals that variation in AOPs is possible in different courses and disciplines. Thus, having genre awareness can help students adapt their genre knowledge to the context.
Factors Affecting Bangladeshi Private University Students’ Choice of Institutions for Undergraduate Study
Authors: Anam Rumana Liza
Published: January 2020

In a highly populated country like Bangladesh where standards of living are rising steadily, more and more students are pursuing studies at university level.  With only a few publicly funded universities, private universities are now the main avenue for pursuing undergraduate studies. Competition is growing among these universities operating in a heavily regulated sector.  Substantial amounts are often being spent on attracting potential students.  However, without proper research into the area and understanding how students choose their universities, resources may end up being used ineffectively. This conceptual paper aims to identify the factors that students consider when choosing their universities.

Published: January 2020

The classification and detection of defects play an important role in different disciplines. Research is oriented towards the development of approaches for the early detection and classification of defects in electrical drive systems. This paper, proposes a new approach for the classification of induction motor defects based on image processing and pattern recognition. The proposed defect classification approach was carried out in four distinct stages. In the first step, the stator currents were represented in the 3D space and projected onto the 2D space. In the second step, the projections obtained were transformed into images. In the third step, extraction of features whereas the Histogram of Oriented Gradient (HOG) is used to construct a descriptor based on several sizes of cells. In the fourth step, a method of classifying the induction motor defects based on the Support Vector Machine (SVM) was applied. The evaluation results of the developed approach show the efficiency and the precision of classification of the proposed approach.
An Eight-Node Hexahedral Finite Element with Rotational DOFs for Elastoplastic Applications
Authors: Ayadi Ayoub , Meftah Kamel , Sedira Lakhdar , Djahara Hossam
Published: January 2020

In this paper, the earlier formulation of the eight-node hexahedral SFR8 element is extended in order to analyze material nonlinearities. This element stems from the so-called Space Fiber Rotation (SFR) concept which considers virtual rotations of a nodal fiber within the element that enhances the displacement vector approximation. The resulting mathematical model of the proposed SFR8 element and the classical associative plasticity model are implemented into a Fortran calculation code to account for small strain elastoplastic problems. The performance of this element is assessed by means of a set of nonlinear benchmark problems in which the development of the plastic zone has been investigated. The accuracy of the obtained results is principally evaluated with some reference solutions.
Study of Powder Particle Size Effect on Microstructural and Geometrical Features of Laser Claddings Using Response Surface Methodology RSM
Authors: Boussaha El Hadi , Aouici Samia , Aouici Hamdi , Bahloul Abida
Published: January 2020

A continuous CO2 laser (10.6 µm wavelength) was adopted to investigate the influence of powder particle sizes on microstructural and morphological characteristics of laser claddings.

To study the potential of powder in controlling the incident laser energy, different average particle sizes of Ni-base powder were deposited on an austenitic stainless steel X3CrNi18-10 substrate. The energy value necessary to melt a mass m of powder was calculated. The results indicate that this energy decreases with particle sizes.

The claddings obtained with small particle sizes revealed a good morphological aspect and a low dilution of the cladding layer in the substrate, yet enough to create a very good metallurgical bond. The residual stress state was also influenced. Concerning modeling, we have elaborated residual stress model in the case of laser cladding by exploiting the response surface methodology (RSM), using a quadratic regression model. Combined effects of three laser cladding parameters on the residual stress is explored by a statistical analysis of variance (ANOVA). Results show that the residual stress is influenced principally by the power delivered by laser beam and by the scanning speed. It is also indicated that the size of powder particle is the dominant factor affecting the residual stress.
”You Must Swear [...] That Care for the Well-Being and Health of Women in Labor and Their Infants Shall Be the Only Objective of Your Work.” Midwives in the Galician Autonomy — Statistical and Geographical Analysis by Counties
Authors: Rejman Sabina
Published: January 2020

The study analyses the number of midwives in the counties of Eastern and Western Galicia in census years 1869, 1880, 1890, 1900 and 1910, and the ratios per cadastral commune, 10,000 square kilometers, 10,000 civilians and 10,000 women in a county. The analysis was based on Austrian and Galician statistical reports. The results of the study confirmed that Eastern Galicia outnumbered Western Galicia in terms of midwives. However, it was in Western Galicia where the rate of growth was higher, and the effects of the 1910 collapse more moderate. This could have been due to an amendment to the 1897 midwifery regulations. The position of individual counties changed, depending on the year and the specific measure. In Eastern Galicia, Lisko county ranked the worst and Horodenka, Śniatyń, Tarnopol, Trembowla, and Brzozów counties ranked the best. In Western Galicia, Limanowa county ranked the worst, while Brzesko, Kraków, Łańcut, Wadowice, Przeworsk, and Podgórze counties ranked the best. There is a strong positive correlation between the rank and natural conditions (water, soil, climate), type of crops, agricultural development and processing, transport system (road and rail), population, and stimulating function of large urban centers. Favorable conditions were correlated with higher values in measures of the number of midwives.
Globalisation and Women’s Work in the Beedi Industry
Authors: Pande Rekha
Published: January 2020

The present paper views globalisation and women’s work and exploitation in a micro enterprise in India, the beedi (indigenous cigarette) industry with a case study from one of the states in India. Rural occupational structures and employment patterns in India have undergone a transition in the last few decades due to globalisation. Newer forms of employment like construction work, domestic services and beedi making have become alternatives to agricultural labour for women. Beedi is an indigenous cigarette, in which tobacco is rolled in a tendu leaf and tied with a cotton thread. This is smaller and less expensive than a cigarette and in the popular imagination it stands for the working class. This work is done sitting at home and mostly women and girls do it. This is a very gendered industry, for only women and girls that too from low-income groups make beedis. There is a lot of exploitation in this industry and this has only increased with the advent of globalisation but this is generally ignored by data gathering systems, policy makers and administrators. There is an occupational health hazard too for many of these workers suffer from various health hazards not because they are smoking these beedis but because they are making them.
Influence of Family Benefits on Women’s Professional Activity. The cases of Poland, the United Kingdom, and France
Authors: Kacperska Magdalena
Published: January 2020

Women show greater and greater activity on the job market, they obtain better positions, salaries, etc. However, the statistics concerning their professional activity differ from those of men. We should take into consideration the fact that women are the ones who give birth to children and, in majority, take care of their upbringing, especially in the first years of child’s life. Policies of particular states are different in terms of the amount and availability of family benefits, and that can be reflected in women’s willingness to return to work.

Published: January 2020

In many Countries legislation forces Oil&Gas Companies to implement a Process Safety Management System (PSMS) to prevent and mitigate major accidents associated to the release of energy or hazardous substances. In plants where activities may have lower process risks, such as contaminated groundwater treatment plants, the implementation of a PSMS usually is not mandatory. This paper outlines how also these plants could benefit from a Process SafetySafety framework.

A PSMS can be developed in line with the framework of an internationally recognized organization (CPPS, Energy Institute, IOGP, OSHA) to be applied to activities with significant HSE risks while it may be considered as an internal standard for low-risk activities. The effectiveness of the PSMS adopted and its correct and complete implementation in accordance with the selected framework may be evaluated by a dedicated audit protocol. The typical findings from audits carried out on reference upstream and downstream installations as well as on some low-risk plants were collected and performance compared in order to identify peculiarities in terms of good practices and recurrent areas for improvement.

The main results of the benchmark are presented in this paper. The results confirm that the effectiveness of a PSMS is strictly linked with the level of risks in the activities and how such risks are managed both in administrative and operating processes. A robust risk-based approach in all processes, fostered by a visible commitments of top management, is the successful key for enhancing the Process Safety culture of personnel and ensuring safe performances and business continuity in operations, irrespective of the risk level in activities.

The paper also provides a roadmap for implementing a PSMS in contaminated groundwater treatment plants, tailoring the Process Safety framework to the specific operative needs and risks.
Application of Different Fluid Injection Methods to Reduce Breakdown Pressure

Published: January 2020

Using hydraulic fracturing laboratory experiments, we previously showed that different fluid injection methods for pressurizing a borehole lead to significant variations in specimen breakdown pressure. In this paper, we present a numerical analysis of these experiments to investigate the mechanism behind such variations.

A multiphase, poro-elastic numerical simulator is developed and utilized in this work. The equations for multiphase, multi-component fluid flow in a deforming porous medium are described and the solution algorithm used in the numerical simulator is explained. The simulator is verified against a Buckley-Leverett solution for multiphase flow and against Mandel's compaction problem for poro-elasticity. We constructed a two-dimensional (2D) numerical model with the same dimensions and properties of the laboratory specimen. The specimen is a square sheet with a circular borehole in the middle, and anisotropic far-field stresses are applied to the specimen. A total of five fluid injection cases were simulated. In the first four cases, glycerin was injected into initially dry specimens (air-saturated at atmospheric pressure) using a) fast injection rate, b) slow injection rate, c) cyclic pressure ramp, and d) constant pressure injection. Glycerin was injected in the fifth case into an initially glycerin-saturated specimen using the same fast injection rate in the first case.

As the fluid is injected into the specimen, we demonstrate the advancement of fluid saturation front and the development of pore pressure and effective hoop stress around the borehole for the five fluid injection cases. At the end of injection, it is clearly shown that the extent of glycerin infiltration or leakoff into the specimen is smallest for the fast injection, and becomes respectively larger for the slow injection, cyclic pressure ramp, and constant pressure injection. The higher fluid leakoff among the different cases also corresponds to higher pore pressure distributions and induced tensile stresses around the borehole that reduce the required breakdown pressure. The induced hoop stresses are most tensile for the constant pressure injection and least tensile for the fast fluid injection. We show that the least tensile stress using the fast fluid injection becomes the most tensile among all five cases when the specimen is fully saturated with glycerin initially.

This study draws a novel linkage between four different topics that are investigated separately in the literature: 1) the effect of fluid injection rate on breakdown pressure, 2) the effect of cyclic borehole pressurization on breakdown pressure, 3) the effect of constant pressure injection on breakdown pressure (static fatigue behavior), and 4) the effect of rock saturation on breakdown pressure. In terms of field applications, the fundamental findings from this study are utilized to develop new methods for pre-frac injection tests to reduce breakdown pressure in highly-stressed formations.

Tracer technology is a very efficient diagnostic tool in the oil and gas industry to obtain valuable information about reservoirs. The interpretation of tracers that have traversed the reservoir reveals characteristics such as inter-well connections, heterogeneities, and water movements that can be used to improve hydrocarbon recovery efforts. A strong need exists for tracers that can withstand increasingly harsh reservoir conditions such as high pressure, high temperature, high salinity and sour environments. Recent progress in nanotechnology and developments in nanoparticle synthesis and engineering bring possibilities for tracer applications. This paper discusses a unique approach towards unconventional properties shown by nanoparticle tracers.
NMR Investigation of Viscoelastic Surfactants Compatibility with Corrosion Inhibitors

Published: January 2020

Viscoelastic surfactants (VES) have been successfully applied as acid-diversion fluids. However, high temperature, interaction of VES and metallic cations, alcohol-based additives, and chelating agents all interfere with the apparent viscosity of the VES-based acid and reduce its efficiency. One of the most essential additives in acidizing that can significantly interfere with VES behavior is corrosion inhibitors. Many parameters would impact the performance of corrosion inhibitors including tabular materials, acid types and concentrations, as well as the presence of other additives that might interfere with the corrosion inhibitors. Hence a wide range of corrosion inhibitors is available to address corrosion issues adequately. The present study characterizes the interactions of various types of industrial corrosion inhibitors with different kinds of VES-based systems including zwitterionic and nonionic surfactants.

Viscosity measurements were conducted on the VES-based solutions combined with different concentrations of tested corrosion inhibitor formulae, the industrial packages, to characterize the rheological properties of the VES-based acids. To understand the nature of the VES interactions with corrosion inhibitors, nuclear magnetic resonance (NMR) spectroscopy was conducted.

The results of rheological measurements showed that addition of different types of corrosion inhibitors in the industrial concentration range leads to change in the conformation of micellar structures and rheology of the VES-based solutions. NMR was conducted to determine the chemical groups involved in the interaction/reaction of corrosion inhibitors and viscoelastic surfactants. Furthermore, the effects of additives and solvents present in industrial corrosion inhibitors were studied. The results showed that amide part of VES is the leading functional group that can interact with corrosion inhibitor solutions and causes alternation of micellar structures due to change in the repulsion forces between surfactants headgroups.

The results presented in this study can be used to select corrosion inhibitors more efficiently and optimizing their effectiveness in the presence of VES-based fluids. These results can be utilized to predict any probable interactions and rheological changes in VES-based stimulation fluids due to the addition of corrosion inhibitors.

D1 is an oil and gas field located offshore of Bintulu, Sarawak. It's a hub with several tie-in fields namely, D1-A, D1-B, D1-C, D2, D3, E1 and J1. Over the years, as more fields were tied-in to this hub, there have been significant increase in both oil and gas production. D1's facilities were designed to cater for high liquid flowrate. Hence, there was no need for a major topside modification to cater for increase in liquid production. However, with increasing associated gas (AG) produced from all these tie-in fields, a serious topside constraint arose concerning associated gas due to insufficient compressor ullage. Consequently, the excess gas which cannot be compressed had to be flared resulting in higher flaring/venting (FV) than the limit set by the host government authority. In order to avoid any FV violation, the field's operator had to increase the operating pressure of the low and high pressure (LP and HP) separators to reduce the amount of gas that was being flared. This paper describes the topside optimization that was diligently conducted over a period of 7 months to test and achieve an optimum production while maintaining FV within limits. Implementation of this effort involved process study to evaluate the compressor ullage availability verus current and future gas production from the hub. Based on this info, the operating philosophy of the existing 2 compressor trains at D1 were changed from 2 x100% to 2 x 50% in which both trains were put online concurrently instead of 1 unit running and 1 unit on standby. This new operating philosophy required changes to the compression system and re-strategizing the maintenance and spare parts management for both units to ensure sustainable operation over the long run. This zero-cost optimization revolves around 3 key performance indicators. Firstly, the excess gas that was previously flared can now be compressed and exported contributing to more than 100% increase in gas sales. Secondly, in line with the hub's efforts to reduce its carbon footprint, flare reduction of almost 50% was achieved. Finally, from subsurface perspective, running 2 compressor trains reduces the operating pressure of LP and HP separators by 1.5 barg and 2.5 barg respectively resulting in a significant reduction in backpressure to the wells. This improved oil recovery from wells across all the fields tied-in to D1 hub.
