Cultural difference determines the strategies used for entrepreneurship development. Pesantren (Islamic boarding school) as the oldest educational institution in Indonesia has a unique culture. Pesantren-based entrepreneurship development must be equipped with different characteristics of strategy. The purpose of this research is to explore the entrepreneurship development strategy based on the culture of pesantren through teleology approach. The subject of the current research is Pondok Pesantren Sidogiri (PPS) Pasuruan. It employs case study analysis. Interview and observation methods are used to collect the data. The teleology approach is used to understand entrepreneurial strategies under some perspectives which include; the involved subjects, the projected achievements, and the entrepreneurship development strategy based on the culture of pesantren. The results demonstrate the important role of kiai (pesantren leader), santri (students), and alumni in the development of entrepreneurship in Pondok Pesantren Sidogiri. They seek independence for the intention of worship. They practice the value of tabligh (transparent) and fathanah (professional) for institutional management called Koperasi Syariah (sharia cooperative). In addition, the administrative managers hold the values of shidiq (honest) and amanah (trustworthy). In conclusion, the strategy of pesantren-based entrepreneurship development has typical characteristics of pesantren.

Interactions in MOOCs: The Hidden Part of the Iceberg
Authors: Cisel Matthieu Tenzing
Published: November 2018

Interactions that take place between MOOC users outside of discussion forums, and out of the reach of course designers, have received little attention from the scientific community despite their potential influence on learner retention. Based on an online survey, we found that MOOCs are often used as an activity among friends and family, and not exclusively in the academics or in the workplace. Interactions between course users may continue beyond of the boundaries of the course, and sometimes into other MOOCs. These various interactions include collaborative tasks, as well as tasks which should be performed individually, such as assessments. This work illustrates the mismatch that can appear between prescribed and actual tasks, and the potential importance of interactions between users, to address the isolation that contributes to low retention rates for online learners.
Hacking History: Redressing Gender Inequities on Wikipedia Through an Editathon
Authors: Hood Nina , Littlejohn Allison
Published: November 2018

Editathons are a relatively new type of learning event, which enable participants to create or edit Wikipedia content on a particular topic. This paper explores the experiences of nine participants of an editathon at the University of Edinburgh on the topic of the Edinburgh Seven, who were the first women to attend medical school in 19th century United Kingdom. This study draws on the critical approach to learning technology to position and explore an editathon as a learning opportunity to increase participants’ critical awareness of how the Internet, open resources, and Wikipedia are shaping how we engage with information and construct knowledge. Within this, there is a particular focus on recognising persisting gender inequities and biases online. The qualitative interviews captured rich narrative learning stories, which traced the journey participants took during the editathon. Participants transformed from being online information consumers to active contributors (editors), prompting new critical understandings and an evolving sense of agency. The participants’ learning was focused in three primary areas: (1) a rewriting of history that redresses gender inequities and the championing of the female voice on Wikipedia (both as editors and subject matter); (2) the role of Wikipedia in shaping society’s access to and engagement with information, particularly information on traditionally marginalised subjects, and the interplay of the individual and the collective in developing and owning that knowledge; and (3) the positioning of traditional media in the digital age.
The Inherent Tensions of “Instant Education”: A Critical Review of Mobile Instant Messaging
Authors: Pimmer Christoph , Rambe Patient
Published: November 2018

This paper critically reviews literature on the role of Mobile Instant Messaging (MIM) applications, such as WhatsApp, in supporting learning and teaching practice. Using formal qualitative synthesis as its methodology, and dialectical theory as an analytical framework, our main objective was to identify tensions, affordances, constraints, and resolution strategies in educational uses of MIM. In contrast to prior work, the analysis offers a nuanced and complex picture of the use of MIM in learning and teaching settings. Instead of facilitating the creation of educational outcomes in a straightforward manner, the realities of MIM use are socially constructed and the subject of conflictual negotiations. The educational use of MIM requires users to navigate the interdependent dialectical tensions of immediacy versus delays (temporal dimension), intimacy versus detachment (relationship dimension) and task versus ludic orientation (intellectual dimension). The findings also reveal a number of behavioural and technical resolution strategies that users deploy to manage these tensions.

SOCIAL STRUCTURE OF TAMBOV EPARCHY MONASTERIES IN THE LATE 18th – 19th CENTURIES
Authors: VOLKOV Maksim Sergeevich
Published: November 2018

The relevance is determined by the growing interest to the problem of the functioning of Orthodox monasteries of Tambov Eparchy in the Synodal period. In this regard one of the main tasks is to try to understand the particular aspects of the internal structure of monastic life. Such a goal can be achieved only as a result of detailed consideration and analysis of the social and quantitative composition of the monastery population. Monks were the main guardians of the way of life, culture, and history of their monasteries. The principles of the relationship of different social groups within a single community, the level of their literacy and age often determine the direction of development and the main types of both internal and external activities of monasteries. The main documents are considered in the research, the main of which are “Vedomosti about the Abbot and Monastics” for various years. In such reports, various information was provided about monastics, novices and monastic workers. They managed to extract detailed statistical and demographic information, as well as analyze the social composition of the main Orthodox monasteries of the eparchy at certain periods. It was also possible to establish the average age of entering the monastery, the period of testing, the main occupation of the population, which largely depended on their social status in the world and on the level of education.

The relevance is determined by the dynamic nature of modern social processes, the neсessity to develop new methods of mobility, transfers, permanent changes of stable aspects of social reality studying. We analyze the extent to which the existing methodological and logical apparatus of authoritative social theories is suitable for the study of cultural memory in modern conditions. To solve this problem we analyze some methodological approaches and theories: the views of J. Urry, J. Olick, A. Assmann, F. Hartog, H. Lubbe, as well as actor-network theory, activity approach. The interdisciplinary nature of cultural memory studies has been substantiated, the consequence of which is the necessity for the synthesis of modern approaches of various humanities and social sciences capable of building a dynamic picture of the past. The relevance of the problem of matching the existing terminological vocabulary of modern humanities and social sciences to the needs of describing and understanding the dynamic picture of the world. It is proved that the most relevant tasks of the dynamic nature of cultural memory study are actor-network and activity approaches, as they allow to take into account the impact on the content of images of the past made by not only people, but also various material and non-material actors, as well as to test the explanatory model of the functioning of the culture memory in the conditions of various challenges (for example, the intensification of migration flows).

STRUCTURAL AND FUNCTIONAL MODEL OF SOCIAL AND PEDAGOGICAL SUPPORT OF FAMILIES RAISING CHILDREN WITH HIV-POSITIVE STATUS
Authors: LEVCHUK Svetlana Vasilevna
Published: November 2018

We consider the theoretical foundations of structural and functional model aimed at providing social and pedagogical support to families raising children with HIV-positive status. Modern statistical materials confirming the relevance of the problem are analyzed, in connection with which it is obvious that the number of infected people and, as a consequence, their problems of various nature: medical, legal, psychological, social, pedagogical. It is concluded that the diagnosis of HIV infection has a greater impact on the change in social status and has gender differences. An important aspect of the proposed work is the statement of the fact that the support of families raising an HIV-infected child remains one of the important problems of modern Russia. Analyzing the causes of the existing problems of the named category of families, we consider as the primary the low level of knowledge about the disease, methods of infection and protection measures, which, as a result, reduces the level of their social activity. The main content is focused on the description of the structural and functional model of social and pedagogical support for families raising a child with HIV-positive status and involving such components as target, conceptual, content-technological and effective. We present a detailed review of each component. The basic approaches to solving the problem are analyzed, among which the personal-social-activity approach is defined as the main one, which is connected with the need to integrate the educational effects of the environment on the individual in the process of activity. A crucial part is to identify the key principles on the basis of which social and pedagogical support for families raising an HIV-infected child is based. We considers such principles as consistency, complexity, variability and flexibility of social and pedagogical interaction, individual orientation. Their detailed content is presented. Determining the content of direct activities with the family, we insist on the use of various support strategies, which provides a basis for the rational use of the entire depth of social resources. Paying special attention to the level of subjectivity of the family, we determine its criteria and divides them into three groups. Such classification is necessary not only for scientific purposes, but has a high practical significance for specialists, volunteers and representatives of public organizations that provide social and pedagogical support for these categories of families. The support strategies are aimed at organizing evidence-based, competent social and pedagogical support for families raising children with HIV-positive status, ensuring their active participation in social life, the implementation of their social and personal needs, protection of rights and interests.

Authors: BOUSSAHA Amir , GILLARD Marina Vladimirovna
Published: November 2018

In the development of modern society, the growing interest in conflict and conflictology is known, which has several grounds for it. An important feature of modernity is the increase in the number of conflicts that arise in various spheres of social interaction. The main signs of the emergence and manifestation of the conflict is the lack of mutual understanding between people, various forms of violence, aggression, terrorist acts, the presence of people in uncertainty in the future, fear of the future, the very problem of conflict in real life becomes more complicated, which leads to the relevance and importance of studying this phenomenon. We present a retrospective analysis of many researches, which examine the stages of development and formation of conflictology as an independent science, and sports conflictology as one of the emerging sectors of conflictology as a whole. It should be noted that the results of the theoretical study provide an opportunity to identify the prerequisites for the formation of the sports conflictology, which in turn allows approaching the study and the resolution of the conflict in sports overall and multi-disciplinary. Since conflictology is considered as interdisciplinary science, where large numbers of scientific disciplines studies the issue of conflict, as it is a universal phenomenon.

The current state of health of the conscription youth causes reasonable concern of specialists. It is especially important that the conscription service places high physical, psychological and social demands on military personnel, which can lead to disruption of the adaptation process, exacerbation of chronic diseases and socio-psychological discomfort. We substantiate the necessity of taking into account the indicators of morphological status of conscripts in the process of their physical training, as the physique, somatic type of person, significantly affect its predisposition to the types of motor activity, the energy supply of which is carried out according to different mechanisms. Given the relevance of this issue to improve the efficiency of physical training process, the goal of this stage of the research was development and validation methodology of physical training of conscripts on the basis of somatic type when defining the structure, content and regulation of the load of the physical exercise. The development of the methodology was based on the understanding of its experts as a set of tools, methods, techniques and ways of expedient execution of any work containing the exact order of the sequence of actions leading to the successful solution of the task. Its structure consists of a projective, substantive, procedural and control module, the elements of which together make it possible to carry out effective physical training of military conscription of different body types.

Published: November 2018

Cell-based therapies and tissue engineering applications require biocompatible substrates that support and regulate the growth, survival, and differentiation of specific cell types. Extensive research efforts in regenerative medicine are devoted to the development of tunable biomaterials which support various cell types including stem cells. In this research, the non-cytotoxic biopolymer polycaprolactone (PCL) was fabricated into 2D and 3D scaffolds with or without the low-pressure oxygen plasma treatment to enhance hydrophilicity. Cellular responses and biocompatibility were evaluated using a human Wharton’s jelly mesenchymal stem cell line (BCP-K1). The 2D PCL scaffolds enhanced initial cell attachment compared to the 3Ds indicated by a higher expression of focal adhesion kinase (FAK). Whilst, the 3D scaffolds promoted cell proliferation and migration as evidenced by higher cyclin A expression and filopodial protrusion, respectively. The 3D scaffolds potentially protected the cell entering to apoptosis/necrosis program and induced cell differentiation, evaluated by gene expression. Both 2D and 3D PCL appeared to have stronger effects on cell behavior than a control substrate (polystyrene). In summarize, the different configuration and surface properties of PCL scaffolds provide various options for modulation of stem cell behaviors, including attachment, proliferation, survival, and differentiation, when combined with specific growth factors and culture conditions.

Published: November 2018

The digital society is an outcome of the Internet which has nearly made everything connected and accessible no matter where or when. Nevertheless, despite the fact that conventional IP networks are complicated and very hard to manage, they are still widely adopted. The already established policies make the network configuration/reconfiguration a complex process that reacts to errors, load, and modifications. The prevailing networks are vertically integrated which makes things more and more complicated: Data planes and control are strapped together. Software-defined networking is a model that is meant to solve this issue by splitting the vertical integration and detaching the network’s control logic from the implicit routers and switches; this could be achieved by reinforcing centralization of network control and making the network programmable. In this work, we worked to implement MPLS networks with SDN, to enhance the traffic engineering over the network, and to minimize the network delay and latency, with minimum cost using three of the different SDN networks. The experiment results showed the advantage of the proposed approach for reducing the network delay, comparing with previous studies. Where the average of network delay in our approach reaches to 3.01 milliseconds.

Authors: Jeong Hieyong , Kido Michiko , Ohno Yuko
Published: November 2018

1) Background: Although many studies have supported the efficacy of multi-sensory environment (MSE) in reducing behavioral and psychological symptoms, and improving quality of life for patients with disabilities and caregivers, these studies didn't offer how to identify a high-risk candidate who would harm from MSE. Thus, this study was to propose a method to classify the high-risk group of cardiac arrest during MSE interventions through the relation between QT and RR intervals (QT-RR interval). 2) Methods: Eight disabled patients were participated in experiments to experience the virtual aquarium for 15 min with a projector and music. The QT-RR relation was measured by electrocardiography, then the risk was evaluated by computing the shortest distance from the mean of QT-RR relation to the standard curve. 3) Results: It was found that the risk of original cardiac arrest for the five patients was averagely 4.7 times higher than that for the three patients. It was considered that the five patients with higher risk came from the 0.6 times slower QT interval. 4) Conclusion: It was concluded that the proposed method to classify the high-risk group through QT-RR relation was good for the prevention of cardiac arrest through the unintended sudden strong stimulation.
Recognition of Urban Sound Events using Deep Context-Aware Feature Extractors and Handcrafted Features
Authors: Giannakopoulos Theodoros , Perantonis Stavros
Published: November 2018

This paper proposes a method for recognizing audio events in urban environments that combines handcrafted audio features with a deep learning architectural scheme (Convolutional Neural Networks, CNNs), which has been trained to distinguish between different audio context classes. The core idea is to use the CNNs as a method to extract context-aware deep audio features that can offer supplementary feature representations to any soundscape analysis classification task. Towards this end, the CNN is trained on a database of audio samples which are annotated in terms of their respective "scene" (e.g. train, street, park), and then it is combined with handcrafted audio features in an early fusion approach, in order to recognize the audio event of an unknown audio recording. Detailed experimentation proves that the proposed context-aware deep learning scheme, when combined with the typical handcrafted features, leads to a significant performance boosting in terms of classification accuracy. The main contribution of this work is the demonstration that transferring audio contextual knowledge using CNNs as feature extractors can significantly improve the performance of the audio classifier, without need for CNN training (a rather demanding process that requires huge datasets and complex data augmentation procedures).

Authors: Anwar Sumera , Liang Yan Fei , Khan Shahbaz , Gao Zhi-qiang
Published: November 2018

Dryland winter wheat in Loess Plateau is facing yield reduction due to shortage of soil moisture and delayed sowing time. Field experiment was conducted at Loess Plateau in Shanxi Province, China from 2012 to 2014, to study the effect of subsoiling and conventional tillage and different sowing dates on the soil water storage and contribution of N accumulation and remobilization to yield of winter wheat. The results showed that subsoiling significantly improved the soil water storage at 0-300 cm depth, improved the number of tillers and pre-anthesis N translocation in various organs of wheat and post-anthesis N accumulation, eventually increased the yield up to 17-36%. Delaying sowing time had reduced the soil water storage at sowing and winter accumulated temperature by about 180˚C. The contribution of N translocation to grain yield was maximum in glume+spike followed by in leaves and minimum by stem+sheath. In addition a close relationship was found between the N accumulation and translocation and the soil moisture in the 20-300 cm. Subsoiling during the fallow period and the medium sowing date was beneficial for improving the soil water storage and increased the N translocation to grain, thereby increasing the yield of wheat, especially in dry year.

Published: November 2018

O objetivo do artigo é avaliar e comparar a situação de segurança alimentar domiciliar por três diferentes métodos, em área rural de uma cidade brasileira: disponibilidade de energia alimentar em casa; estado nutricional; e percepção de insegurança alimentar. Trata-se de estudo transversal realizado com 79 famílias residentes em 19 comunidades rurais de um município de Minas Gerais, totalizando 272 moradores. Durante as visitas familiares, o estado nutricional foianalisado por antropometria, a percepção de insegurança alimentar pela Escala de Insegurança Alimentar (Ebia) e a disponibilidade de energia alimentar no domicílio por 30 dias. Os resultados mostraram que, das 79 famílias de agricultores familiares, 12,7% foram consideradas inseguras para a disponibilidade de energia alimentar, 24,0% devido à presença de baixo peso em casa e 49,5% por Ebia. Houve baixa correlação entre os métodos, com diferenças entre eles (Kendall W 0,162 p <0,001). A insegurança alimentar esteve associada à presença de pelo menos um indivíduo com idade inferior a 18 anos no domicílio. A segurança alimentar classificada de acordo com a Ebia foi associada a um aumento no número de pessoas que vivem no domicílio, na produção de vegetais e frutas. Concluiu-se que nenhum indicador isolado pode cobrir várias dimensões da segurança alimentar, a qual envolve uma abordagem ampla e multifacetada; portanto, sua avaliação completa requer diferentes métodos de classificação.

CAN ECONOMIC POLICY UNCERTAINTY PREDICT EXCHANGE RATE AND ITS VOLATILITY? EVIDENCE FROM ASEAN COUNTRIES
Authors: Phan Dinh Hoang Bach , Juhro Solikin M.
Published: November 2018

This paper studies whether the global economic policy uncertainty (EPU) predicts the exchange rate and its volatility in 10 ASEAN countries using monthly data from January 1997 to December 2017. Applying the recently developed predictive regression model of Westerlund and Narayan (2012, 2015), we discover that the EPU positively and statistically significantly predicts the exchange rate of six out of ten currencies. One standard deviation increase in the EPU index leads to a depreciation of between 0.050% and 2.047% in these currencies. Moreover, the EPU predicts the exchange rate volatility for all 10 ASEAN countries. Their exchange rate volatilities increase by between 0.107% and 0.645% as a result of a one standard deviation increase in the EPU index. These results are robust to different forecasting horizons, different sub-sample periods, and after controlling for the global financial crisis.
Adjusting the North-South Balance: Southern Judicial Boldness and its Implications for the Regulation of Global Supply Chains
Authors: Fowkes James
Published: November 2018

Modern regulators have long grappled with the challenges of regulating multinational corporations and their cross-border supply chains. There is a tendency, in this context, to view the problem as one where the most serious or common abuses are to be found in the Global South, but the effective remedies mostly need to be found in the Global North. This article discusses recent examples of expansive, creative judicial activity from India, Colombia and the African regional judicial system to challenge this assumption. Some of today’s Southern judicial activity can break the stereotype in interesting and important ways, and our thinking about regulation in this context needs adjustment accordingly.

In early 2017, one of the largest oil producer company in Thailand has dedicated a jack up drilling rig to support Well Plug and Abandonment (P&A) operations as part of the company's asset retirement program. With hundreds of Well P&A targeted, Drilling Team in the company has worked with our Business Partners and came up with new ideas and proven technologies such that the drilling rig can successfully execute and deliver high volume of P&A work, Incident Free with World Class Performance.

Introducing new P&A Technology in the Gulf of Thailand – The Abrasive Water Jet Cut, the tool provides ability to cut multiple strings of casing that usually cemented together using high impact jetting force. Company has utilized the tool to cut the Tie-back and Unconventional well (Dual Cemented Wellbore Design) where we could not effectively cut with the conventional mechanical cutter. Another key benefit is the operation can be performed offline under-rig floor which is not on the critical path resulting in rig time saving.

Adding Non-standard Fishing Equipment Portfolio is also another key to company's success. Leveraging organizational capability by adding non-standard fishing tools and services to handle well complication cases supporting Well Factory P&A operations. Introducing new innovation of the tool design increases the overall operational efficiency, such as –Increase possibility of success to set proper permanent barriers in wellbore,–Improve efficiency to verify the plug in the well with leaked surface casing,–Successful trial combination Tools for multiple operation in one run which reduce tripping time. This have impact a lot on time & cost saving to many P&A wells in our operation. Now all tools are in toolbox for utilization.–Streamline fishing service container for service and redress tools on site to minimize offshore rig deck space reducing logistics and wait on equipment time from Shore base.

In conclusion, the company can ensure that they can deliver the Asset Retirement commitment to Kingdom of Thailand and can perform the job safely and efficiency. In 2017, this rig had completed P&A activity exceeding the target well count. P&A technology had been extended the capability to support other P&A operations i.e. Infilled slot recovery and redrill for other drilling rigs.

There are three wells with poor well integrity and high sustained annulus pressure(SAP) in JZ Gasfield. In order to remove the sustained pressure, remediate the poor well integrity and abandon wells in compliance with national regulations, plans, methods and practice taken were discussed in this paper. The occurrence reasons and source of pressure were identified first. And the different remediation and treating programs were made according to evaluation of the popular and good practice around the world. The best killing and cementing method were taken. Casing strings recovered by section mill and bullhead cementing process were chosen as one of the effective plans to solve problems like this.

These three wells with sustained casing pressure were abandoned successfully and effectively. The most complicated well was dicussed in detail. Well abandonment plans for gasfield were made in detail. Abrasive waterjet cutting system were utilized first time. Lessons gained in the well plug and abandonment execution phase can be applied in other regions, especially in Asia Pacific.

A series of practice taken to handle SAP were described in this paper for the first gasfield abandonment and decommission project in China. These experiences shared both in China and other regions around the world, this could offer some help for others to handle situations like this.

Provide an overview of the procedures for abandoning onshore wells, backgrounds and technical requirements as a reference. Provide an overview of the utilization of reserved abandonment and site restoration funds to finance the abandonment of the wells.

Plugging and abandoning the well is done when it has not more potential on productivity, has a well integrity problem, and is at risk of theft and the environment. Procedures undertaken to obtain approval for the closure of the well. The technical review of abandoning of the well refers to recognized national and international standards. Discuss some possible innovations to obtain more effective way in troubleshooting or to replace some procedures that are not possible to be followed. Reserved ASR funds disbursement procedures to pay for work. Challenges to speed up the process of disbursement of funds.

Following standard procedures requires considerable attention and impacts on costs to be incurred. Disbursing ASR funds that have been reserved to pay for the work is not as easy as the established procedure. Several suggestions for improvements are made to speed work approval and disbursement of funds.

Well abandonment procedures have been standardized, but submission procedures and ASR disbursement submissions are necessary for every operator to know. This paper provides an important guide for operators to submit P&A proposals and fund disbursements.
Well Integrity, Plugging and Abandonment: Abrasive Cutting Applications for Well Severance
Authors: Anderson David
Published: November 2018

Upon cessation of production the cost of well abandonment is absorbed as a liability within the oil and gas industry under increasing financial pressure in the current climate. One of the key opportunities when undertaking a well abandonment campaign is identifying new and innovative technology available and adopting it to reduce operating time, project risk and ultimately cost. The final phase of the plugging and abandonment (P&A) is the well severance and conductor removal operation that is traditionally performed using mechanical knives for rig-based campaigns. This involves operating online, deploying on drill pipe and multiple deployments into the well to cut and recover the multi-string casing.

An alternative approach to the traditional mechanical cutting method is the use of water-abrasive cutting technology that uses a high-pressure water and abrasive mixture to sever through the well's multiple casings and conductor below mudline. Abrasive Water Jet (AWJ) cutting technology is used to cut through multi-string casing and conductors from 7″ to 36″ in a single deployment, regardless of the number of casing strings, casing weight or cement presence in the well annuli. The cutting time is between five and eight hours depending on well construction.

The water-abrasive cutting technology can be utilised during rig-based P&A campaigns where the cutting tool can be deployed offline using a standalone deployment system to sever the well below the sea-bed whilst online operations continue with the rig and well services teams, hence providing P&A SIMOPS. By operating offline, the overall rig time per platform is reduced.

The water-abrasive cutting tool also provides the solution for the removal of subsea tie-back and dual bore wells which can't routinely be cut with mechanical knives due to the knives range limitations and the risk of getting ‘stuck in hole’ and the subsequent recovery operation. The non-intrusive water-abrasive method not only provides a solution to the problematic subsea tieback wells and dual bore wells but also removes the cutting operation from the critical path of the rig.

Similarly, the water-abrasive cutting technology can be operated from a vessel or barge rather than the rig. This allows the well severance and removal phase of the P&A process to be removed from the rig's scope and the high cost asset to be off-hired as early as possible. This approach is applicable for surface wells and subsea wells alike and also allows the asset owner to combine the well severance with the platform removal phase.

Fifteen (15) subsea wells in Mauritania, consisting of 9 oil producer wells, 5 water injector wells and 1 gas injection well, were temporary suspended in preparation for plug and abandonment at a later phase. This paper describes the overview, challenges faced and lessons learnt captured during the planning and execution of pioneer deepwater decommissioning project, particularly on the subsea temporary well suspension (TWS) campaign in Mauritania.

Lack of wells production history became one of the biggest challenge during the planning for the temporary well suspension and Plug and abandonment (P&A) campaign. The remoteness of the field locations contributed to logistics difficulties. Sourcing of H2S rated equipment and drillpipe riser, integration between Xmas tree and Intervention riser system due to incompatible connector took long lead time. Barrier management was a key consideration during the planning phase for known well integrity issues, and potential lack of barrier establishment that could be encountered during operations. The difference in water depth also impacted on rig selection.

Problems encountered during the execution of the temporary well suspension campaign included H2S, annulus & tubing communication problem, high annulus pressure, non-functioning tubing retrievable surface-controlled safety valve, unexpected waxy sludge in well, blocked perforations, hydrate, brine incompatibility, difficulty in accessing well due to over-trawlable structure and dependency on FPSO for pressure monitoring prior to tree cap removal due to barrier establishment problems. The temporary well suspension campaign was executed with abandonment in mind.

Shutting the aging well for good towards the end of field life requires a lot of operational and technical considerations as well as high cost to ensure project viability and safe operation. Procedures to evaluate competent cap rock layers as natural formation barriers, well plug and abandonment (P&A) design, assurance on well barrier integrity through cement bond logging and best practices in well abandonment will be highlighted through three case studies in this paper.

Data integration starting from the early exploration or development drilling phase, during production and towards the abandonment phase play key roles in the project and will be the ultimate pinnacles in determining cap rock intervals, cement integrity, tubulars condition, potential reservoir communication and plug setting depth in the well. Adding an extensive behind casing acoustic noise, pulsed neutron and cement bond logging campaign and full integrated formation evaluation in the picture will further enhance the feasibility of abandonment project with additional discovery of shallow gas potential to prolong the field economics.

Detail analysis of petrophysical logs, mud log gas reading, well pressure monitoring, shallow gas hazard site survey and acoustic-noise log deliverables have revealed the presence of shallow gas as deep as 300-400 m below the sea bed and few more intervals at deeper or shallower depth. Incorporating all available data to date had resulted in extensive volume of gas-in-place being evaluated, thus driving additional value through potential workover or shallow gas appraisal project prior to abandonment. In addition, operational cost, time and safety will be further optimized through cap rock restoration method and cement recipe upgrading.

In a nutshell, packaging shallow gas potential and possible work-over or appraisal campaign for quick field monetization prior to abandonment will prove to justify the project economics. Changing the game from conventional gas producer to shallow hanging fruits opportunity is worth to be exploited in this case.
