Multiscale Modeling of the Åre 6.2 Thief Zones in the Heidrun Field: Its Potential for Fluid Flow Predictions
No full textThe upper reservoir intervals of the Lower Jurassic Åre Formation in the Heidrun Field (Offshore mid-Norway) are very heterolithic and have the lowest oil recovery factor of the field despite significant amounts of remaining reserves. One of these reservoir zones is the formation Åre 6.2, which is mainly composed of tide-dominated heterolithic channel belt deposits. It contains particular layers that have excellent properties with permeabilities up to 10 Darcy. These layers are predicted to affect the production results as they can act as ‘thief zones’ within the low permeable heterolithic facies causing large quantities of water to flow through, leading to poor sweep efficiency and early water breakthrough. This study focuses on constructing conceptual depositional models of the Åre 6.2 and building detailed geological models to investigate the effect of the thief zones on overall fluid flow predictions.Conceptual depositional models were constructed by determining the characteristics of the reservoir and its depositional environment. Seven cored wells were used as the primary data to interpret lithofacies and facies associations. The study showed that Åre 6.2 mainly consisted of structured sandstones and heterolithic lithofacies with features that indicate that tidal process play an important role in the deposition. The influence of tidal process on deposition is further exemplified by the identification of two different types of channel facies associations, which are tidal and distributary channels. The thief zones were found in both facies associations, suggesting that the thief zones were formed during high freshwater discharge into the channels supplying coarse sandy material influx during a phase of high-energy deposition. To make detailed models of the tidal and distributary channels, multiscale modeling techniques were utilized to better represent the reservoir heterogeneities at the lithofacies and facies association scales.At the lithofacies scale, models were built in SBEDTM and the upscaled values of each lithofacies were obtained by applying the Representative Element Volume (REV) concept. The upscaled values were then used as input in the facies association scale models in order to represent the heterogeneities at the lithofacies scale to the next heterogeneity level. This step is essential since heterogeneities at a smaller scale may affect reservoir flow properties. Two different channel models were built in ReservoirStudioTM based on the conceptual depositional model and using outcrop analogue data from the Gule Horn Formation (Neill Klinter Group) in the Albuen area (Greenland). Flow-based upscaling was used to analyze the model uncertainties and determine a proper upscaling grid size. Finally, streamline simulations were performed to identify the effect of the thief zones. The simulation confirms that the thief zones influence fluid flow in the reservoir zone significantly as most flow was concentrated in the thief zones.Petroleum Engineering and Geo-science
Adapting authoritarianism: institutions and co-optation in Egypt and Syria
No full textThis PhD thesis compares Egypt and Syria’s authoritarian political systems. While the tendency in social science political research treats Egypt and Syria as similarly authoritarian, this research emphasizes differences between the two systems with special reference to institutions and co-optation. Rather than reducibly understanding Egypt and Syria as sharing similar histories, institutional arrangements, or ascribing to the oft-repeated convention that “Syria is Egypt but 10 years behind,” this thesis focuses on how events and individual histories shaped each states current institutional strengthens and weaknesses. Specifically, it explains the how varying institutional politicization or de-politicization affects each state’s capabilities for co-opting elite and non-elite individuals.
Beginning with a theoretical framework that considers the limited utility of democratization and transition theoretical approaches, the work underscores the persistence and durability of authoritarianism. Chapter two details the politicized institutional divergence between Egypt and Syria that began in the 1970s. Chapter three and four examines how institutional politicization or de-politicization affects elite and non-elite individual co-optation in Egypt and Syria. Chapter five discusses the study’s general conclusions and theoretical implications.
This thesis’s argument is that Egypt and Syria co-opt elites and non-elites differently because of the varying degrees of institutional politicization in each governance system. Rather than view one country as more politically developed than the other, this work argues that Syria’s political institutions are more politicized than their Egyptian counterparts. Syria’s political arena is, thus, described as politicized-patrimonialism. Syria’s politicized-patrimonial arena produces uneven co-optation of elites and non-elites as they are diffused through competing institutions. Conversely, the Egyptian political arena remains highly personalized as weak institutions and individuals are manipulated and molded according to the president’s ruling clique. This is referred to as personalized-patrimonialism. As a consequence, Egypt’s political establishment demonstrates more flexibility in ad hoc altering and adapting its arena depending on the emergence of crises.
This study’s theoretical implications suggest that, contrary to modernization and democratization theory’s adage that institutions lead to a political development, politicized institutions within a patrimonial order actually hinder regime adaptation because consensus is harder to achieve and maintain. It is within this context that Egypt’s de-politicized institutional framework advantages its top political elite. In this reading of Egyptian and Syrian politics, Egypt’s personalized political arena is more adaptable than Syria’s. These conclusions do not indicate that political reform is a process underway in either state
Creep in Oedometer for Marine Clay Soil
No full textA series of soil investigation including laboratory and in-situ tests has been carefully done to expand the
understanding of marine clay behavior around the coastal region of Malaysia. Around this country coastal
region, several researches had been conducted to investigate the soil properties of marine clay soil. Due to
rapid development in this developing country, there are a great number of construction involving marine
clay soil at the coastal region. Deformation of marine clay soil is one of the important factors that engineers
need to predict before the construction began and a lot of studies on clay deformation had been conducted.
However, the studies of long term deformation of soil or creep is certainly been neglected. The deformation
of soil due to creep condition over the constant load is a major challenge for soil engineering. In
geotechnical engineering studies, soil will deform over time when it is subjected to certain loading. Thus,
the author highlight the interest to study the geotechnical properties of marine clay at Sarawak Field and
creep behavior of this marine clay sample under various constant loading where oedometer tests were
conducted to determine the creep pattern in marine clay sample
Menyoal Wacana Perluasan Waktu Haji (Studi Kritis atas Pemikiran MasdarFarid Mas’udi)
No full textThis article criticizes Masdar Faried Masudi’s viewed that the implementation of the pilgrimage should not be done only once, ie 9 to 13 Dzulhijjah, but can be implemented for several times within a three-month span. The view is based on the many difficulties (masyaqqah) and several tragedies that occur during the Haj season because Muslims around the world run wukuf and throw jumrah at the same time and time. The argument proposed by Masdar is the timing of the three-month pilgrimage time and the coincidence of the implementation of the pilgrimage of the Messenger of Allah (peace and blessings of Allah be upon him) which coincided with the 9th Dzulhijjah. After the author conducted an analysis of the hadiths of the Prophet about the pilgrimage, the Prophet’s statement that Hajj was the Arafah, not a coincidence but was one of the provision of Hajj, so that anyone who performs Hajj must be present at Arafah, otherwise the Haj is not valid. Attendance on Arafah also became consessus of agreement among the scholars. Second, the three-month period is indeed an area of ijtihad. Meanwhile the views of the scholars on the specificity of the Hajj on September 9-13, in addition to the direct practice of the Prophet, are also the takhsis (specifity) of the context of the pilgrimage towards the general perspective of Qur’an, thus having a reasoned consideration rational and theological that become stronger than just a scholar’s ijtihad (independent exertion of jurist in finding solutions
Tax Court in Indonesia: System and Principles of Rechmatigheid and Doelmatigheid Testing
Full text linkThe Tax Court is defined as a judicial institution with legal authority as per Law Number 14 of 2002. However, upon closer examination, there are two judicial systems in various legal countries: the unity of jurisdiction, which is adopted by rule of law countries, where only one set of courts exists without recognizing the existence of administrative courts (including tax courts), and the duality of jurisdiction, which recognizes the existence of administrative and state administrative courts. These two systems not only differ in the organizational structure of the courts but also in legal substance and procedural law. In Indonesia, research shows that the judicial system is unique. When viewed from the perspective of the court\u27s organizational structure, it is closer to the unity of jurisdiction system, but in terms of court principles or dispute resolution procedures, it aligns more with the duality of jurisdiction system. Therefore, the author concludes that Indonesia\u27s judicial system is a mixed system
STRATEGY OF POST- CRISIS ECONOMIC DEVELOPMENT: A COMPARATIVE STUDY BETWEEN MEDINA CITY STATE 622-623 AND TURKEY 2008-2009
No full textAbstract The European crisis emerged in 2008 and got worse in 2009. Triggers the onset of European crisis is because Greece has defaulted on debt. The Government of Greece that is already too much owed finally dragged the countries in the European Union into a terrible crisis. Turkey, as one of the country's largest trading partner Europe also dragged into crisis in Europe. That impact affected the economic growth of Turkey which previously showed positive growth. The resolving crisis done Turkey have in common with the way the Prophet in the developing economy of Medina when the early Muslims doing Hijra from Makkah to Medina in the year 622-623. The author tried to compare the strategies of Prophet and Turkey in tackling the impact of the crisis and build the economy of the country so as to successfully compete in the global market. The purpose of this research is to provide an overview of knowledge how Turkey to cope with the impact of the European economic crisis and became one of the countries with good economic growth in the future compared with the strategies of Prophet in building the economy of Medina. This research using the method of comparative analysis in comparing Turkey's strategy in tackling the crisis and strategies of Prophet in the developing economy of Medina. While the data collection method used is by way of a research library (library research). Library Research is looking for a wide range of information, news analysis, concepts of experts thought the result embodied in books, journals, articles, internet, print-related themes. Research results based on research libraries prove that the strategy that carried Turkey to cope with the impact of the economic crisis in Europe have in common with the strategies of Prophet Muhammad in building the economy of Medina. By utilizing natural resources, building new markets and do political contracts with neighboring countries and played an important role in regional politics and make useful of the strategic location of the country, Turkey managed to cope with the impact of the European crisis and this strategy into solutions that are able to bring Turkey to the brink of success in building the economy of the country. Key Words: European Crisis, Turkey’s Economy, Strategy of Rasulullah, Comparative Stud
