Low-pressure, low-producing natural gas wells commonly encounter liquid loading during production. Because of the decline in the reservoir pressure and the flow capacity, wells can fall below terminal velocity. Identifying and predicting the onset of liquid loading allows the operators to plan and prepare for combating the liquid loading hence saving valuable reserves and downtime. The present industrial applications of artificial lift, wellhead pressure reduction by compressor installation at the wellheads and reduction in tubing size are costly and often intermittent. The thesis examines the above aspects to generate a workflow for identifying and predicting the liquid loading conclusively and also assessing the application of Auger Tool and foam combination towards achieving a cost effective and more efficient solution for liquid unloading. In chapters I-IV, I describe the process of using production surveillance software of Halliburton Digital Consulting Services, named DSS (Dynamic Surveillance Software), to create a workflow of identifying the liquid loaded wells based on well data on daily basis for field personnel and engineers. This workflow also decides the most cost effective solution to handle it. Moreover, it can perform decline analysis to predict the conditions of liquid loading. In chapters V-VIII of the thesis, I describe the effort of handling the problem of liquid loading in a cost effective manner by introduction of an inexpensive Auger Tool in the bottomhole assembly and using WhiteMax surfactant soapstick from J&J Solutions. Four different combinations of well completion and fluid were tested for performance in respect to liquid hold up, pressure loss in the tubing, unloading efficiency and critical flow requirement. The test facilities and instruments, along with the operational methods, are discussed in chapter VI. Except for the reduction of the operational envelope with the inclusion of Auger Tool, the performance improved with the insertion of Auger Tool. The best combination of Auger and foam system could be a result of flow modification by the Auger Tool caused by reduced pressure loss and increase in drag coefficient and also by reduced density and surface tension of foam.

In the works of Weber, Freud, and Foucault we find a distinct depiction of the relation between the self and modern civilization. This thesis describes that relation as "entrapment": the self has become mired in the life orders of modernity and is unable to reign over them. The primary hazard of these orders is their imposition of subjectivities that are highly circumscribed, subjectivities more responsive to external functions and imperatives than to the expression of individuality. Underlying this outlook is a new consciousness of time; in lieu of evolutionary and progressive theories of history, a tragic view emerges. History is seen as devoid of any deterministic necessity, yet its collective products have become too weighty and entrenched to allow for radical, over-arching political transformations. The thesis examines how, beginning with these shared presuppositions, Weber, Freud, and Foucault develop very different understandings of entrapment, understandings that pose fundamental challenges to one another.

This study is centered on the social question as addressed and defined by Ernst Troeltsch (1865--1923) and by Max Weber (1864--1920); it pertains mainly to the rise of religious modernity and its conditions of possibility; based on a comparative analysis of the socio1ogy of religion of Troeltsch and Weber, it deals with the question how religious modernity has to be thought from a sociological perspective. / Along with modern historical science and scientific rationality in general, the social question challenged religion in the nineteenth century; this study brings out the originality of Troeltsch's vision of a modernity compatible with belief in the future of religion. / Motivated by the debate on the social question, Troeltsch's concern was the social foundations of the Christian doctrine in its relation to secular domains of activity, and this calls for a new outlook on the issue of the relation between religion and culture. / Eventually, the comparative approach of the sociological thought of Weber and Troeltsch pursued in the present work, while providing new insight into Weber's views on religion, brings about a better understanding of Troeltsch as a theologian and a philosopher of religion.

This study examines two interconnected and as yet wholly neglected aspects of Max Weber's 'Sociology of Law,' namely, its substantive underpinnings and focal concern with the status of the judge. At the heart of the 'Sociology of Law' is a comparative analysis of the Continental and the English administrations of justice, which can best be understood when read against his substantive sociology and which requires an assiduous reading of the 'Sociology of Law.' Thus the first part of this examination elucidates Weber's overarching concern with the effects of bureaucratization on the development of personality. The second part provides a detailed explication of the 'Sociology of Law' which privileges his treatment of the Common Law and distinguishes the juristic and sociological strands of his analysis, re-examines his notion of formal and substantive rationality, pays close attention to his assessment of the Free Law Movement, and accords due place to his discussion of the anti-formalistic tendencies in modern law. Taken together, these expose the contradictions and assumptions which frame his tendentious analysis and bring to light the vital role he ascribes to the judge.
