The effect of various parameters such as tubing size, gas injection rate, multi-porting and gas lift valve port diameter on the performance analysis of integrated gas lift system along with the flow stability have been discussed in the paper. Field X is one of the matured offshore fields in India which has been producing for over 40 years. It is a multi-pay, heterogeneous and complex reservoir. The field is producing through six Process Complexes and more than 90% of the wells are operating on gas lift. As most of the producing wells in the field are operating on gas lift, continuous performance analysis of gas lift to optimize production is imperative to enhance or sustain production. 121 Oil wells and 7 Gas wells are producing through 18 Wellhead platforms to complex X1 of the field X. Out of these 121 oil wel...

However, the technique has not gained widespread use due to lack sufficient scientific publications that can give more insights over its use and help in designing a safe and effective treatment. This paper presents a novel transient mathematical model for design and analysis of thermochemical treatment for well flow lines by taking into account the chemical kinetics, heat transfer, fusion of wax and associated two-phase flow. The governing equations have been solved using tools of computational fluid dynamics and heat transfer (CFD - HT). The resulting simulator can be used to prepare an optimum thermochemical plan by analysing the effects of important factors including wax details, deposition profile, heat loss, formulation composition and injection strategy. Simulation results with the developed model indicate t...

Crude oil often contains paraffins which precipitate and adhere to the liner, tubing, sucker rods and surface equipment as the temperature of the producing stream decreases in the normal course of production. Conventional methods of removal of paraffin deposits include chemical dissolution, hot oil/water circulation, mechanical scrapping and pigging. As an alternate to the conventional methods of paraffin removal, wax removal by exothermic chemical reaction also known as thermochemical stimulation is the technique in which the energy liberated from a suitable exothermic reaction is utilized for melting the paraffin deposits and has been shown to be more effective than the conventional treatments in literature. A major challenge faced while execution of this technique is to control the reaction rate and provide sufficient delay time so that heati...
Kerala’s 2018 floods and landslides offer great lessons on risk governance and climate policies. ... more Kerala’s 2018 floods and landslides offer great lessons on risk governance and climate policies. The challenges in each phase of rescue, relief and rebuilding were addressed in this case study. Through the strategic use of ‘ecospatiality’, it is shown that the ‘state–society synergy’ does exist in its potentiality, although, by and large, it is ignored in already existing ‘riskscape’ scholarship. However, the context of this study proves to be an ideal site for illustrating the possibilities of actualising this latent potential through ecospatiality planning. Such attempts can, at the same time, be of local effectiveness and global significance.

Antioxidant potential by various biochemical tests (Antioxidant ability assays, total phenol content, total flavonoid content) were evaluated. The result showed that GSE exhibit high antioxidant ability assays (312.06±1.69 ìg ascorbic acid), total phenol content (190.34±2.26 mg GAE/g), total flavonoid content (83.43±2.36 mg rutin/g). The chevon nugget treated with GSE had significantly (P less than 0.05) lower thiobarbituric acid reactive substance (TBARS) and free fatty acid % (FFA) compared to control during frozen storage. Addition of GSE significantly (P less than 0.05) reduced the total plate, total psychrophilic and yeast and mold count in chevon nuggets during storage at -18±2oC. The GSE treated chevon nuggets recorded significantly (P less than 0.05) superior...

This would ensure a submerged possibility of understanding ‘workplace resistances’ and their varied dynamics. The case study involves both contemporary ethnographic and in-depth historical accounts sourced from the Dalit women’s protests at tea plantations in the south Indian state of Kerala in 2015 (along with pertinent secondary sources). The article explores how ‘self-organizing’ by the mis-organized, during the course of the struggle, turned them into active political subjects: a ‘subject position from which to speak’. Exposing certain theoretical constraints within the postcolonial approach and incorporating insights from deeper subjective aspects of the labour process, social reproduction in postcolonial perspectives, and the feminist literature on intersecti...

The content and conception of social responsibility of a business organization is discussed mainly through elaboration of the reasons for business organizations to bear and implement social responsibility. The approach to corporate social responsibility in Lithuania and Belarus is analysed and discussed by comparing the attitudes regarding a wide range of elements related to the corporate social responsibility and its implementation. The approach of business actors of the two countries is collated through different perspectives and angles.

For this survey, we have collected the data of a fixed route for 14 days and implemented various statistical methods for analyzing it. The study, focused on various junctions because these are the points, which are more prone to congestion. It aimed at finding out the critical junction and suggest improvement in them. As the number of vehicles is on the rise, it is the need of the hour to solve this problem

This is empirically informed by the narratives of the livelihood-environmental resistance launched by subalterns in the Indian state of Kerala, known for its twin legacies – of communist government and social development – which have proved to be a direct challenge to the state/corporate-led developmentalism in the region. The article thus attempts to contribute to the debate on modernity more from the perspective of resisting subjects and agents, with their particular subjective experience and understandings of science and reasoning. However, their resistance generates transformative events of universal relevance and thereby global issues of epistemology. As such, the article develops a theory of knowledge that takes subaltern resistance itself as modernity.
