The WAG injection project feasibility of South Flank of Central Azeri field on the basis of simulation model was studied in this thesis work. The 58 sensitivity scenarios were considered to evaluate and analyze the behavior of WAG in this field. Scenarios are based on the important WAG parameters, such as half slug size volume, cycles, WAG ratio, start time, bottomhole injection pressure etc. The Base Case is set with static and dynamic characteristic close to real field. From the scenarios calculated, the Best (Scenario 53, 9.3% incremental oil) and the Worst (Scenario 52, 3.4% incremental oil) cases were analyzed to get general view of WAG in terms of profitability in comparison to the Base Case. For more profound conviction of feasibility of the WAG project, additional cases with Simultaneous WAG injection and cases with changed permeabilities have been considered. The Best case was re-evaluated under application of Carlson&rsquo / s relative permeability hysteresis model. All results eventually were analyzed in terms of economical profitability &ndash / net present value (NPV). Economical analysis of scenarios is provided at the end of the work.

Johanson (2003: 274) refers to the grammatical categories of evidentiality found in Turkiclanguages as indirectivity, characterised “by reference to its reception by a conscious subject”.The East Old Turkic post-terminal verbal item in -miš and copula particle in ermiš are theoldest known markers of indirectivity in Turkic and have been morphologically preserved inthe West Oghuz languages. However, the topic of indirectivity in Azeri seems to have beentouched upon very sparingly in previous empirical studies. For instance, there seem to be nostudies that acknowledge the discursive context in examining the marking of indirectivity inAzeri. This thesis adopts a qualitative, corpus-linguistic discourse-analytical perspective toanalyse the functions of the verbal inflectional suffixes {-mỊš}/{-(y)ỊB-DỊ(r)} and the copulaparticle {Ị-mỊš}, and their possible indirective uses or connotations, as well as other strategiesfor marking of indirectivity, in various discourse types in speech corpora from the Azerispeaking regions of Urmia, Ardabil, and Zanjan in Iran. The analysis illustrates how the givenmarkers acquire different functions in different discourse contexts and may be used tosignalise indirectivity in Azeri. It also shows how certain lexical expressions may be used toencode and strengthen indirective readings. As such, the results of this study can be useful asa point of departure for further research in the area.

La présente étude vise à analyser la situation de plurilinguisme d’©rumiyeh, a partir d’une perspective d’<< analyse dedomaine >> (domain analysis). Trois minorités ethniques, linguistiques et religieuses vivent dans la ville, à savoir lesTurcs, les Kurdes et les Arméniens, qui s’expriment respectivement en turc, kurde et arménien. La langue nationale dupays, l’1ran, est le persan. Naturellement, la population de la région grandit avec deux ou trois langues.Pour cette étude, 900 questionnaires ont été recueillis dans toute la ville et 681 ont été sélectionnés de manière aléatoire(328 Turcs, 214 Kurdes et 139 Arméniens). Les questionnaires ont été élaborés essentiellement à partir du Modèle deFishman, avec quelques modifications importantes d’ordre culturel et régional. Le but principal de cette analyse était le<< analyse de domaine >> : il s’agissait de savoir que1le(s) langue(s) parmi le persan, le turc, le kurde et/ou l:31'l”1'lé111€I`létait dominante(s) dans les différents domaines sociaux. Les domaines sociaux ont été classés du plus infonnel ou plusformel ; ils comprennent la famille, la religion, les amitiés, le voisinage, les transactions, l’éducation et l‘administrationfl’emploi. Dans une société polyglossique, à chaque situation correspond une << haute >> (H) et une basse (L) << variété >>,et chaque variété a ses propres fonctions spécialisées. Le domaine d’analyse a été mis au point séparément pour chacunedes trois populations.Pour voir l’incidence des trois variables indépendantes choisies e l’âge, le niveau d’étude et le sexe — sur le choix de lalangue, le chercheur a appliqué différentes méthodes statistiques : le test-T et l’analyse de la variance à un facteur et àdeux facteurs (0ne-way cmd tw0—way ANOVA). Il apparaît alors que le sexe ne joue pas sur le choix de la langue maisque les deux autres facteurs connaissent quelques fluctuations dans toute la population.L’étude parvient alla conclusion que, dans la population turque, la langue de la région, le turc, est dominante dans tousles domaines sociaux. Chez les deux autres populations, à savoir les Kurdes et les Arméniens, la langue officielle, lepersan, est. dominante, avec néaimioins un usage plus fréquent dans les situations formelles. / The present study is aimed at analyzing the multilingual situation of Uimia from a domain analysis perspective. Threedifferent ethnic, Tinguistic, and religious minorities, namely Turks, Kurds, and Armenians are living in this city,speaking Turkish, Kurdish, and Armenian, respectively. The national language of the country, Lran, is Persian.Naturally, the people in this area are brought up bilingual or trilingual.To do the study, 900 questionnaires were collected from the whole city. 68l(328 Turks, 214 Kurds, and 139 Armenians)out of this were randomly selected. The questionnaires were basically adopted from Pishman's model with someimportant cultural and regional modifications. The main purpose of the study was domain analysis, i.e., to find outwhich language(s) from among Persian, Turkish, Kurdish and/or Armenian is dominant in different social domains. Thesocial domains which were hierarchically arranged from most informal to most formal ones include family, religion,friendship, neighborhood, transaction, education, and goveriunent/employment. ln each situation in a polyglossicsociety, there is a high (H) and a low (L) variety; and each variety has its own specialized functions. The domainanalysis was separately devised for each of the three different populations.To find out the effect of three independent variables of age, level of education, and sex on language choice, differentstatistical procedures of T-test, One-way ANOVA, and Two-way ANOVA were applied. While sex did not show tohave any effect on language choice, the other two factors had some fluctuations in the whole population.The study came to the_ conclusion that in Turkish population, the language of the region, Turkish, was dominant in allsocial domains. In the other two populations, namely Kurdish and Armenian, the official language, Persian, wasdominant while moving from more informa] to formal situations.
