Thesis structure. This research includes annotation in Romanian, English and Russian, 183 pages basic text, consisting of an introduction and four chapters, general conclusions and recommendations, bibliography with 172 titles, five annexes, assumption of responsibility, curriculum vitae.

The field of study covers semiotics, semantics and pragmatics (English).

Purpose and objectives of the thesis. Exploration and investigation of the Specialized Language from the perspective of designating realities in the of oil and gas field; classifying the lexicon from the oil field into functional-semantic fields and microfields; correlation and analogy of the terms between various referential concepts underlying the cognitive metaphors; researching and describing the semantics of lexical units concerned in order to identify and determine the specific particularities and the way the technical lexicon function in the selected corpus; establishing some characteristics of the Specialized Language according to functional-semantic fields.

Scientific novelty and originality: It is proposed to fill in a current gap regarding the Specialized Language from the oil and gas field at the level of Romanian language by developing a glossary of terms as an expression of the English for Specific Purposes (ESP) problem; it is carried out a comparative-contrastive study on the development of the lexicon in the petroleum field at the level of Romanian language by conducting a fundamental investigation on the ESP from the perspective of metasemic designation of the technical elements based on motivation, in the light of some general pragmatic and semantics concepts, together with a professional decoding of the oil and gas industry terminology from different functional-semantic fields. It is proposed to highlight the unique semantic and structural features of the Technical English (TE), as well as some linguistic interferences between General Language (GE) and Specialized one.

The result obtained that contributes to solving an important scientific problem. A glossary of specialized lexicon in the oil and gas field has been developed as an expression of the ESP problem, which is theoretically studied in terms of its motivation, occurence, existence and use, first of all within the foreign languages teaching. Given the fact that engineers need an English designated to their technical needs and skills, we present an analytical approach of the lexical units from an external perspective, following the identification and decoding of the semantic and pragmatic correspondence between English terms and those in the specialized Romanian technical language.

Theoretical significance. There have been determined the perspectives on how the lexicon from petroleum industry field is developing along with the evolution of human being and technology; the correlation between General and Specialized Lexicon is followed; the semantic and conceptual characteristics of the oil and gas industry technical lexicon of the two idioms are set.

The applicative value of the paper represents the possibility of applying the results of the research in the process of using the technical lexicon for preparing different pre-university and university papers or textbooks for studying English for Specific Purposes and, in particular, for writing bilingual and general dictionaries in the oil and gas industry, as well as to elaborate some specific and optional courses.

Implementation of scientific results. The results of the research have been reflected on a number of 19 scientific articles and works presented within national and international conferences.
