The article presents the stages and problems of conceptual design of metaphorical oil and gas terminology, which is rapidly developing in recent decades, so the purpose of the article is to define the principles of conceptual design of metaphorical terminology and to present some empirical evidence for this. The methodological basis of the article consists of methods that are widely used in linguistics: definitive and cognitive analysis, observation and description of linguistic facts. When considering the structural and semantic characteristics of metaphorical terms, the modeling method and the etymological method were used. The article presents and explains: 1) the main areas of cognitive sources of metaphorical terms in the oil and gas sector and the conceptual structures of metaphorical terminology developed from sources such as human, animal, spatial, medical, coloristic and other areas, which have shown different effectiveness in comparison; 2) Evaluation types, such as Effective Evaluation, Cognitive Evaluation, and Subliminal Evaluation to identify examples of oil and gas terms under study.
