Abstract
The present study is conducted within the borders of lexicographic research, where corpora have increasingly become all-pervasive. The overall goal of this study is to compile an open-source OPEC[1] Word List (OWL) that is available for lexicographic research and vocabulary learning related to English language learning for the purpose of oil marketing and oil industries. To achieve this goal, an OPEC Monthly Reports Corpus (OMRC) comprising of 1,004,542 words was compiled. The OMRC consists of 40 OPEC monthly reports released between 2003 and 2015. Consideration was given to both range and frequency criteria when compiling the OWL which consists of 255 word types. Along with this basic goal, this study aims to investigate the coverage of the most well-recognised word lists, the General Service List of English Words (GSL) (West ,1953) and the Academic Word List (AWL) (Coxhead, 2000) in the OMRC corpus. The 255 word types included in the OWL are not overlapping with either the AWL or the GSL. Results suggest the necessity of making this discipline-specific word list for ESL students of oil marketing industries. The availability of the OWL has significant pedagogical contributions to curriculum design, learning activities and the overall process of vocabulary learning in the context of teaching English for specific purposes (ESP).Keywords: Vocabulary Profiling- Vocabulary Learning- Word List- OPEC- ESPOPEC stands for Organisation of Petroleum Exporting Countries.
Highlights
The linguistic corpus, which is described by Sinclair (1991, p.171) as ‘a collection of naturally occurring language text, chosen to characterise a state or variety of a language’, had been previously used in a variety of lexicographic research studies

Summary
The linguistic corpus, which is described by Sinclair (1991, p.171) as ‘a collection of naturally occurring language text, chosen to characterise a state or variety of a language’, had been previously used in a variety of lexicographic research studies. Coxhead's (2000) AWL endeavour revolutionised corpus-informed lexical research and initiated the field of discipline-specific word lists research. Stressing the need for the compilation of such word lists, many studies have been carried out to examine the coverage of the most well-known word lists, namely the AWL and the GSL, in specific corpora. This body of investigation has yielded significant results indicating the low coverage of the AWL in specific corpus and, the need for specialisation-specific word lists (see for example, Chen & Ge, 2007; Vongpumivitch et al, 2009; Martinez, 2009)
