Please refrain from making test edits in Wikipedia pages, such as those you made to List of abbreviations in oil and gas exploration and production, even if you intend to fix them later. Your edits have been reverted. If you would like to experiment again, please use your sandbox. JBW (talk) 19:44, 7 July 2023 (UTC)
