Business Description and Basis of Presentation [Text Block]	1. ORGANIZATION AND NATURE OF BUSINESS Blueknight Energy Partners, L.P. and subsidiaries (collectively, the “Partnership”) is a publicly traded master limited partnership with operations in 26 states. The Partnership provides integrated terminalling services for companies engaged in the production, distribution and marketing of liquid asphalt. The Partnership manages its operations through one operating segment, asphalt terminalling services. The Partnership’s common units and Preferred Units, which represent limited partnership interests in the Partnership, are listed on the Nasdaq Global Market under the symbols “BKEP” and “BKEPP,” respectively. The Partnership was formed in February 2007 as a Delaware master limited partnership. The Partnership previously provided integrated terminalling, gathering, and transportation services for companies engaged in the production, distribution, and marketing of crude oil in three different operating segments: (i) crude oil terminalling services, (ii) crude oil pipeline services, and (iii) crude oil trucking services. On December 21, 2020, the Partnership announced it had entered into multiple definitive agreements to see these segments. The transaction related to the crude oil pipeline services segment closed on February 1, 2021, the final transaction related to crude oil trucking services closed on February 2, 2021, and the transaction related to crude oil terminalling services closed on March 1, 2021. These segments are presented as discontinued operations for all periods presented. Unless otherwise noted, information in these notes to the consolidated financial statements relates to continuing operations. As the Partnership is only operating through one operating segment, a segment footnote is no longer required.
