"Midstream" refers to the segment of the oil and gas industry that focuses on the transportation, storage, and processing of crude oil, natural gas, and natural gas liquids. This phase occurs between the upstream sector, which involves exploration and production, and the downstream sector, which includes refining and distribution to consumers. Midstream operations typically include pipelines, storage facilities, and processing plants. Companies in this sector play a crucial role in ensuring that energy resources are efficiently moved from production sites to refineries or distribution points, making them essential for the overall energy supply chain.
