Along the way there are quite a few integral steps. The upstream part of the industry involves the first phase of finding and drilling oil, the midstream phase involves shipping and storing the oil, and the downstream phase involves refining and distributing the processed oil-based products.
Definition of Upstream. The upstream stage of the production process involves searching for and extracting raw materials. The upstream part of the production process does not do anything with the material itself, such as processing the material. This part of the process simply finds and extracts the raw material. Thus, any industry that relies on the extraction of raw materials commonly has an upstream stage in its production process.
