Welcome to The Cove, mcnulty1.
Identification is always a requirement. The product must be identified, even it is an amorphous raw material. Remember, the oil and gas coming from the well will undergo some low level processing, scrubbing, filtering, monitoring (H2S) etc. before pumped downstream.
Traceability is another story. If you don't have to be concerned with the hydrocarbons coming from a specific well or field, you could claim a valid exclusion.
Remember that oil comes in many varieties and some fetch much higher prices per barrel. It behooves you to properly identify the oil grade so you get properly reimbursed for the commodity.
