What is Condensate Blend?

CRW is a fully blended aggregate of many light sweet feeder streams and only begins its existence in blend tanks in Edmonton, Alberta. CRW is a fully equalized crude stream, wherein above standard feeders are compensated by substandard feeders on a net zero basis. The CRW blend is nearly completely consumed within Alberta as a diluent in heavy crude blending.
