Question: how much does it cost to build a small oil refinery?
Answer: Haas explained that when calculating the cost to build refineries, the industry's jargon represents it as a cash amount per barrel of oil. “For many years, refinery cost to build was about US$10,000 to a barrel and then it changed and rose to about US$20,000 and about today it could be up to US$25,000”, he observed.
