The World’s Most Viscous Oils
Viscosity is a crucial property of oils and is a measure of their resistance to flow. In the world of oils, viscosity determines how easily they can be pumped, transported, and used in various applications. Some oils possess extraordinarily high viscosities, making them unique and potentially valuable resources. In this summary, we will explore some of the most viscous oils found around the globe.
1. Bitumen: Bitumen, also known as asphalt or tar, is arguably the most famous and viscous oil. It is a naturally occurring, highly sticky and dense form of petroleum. Found in vast quantities in Canada, Venezuela, and other regions, bitumen has a viscosity tens of thousands of times greater than that of water. Due to its thick consistency, bitumen is commonly used in road construction, waterproofing, and asphalt production.
2. Extra Heavy Crude Oil: Alongside bitumen, extra heavy crude oil represents a significant portion of the world’s most viscous oils. It is typically characterized by high density and high viscosity. Producing extra heavy crude oil involves employing specialized techniques such as steam-assisted gravity drainage (SAGD) and cyclic steam stimulation (CSS). Venezuela’s Orinoco Belt and Canada’s oil sands are major sources of extra heavy crude oil.
3. Cold Lake Blend: Cold Lake Blend, often referred to as CLB, is a mixture of bitumen and heavy oil found in Canada’s oil sands deposits. It is known for its exceptionally high viscosity, rivaling that of bitumen. CLB has a significant market demand due to its refinery capabilities and use in various oil blending operations.
4. Maya Crude: Mexico’s Maya crude is renowned for its high viscosity, although it falls slightly below that of bitumen. Maya crude is heavy and sour, meaning it contains a significant amount of sulfur. The oil is frequently blended with lighter oils to reduce its viscosity and improve its marketability.
5. Melange Crude: Another highly viscous oil on our list is the Melange crude from Azerbaijan. Melange is a blend of oil, mud, and rock, which occurs naturally in the muddy geological formations of Azerbaijan’s onshore oil fields. This unique combination gives Melange a remarkably high viscosity, presenting challenges for extraction and transportation.
6. Tia Juana Light Crude: Found in Venezuela, Tia Juana Light Crude is a heavy, viscous oil that requires specific refining processes to reduce its density and viscosity. It is often blended with lighter oils to enhance its flow properties. Despite its high viscosity, Tia Juana Light Crude remains a valuable resource due to its considerable reserves.
7. Boscan Crude: Boscan crude is a heavy oil that is extracted from fields located in Venezuela. It is known for its high viscosity and challenging production process. Boscan crude is primarily used in the production of fuel oil and asphalt.
8. Lloydminster Heavy Blend: The Lloydminster Heavy Blend is a combination of heavy oil and diluent. It is produced in the Lloydminster region, which straddles the border between Alberta, Canada, and Saskatchewan, Canada. The blend consists of heavy oil with a high viscosity, requiring dilution with lighter oils for refining and transportation.
9. Cold Heavy Oil Production with Sand (CHOPS): CHOPS is a unique method of extracting heavy oil combined with sand. It involves artificially creating a high-permeability channel in the reservoir, allowing the oil to flow with the assistance of gravity drainage. The heavy oil, along with the sand, results in a highly viscous mixture that requires specialized techniques for extraction.
10. Merey Crude: Merey crude, also known as Zuata crude, is a heavy oil found in Venezuela’s Orinoco Belt. It is a widely known and valuable resource due to its high viscosity and significant reserves. Merey crude is commonly used in blending operations to enhance the properties of lighter oils.
In conclusion, the world is home to a variety of highly viscous oils that possess unique challenges and opportunities. Bitumen, extra heavy crude oil, and cold heavy oil production with sand are among the most widely recognized and economically important viscous oils. Various extraction and refining techniques have been developed to harness the potential of these oils and make them usable for different applications. Understanding the characteristics and properties of these oils is vital for efficiently extracting, transporting, and utilizing them.The World’s Most Viscous Oils: Challenges and Opportunities in the Business Sector
