Extraction and Handling Challenges Bringing thick oil to the surface requires specialized techniques that differ significantly from standard drilling. Conventional refineries designed for light crude often struggle with the high metal and sulfur content of these feeds.
Upgrade Processes Enhancing Thick Oil Quality
In the case of oil sands, mining or in-situ extraction is necessary to separate the bitumen from sand and clay. The refining process yields a higher percentage of residual products like lubricants and asphalt, while requiring significant energy input to drive the cracking processes that transform heavy feedstocks into lighter, more marketable products.
This inherent thickness is primarily due to a higher concentration asphaltenes and resins, which are complex, large-molecule compounds that resist flow and complicate extraction and refining processes. Moreover, the energy-intensive nature of extraction and upgrading leads to higher greenhouse gas emissions per barrel compared to conventional oil.
Enhancing Thick Oil Quality Through Advanced Upgrade Processes
Specialized conversion units, such as cokers and hydrocrackers, are required to break down the heavy molecules into gasoline, diesel, and jet fuel. Defining Viscosity and Density in Crude Oil The fundamental distinction of thick oil lies in its physical behavior, specifically its viscosity and density.
