An in situ upgrade would allow an operating system, firmware or application to be upgraded while the system was still running, perhaps without the need to reboot it, depending on the sophistication of the system.
How do oil companies get thicker heavier oil out?
Temperature can also be important in freeing oil from underground reservoirs. In some oil reservoirs (in much of California, for example) the oil is thicker and heavier. To heat heavy oil in a reservoir, oil companies boil water in huge pressure vessels on the surface and send the steam down wells.
What is oil upgrading?
Upgrading means using fractional distillation and/or chemical treatment to convert bitumen so it can be handled by oil refineries. At a minimum, this means reducing its viscosity so that it can be pumped through pipelines (bitumen is 1000x more viscous than light crude oil).
What is the difference between heavy oil and conventional oil?
In comparison with heavy oil, light or “conventional” oil flows naturally and can be pumped without being heated or diluted. Heavy oils typically are not recoverable in their natural state through a well or by ordinary production methods. Most require heat or dilution to flow into a well or through a pipeline.
What is insitu process?
In-situ means “situated in the original, natural, or existing place or position.” An in-situ process processes data where it is stored such as in solid-state drives (SSDs) or memory devices like NVDIMM, rather than sending the data to a computer’s central processing unit (CPU).
What is the difference between in vivo and in situ?
In vivo refers to experiments when a live organism is used. The term in vivo is Latin for ”within the living. In situ refers to experiments that occur in a lab context that focus on a specific protein or gene, looking at it inside an entire organism.
How many years oil do we have left?
World Oil Reserves The world has proven reserves equivalent to 46.6 times its annual consumption levels. This means it has about 47 years of oil left (at current consumption levels and excluding unproven reserves).
What makes heavy oil heavy?
Chemical properties Heavy oil is asphaltic and contains asphaltenes and resins. It is “heavy” (dense and viscous) due to the high ratio of aromatics and naphthenes to linear alkanes and high levels of NSOs (nitrogen, sulfur, oxygen and heavy metals).
What is heavy oil upgrading?
UPGRADING. Upgrading is a process by which bitumen is transformed into light/sweet synthetic crude oil (SCO) by fractionation and chemical treatment, removing virtually all traces of sulphur and heavy metals.
What is partial upgrading?
The Government of Alberta defines partial upgrading as a process that reduces the thickness of oil sands bitumen so it can flow through pipelines more easily, without it having to be blended with diluent or as much diluent (a thinning agent). Partial upgrading is different from full upgrading.
Is heavy oil oil sands?
Potential as a crude oil source Of the world’s total oil resources, about 21 percent are heavy oils and about 30 percent are tar sands, though not all of these resources are considered recoverable. The development of heavy oil and bitumen reserves is increasing around the world.
What is the viscosity of heavy oil?
10,000 centipoises
In 2010, the World Energy Council defined extra heavy oil as crude oil having a gravity of less than 10° and a reservoir viscosity of more than 10,000 centipoises. When reservoir viscosity measurements are not available, extra-heavy oil is considered by the WEC to have a lower limit of 4° API.
What is in situ upgrading technology?
In addition to traditional EOR methods, such as chemical, steam, and gas flooding, in situ upgrading technology has been used to develop heavy oil and bitumen reservoirs to change the physical and chemical properties of heavy crude oil within the reservoir.
What is the difference between traditional EOR and in situ upgrading?
Traditional EOR methods used within heavy oil reservoirs only temporarily change the oil flow; crude oil recovers to its original state when the external factors are removed. Unlike traditional EOR methods, in situ upgrading technology permanently refines the crude oil in the reservoirs.
Can in situ enhanced oil recovery (EOR) boost heavy oil development?
With the growing demand of oil worldwide, heavy oil has increasingly become vital in the world energy market. However, further development of heavy oil reservoirs are limited by regular enhanced oil recovery (EOR) methods. In situ upgrading technology provides potential for the development of heavy oil and bitumen reservoirs.
How to process heavy crude oil?
These methods process heavy crude oil using three main mechanisms: increasing short-chain hydrocarbons, reducing asphaltene, and removing heteroatoms. Till date, the in situ upgrading techniques have evolved in various categories.
