Heavy oil is defined as liquid petroleum of less than 20°API gravity or more than 200 cp viscosity at reservoir conditions. No explicit differentiation is made between heavy oil and oil sands (tar sands), although the criteria of less than 12°API gravity and greater than 10,000 cp are sometimes used to define oil sands.

Carrier oils, also known as vegetable oils, base oils or fixed oils, are used to dilute essential oils, CO2s and absolutes before applying to the skin.. View outline (sitemap) for this area. Carrier Oil Information Introduction to Carrier Oils Heavy Fuel Oil HFO, also known as “residual fuel oil”, is based on the high viscosity, tar-like mass, which remains after the distillation and subsequent cracking of crude oil in order to produce lighter hydrocarbon products, such as petrol, distillate diesel fuels and heating oil or feedstocks for lubricants. Heavy oil is defined as liquid petroleum of less than 20°API gravity or more than 200 cp viscosity at reservoir conditions. No explicit differentiation is made between heavy oil and oil sands (tar sands), although the criteria of less than 12°API gravity and greater than 10,000 cp are sometimes used to define oil sands. While properties such as viscosity, density, and boiling point may vary widely, the ultimate or elemental analysis varies over a narrow range for a large number of samples. Heavy oils are The common characteristic properties of heavy oil are: high specific gravity, low hydrogen to carbon ratios, high carbon residues, and high contents of asphaltenes, heavy metal, sulphur and nitrogen. Specialized processing is required to produce more useful fractions, such as: naphtha, kerosene, and gas oil. One of the most important properties of heavy oils for both engineering and geophysical purposes is viscosity. Viscosity is often the limiting factor in heavy oil production. As we shall see, it also has a strong influence on the seismic 752 THE LEADING EDGE JUNE 2006 Figure 6. Heavy oil bulk modulus (mixture) as a function of temperature. Heavy oil properties are strongly dependent on composition and temperature. Because of biodegradation, alkanes are destroyed and complex heavy compounds dominate. As a result, the trends for velocities, gas-oil ratios, well as for viscosities develop

Heavy crude oil is highly-viscous oil that cannot easily flow to production wells under normal reservoir conditions. It is referred to as "heavy" because its density or specific gravity is higher than that of light crude oil. Heavy crude oil has been defined as any liquid petroleum with an API gravity less than 20°. Physical properties that differ between heavy crude oils and lighter grades include higher viscosity and specific gravity, as well as heavier molecular composition. In 2010, the The major properties of heavy fuel oil are as follows; 1. Density: Density is the relationship between mass and volume at a stated temperature, and the SI unit is Kg/m 3 . This gives value of 800- 1010 kg/m 3 for marine heavy fuel oil. Since heavy fuel oils are almost universally contaminated with salts and salt water, they normally require water washing to remove the water-soluble salts of sodium and potassium. Fuel washing involves mixing heated fuel with 5–10% of potable water along with a small amount (0.02%) of an emulsion-breaking fluid to aid in separation. Heavy oil is defined as liquid petroleum of less than 20°API gravity or more than 200 cp viscosity at reservoir conditions. No explicit differentiation is made between heavy oil and oil sands (tar sands), although the criteria of less than 12°API gravity and greater than 10,000 cp are sometimes used to define oil sands. Heavy Oils – Seismic Properties Michael Batzle*, Brian Zadler, Ronny Hofmann, Colorado School of Mines De-hua Han, University of Houston Summary Heavy oil properties are strongly dependent on composition and temperature. Because of biodegradation, alkanes are destroyed and complex heavy compounds dominate. As a Heavy oils usually display a greater content of as- phaltenes and resins than conventional oils (Speight, 1991), which directly impacts recovery, transport and refining processes. Colloidal properties of as- phaltenes and resins have been the subject of intense debate in the literature - see for instance Loh et al.

Oils, fats and butters are generally classified as soft, hard or brittle. You’ll see that I did so in the soap making oil chart. Soft oils are generally oils that are liquid at room temperature such as olive oil, castor oil, sweet almond, rice bran…etc. As a general rule, soap made from a high percentage of these oils will be on the softer
