Heidrun Field
upOil from the Heidrun field. The Heidrun oil field is an oil and gas field discovered in 1985 in the Norwegian sector of the Norwegian Sea, named after the goat Heiðrún from Norse mythology. The field lies north of Kristiansund. It has produced oil and gas since October 1995. In 2013, it produced 65,000 barrel of oil per day and 760 million cubic meters of natural gas. The crude oil is characterized as being naphthenic with 25.0 API (0.9043 g/cm3), 0.52% sulfur, and a high TAN (Total Acid Number) of 2.90. The Heidrun field is located on Haltenbanken in the Norwegian Sea at a depth of . The field has been developed with gas and water injection, using a floating concrete tension leg platform, installed over a subsea template with 58 well slots. The northern part of the field is developed with subsea facilities. Geology The Cimmerian structure is a southwest-plunging horst block on the southwest flank of the Nordland ridge formed in the Late Jurassic-Early Cretaceous. Produ ...

Norway
Norway, officially the Kingdom of Norway, is a Nordic countries, Nordic country located on the Scandinavian Peninsula in Northern Europe.

Total Acid Number
The total acid number (TAN) is a measurement of acidity that is determined by the amount of potassium hydroxide in milligrams that is needed to neutralize the acids in one gram of oil. It is an important quality measurement of crude oil. The TAN value indicates to the crude oil refinery the potential of corrosion problems. It is usually the naphthenic acids in the crude oil that cause corrosion problems. This type of corrosion is referred to as naphthenic acid corrosion (NAC). TAN values may also be useful in other industries where oils are used as lubricants to determine oxidation and the subsequent corrosion risk to machinery. TAN value can be deduced by various methods, including * Potentiometric titration: The sample is normally dissolved in toluene and propanol with a little water and titrated with alcoholic potassium hydroxide (if sample is acidic). A glass electrode and reference electrode is immersed in the sample and connected to a voltmeter/potentiometer. The meter ...

Oil Fields In Norway
An oil is any chemical polarity, nonpolar chemical substance that is composed primarily of hydrocarbons and is hydrophobe, hydrophobic (does not mix with water) and lipophilicity, lipophilic (mixes with other oils). Oils are usually flammable and surfactant, surface active. Most oils are unsaturated lipids that are liquid at room temperature. The general definition of oil includes classes of chemical compounds that may be otherwise unrelated in structure, properties, and uses. Oils may be animal fats, animal, vegetable oil, vegetable, or petrochemical in origin, and may be Volatility (chemistry), volatile or non-volatile. They are used for food (e.g., olive oil), fuel (e.g., heating oil), medical purposes (e.g., mineral oil), lubrication (e.g. motor oil), and the manufacture of many types of paints, plastics, and other materials. Specially prepared oils are used in some religious ceremonies and rituals as purifying agents. Etymology First attested in English 1176, the word ...
