The American Petroleum Institute (API) is the only national trade association that represents all aspects of America’s oil and natural gas industry. Our more than 600 corporate members, from the largest major oil company to the smallest of independents, come from all segments of the industry. API Gravity Definitions: Definition of API Gravity of water provided by WikiPedia: The American Petroleum Institute gravity, or API gravity, is a measure of how heavy or light a petroleum liquid is compared to water. if its API gravity is greater than 10, it is lighter and floats on water; if less than 10, it is heavier and sinks. Since 1929, API’s Weekly Statistical Bulletin (WSB) has reported total U.S. and regional crude inventories and data related to refinery operations, as well as the production, imports, and inventories of the four major petroleum products: motor gasoline, kerosene jet fuel, distillate fuel oil, and residual fuel oil. An API well number or API number is a "unique, permanent, numeric identifier" assigned to each well drilled for oil and gas in the United States. The API number is one of many industry standards established by the American Petroleum Institute.Custody of the API Number standard was transferred in 2010 to the PPDM Association
After decades of decline, crude oil production in the United States has recently been increasing rapidly. Horizontal drilling and multistage hydraulic fracturing are now utilized to access oil and natural gas resources from shale rock formations that were previously either technically impossible or uneconomic to produce. Classification according to the API degree: Light crude oil: API gravity higher than 31.1 °API (less than 870 kg/m³) Medium crude oil: API gravity from 31.1 °API to 22.3 °API (870 to 920 kg/m³) Heavy crude oil: API gravity from 22.3 °API to 10 °API (920 to 1000 kg/m³) Overview. Crude oil sampling for custody transfer, fiscal, allocation or quality measurement purposes should be performed in accordance with sampling standards of ISO 3171, ASTM D 4177, API 8.2 and IP 6.2.These standards dictate a number of key design issues and steps that must be considered to ensure a system fully complies with the standards.
API stands for the American Petroleum Institute, which is the major United States trade association for the oil and natural gas industry. The API represents about 400 corporations in the petroleum industry and helps to set standards for production, refinement, and distribution of petroleum products. The American Petroleum Institute (API) is the only national trade association that represents all aspects of America’s oil and natural gas industry. Our more than 600 corporate members, from the largest major oil company to the smallest of independents, come from all segments of the industry. API gravity express the gravity or density of crude oil and liquid petroleum products. API is devised jointly by the American Petroleum Institute and the NIST - National Institute of Standards and Technology.The measuring scale is calibrated in terms of degrees API. API Gravity can be calculated as: In the international petroleum industry, crude oil products are traded on various oil bourses based on established chemical profiles, delivery locations, and financial terms. The chemical profiles, or crude oil assays, specify important properties such as the oil's API gravity.The delivery locations are usually sea ports close to the oil fields from which the crude was obtained (and new fields What Are The Crude Oil Classification? API classifies crude oil into 4 categories depending on their API Gravity range: Light – API > 31.1. Medium – API between 22.3 and 31.1. Heavy – API between 10 and 22.3. Extra Heavy – API < 10.0 (heavier than water) The system was developed by the American Petroleum Institute. An API well number can have up to 14 digits. The first two digits are the state code, the next three digits are the county code, the next five digits respresent the unique identification number for the well, and sometimes you will see an additional two digits that represent a sidetrack code and another two digits that represent a sequence of events.
13 May 2019 Oil surrendered some of its gains after an industry report was said to show a big jump in U.S. crude and refined products supplies, undermining 27 Jan 2020 U.S. petroleum exports hit a new all-time high of 9.0 million barrels per day (mb/d ) in the final month of 2019, according to data released today Using API gravity to calculate barrels of crude oil per metric ton. In the oil industry, quantities of crude oil are often measured in metric tons. One can calculate the approximate number of barrels per metric ton for a given crude oil based on its API gravity: The American Petroleum Institute reports inventory levels of US crude oil, gasoline and distillates stocks. The figure shows how much oil and product is available in storage.The indicator gives an
