We are one of the world's leading marketers of crude oil and oil products, Through Astron Energy, we are a leading supplier of petroleum products in South   11 Mar 2015 investigation identified gaps in important crude oil characterization data, from a table of assay data for Bakken and non-Bakken crude oils  The Relationship Between Oil Prices and Economic Growth Essay. From the middle of twentieth century, due to exceptional importance of the crude oil in the supply of the world's energy demands, it has become one of the major indicators of economic activities of the world.

Assays with narrower cuts improve estimates of product properties. Many crude oil properties blend in complex ways. A too-wide cut can lead to significant miss-prediction of product properties. Understanding the crude assay and how it affects refinery economics and operation is critical to a profitable refinery. The full assay would have information on metals concentration, salt concentration, vapor pressure, etc. What the two assays above tell us is that one is light (the higher the API gravity – a measure of density – the lighter the crude) and one is heavy. It also tells us that one is sweet (low sulfur %) and one is sour. Crude oil assays of three important Mexican export crude oils-Maya, Isthmus, and Olmeca-have been updated. Most of Mexico's reserves are in the Gulf of Campeche and in the Mesozoic area of the states of Tobasco and Chiapas. The crude assays and other supplementary information in this website are provided for informational purposes only. The material is not advice on or a recommendation on any of the matters described. The material is not an offer or solicitation by or on behalf of BP p.l.c. or any of its affiliates. It is important to account for the lighter paraffin components found in the oil to arrive at the characterization factor for the entire crude. Relationship between crude oil gravity and characterization parameter. Fig. 1 depicts a relationship between crude oil gravity and characterization parameter. While not definitive, it can be observed that lower gravity crudes tend to be more naphthenic, while higher-gravity crudes tend to be more paraffinic. This is course on Plant Simulation will show you how to setup hypothetical compounds, oil assays, blends, and petroleum characterization using the Oil Manager of Aspen HYSYS. This is helpful for students, teachers, engineers and researchers in the area of R&D, any element contained in this web site.

A crude oil assay is the chemical evaluation of crude oil feedstocks by petroleum testing laboratories. Each crude oil type has unique molecular and chemical characteristics. No two crude oil types are identical and there are crucial differences in crude oil quality. The results of crude oil assay testing provide extensive detailed hydrocarbon analysis data for refiners, oil traders and producers.
