From the impact of COVID-19 on global demand to the long-term effect of energy transition on petroleum producers and refiners, crude quality has never been more important.This is why the editorial team at S&P Global Platts has created a fourth edition of the interactive Periodic Table of Oil with new crude grades, carbon intensity values, a significant redesign and new functionality to help customers plan and make more informed decisions in rapidly changing volatile markets.The market value of a crude grade has traditionally been defined by its density and sulfur content, but as the oil sector looks to better understand the emissions associated with producing different grades, carbon intensity could emerge as an important characteristic.Platts Analytics has started evaluating the carbon intensity of crude production across 104 fields. The results show a wide spectrum, from as low as 1.56 kg of carbon dioxide equivalent per barrel of production for Norway's Johan Sverdrup field, up to 175 kgCO2e/b for the San Joaquin basin in California.There are hundreds of different grades and varieties produced around the world, from light sour Murban in the UAE to Norway's light-sweet Ekofisk and Mexican heavy-sour Maya crude.This interactive chart allows readers to find key information in one place on region of origin, price, trade volumes, sulfur content, viscosity, carbon intensity, trade flows and benchmarks.The latest update as of February 2022 includes:-New carbon intensity tool, focusing on upstream emissions of some oil fields-New production and price data for 150 of the world's most traded crude grades-New WAF tab to key assessments discovery tool-Improved functionality – shifted to D3.JS-Significant style redesign-Removed refineries tabClick here to access the interactive Platts Periodic Table of Oil Platts Periodic Table of Oil has been selected as a finalist in the 66th Annual Jesse H.
