Russia's war in Ukraine has impacted every corner of the oil market.

With redirected oil flows, supply disruption and a market increasingly under pressure from energy security concerns and demand destruction, the quality of oil has never been more important.

The medium sour barrel -- the most frequently processed oil in refineries -- has experienced the biggest change in oil flows.

This is why the editorial team at S&P Global Commodity Insights has created the 5th edition of the interactive Periodic Table of Oil with new crude grades, carbon intensity values, a design refresh and enhanced technology 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 is emerging as an important metric in price discovery.

S&P Global now evaluates the carbon intensity of crude production for almost 100 oil fields. The results show a wide spectrum, from as low as 1.67 kg of carbon dioxide equivalent per barrel of production for Norway's Johan Sverdrup field, up to 527 kgCO2e/b for the Orinoco Belt in Venezuela.

There are hundreds of different grades and varieties produced around the world, from light sour Murban in the UAE to Guyana's medium sweet Liza 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 2023 includes:

• New carbon intensity data, focusing on upstream emissions of some oil fields
• New production and price data for 150 of the world's most traded crude grades
• New colour palate and significant redesign
• Improved functionality – shifted to D3.JS
