What is Platts American GulfCoast Select?

CONTACT US TO LEARN MORE >

Platts AGS reflects the value of light sweet crude oil loading 15-45 days forward on an FOB basis from locations along the US Gulf Coast including Houston, Corpus Christi, Beaumont, Nederland, Texas City, and Port Arthur, with the most competitive location on a cargo-size normalized basis setting the price assessment.

This crude oil assessment reflects a typical cargo size of 700,000 barrels, with bids, offers and trades between 550,000 and 800,000 barrels eligible for use in the assessment but normalized to reflect the freight economics of the typical cargo size. The assessment reflects the Platts WTI Midland grade supplied directly from the Permian Basin on the BridgeTex, Longhorn, Midland-to-Echo I/II, Cactus I/II, EPIC, Gray Oak, and Permian Express pipelines with API between 40 and 44 and .2% sulfur limit, among other specifications.
