Enterprise Products Partners filed a new tariff for its terminal in Midland, Texas, updating quality parameters from crude deliveries out of the Permian basin, effective 1 May.
The new tariff clarifies the difference between the three Permian streams: West Texas Intermediate (WTI), West Texas Sour (WTS) and West Texas Light (WTL). The upper gravity limits for the three streams were specified as 38.1°API for WTS, 44°API for WTI and 50°API for WTL, according to the tariff filing with the Texas Railroad Commission (TRC).
The Midland terminal's tariff previously did not differentiate between the three streams and allowed for any deliveries up to 44°API.
Enterprise has also said it will update its quality sampling procedures to enforce the new specs.WTI and WTL deliveries should have a maximum sulfur content of 0.2pc, mercaptans up to 75ppm, iron up to 10ppm, and a maximum vanadium and nickel content of up to 2ppm each — not to exceed a combined 3ppm.
The new parameters align with the specifications for eligible WTI cargoes that market participants will be allowed to deliver into the North Sea Dated benchmark, which has been expanded to include the US light sweet crude as of 2 May trade.
Enterprise has also updated the rules and regulations at its Echo terminal in Houston, Texas, to align with the same quality parameters, effective 1 May.
Argus has nominated 12 US Gulf coast crude export terminals as eligible loading locations for WTI cargoes delivering into Dated Brent, including Enterprise's facilities in Houston, Freeport and Texas City.
The US crude cargoes will help bolster liquidity in the North Sea benchmark, for which production of its traditional component grades have declined sharply over the past two decades, despite the incremental additions of other European crudes.
WTI deliveries to Europe averaged roughly 1.15mn b/d in 2022, according to data by analytics firm Vortexa, compared to roughly 670,000 b/d of combined production for the five crude streams already underpinning the benchmark.
Meanwhile in the North Sea, cargo sizes for traditional benchmark component crudes Brent, Ekofisk and Forties will rise from 600,000 bl to 700,000 bl in June to align with anticipated WTI cargo volumes.
