LONDON, Dec 11 (Reuters) - Diesel barge differentials in northwest Europe declined on Wednesday with little demand throughout the day.

Traders hoped that colder temperatures in the region in recent days would spark new buying interest, but demand for heating oil in key markets remained muted.

The International Energy Agency (IEA) warned that OECD countries this winter could face a shortage in heating oil supplies as middle distillates stocks are considerably lower than in recent years. ID:nL6N0JQ27H

"In the event of prolonged cold weather and an associated surge in heating fuel demand, these inventories could be depleted rapidly," the IEA said.

In Europe, though inventories appear tight, high consumer stocks in Germany, the region's largest heating market, will provide a buffer for any large draws in the event of prolonged cold weather, the IEA said.

Distillates stocks in the United States rose sharply over the past week to more than 118 million barrels as refinery utilisation rates continued to rise, data from the Energy Information Administration showed. [EIA/S}

Heating oil stocks nevertheless declined as demand rose with the recent cold snap that hit the East Coast.

Benchmark U.S. heating oil futures HOc1 were little changed after the IEA data as distillates stocks were still below recent years' average.

The arbitrage from the U.S. Gulf Coast to Europe remained shut as the spread between the U.S. heating oil and European gasoil futures, known as HOGO, remained too wide, traders said.

"We need a much weaker HOGO for the arbitrage to kick in. Currently it is still too strong because distillate stocks in the U.S. are low," a trader said.

Turkey's sole refiner, Tupras, this week issued a tender to buy a cargo of gasoil with 0.1 and 0.2 percent sulphur content and/or a diesel cargo for Dec. 26-28 delivery.

Tupras also issued a tender to sell a cargo of jet fuel, a trader said.
