Oil prices up ahead of US stockpiles report

Oil prices edged higher in Asian trade today as dealers await the latest US crude stockpiles data for clues about demand in the world's biggest economy at the tail-end of a harsh winter.

New York's main contract, West Texas Intermediate for April delivery, rose three cents to $101.86 in mid-morning trade. Brent North Sea crude for April was up five cents at $109.56.

"What investors are really focused on right now is an accurate picture of US demand going forward," David Lennox, resource analyst at Fat Prophets in Sydney, told AFP.

"The US has not been performing as well as we would like considering the fact that it is world's biggest economy and top oil consumer," he said.

Lennox added that demand for "finished petroleum products" such as heating oil -- which has seen increased consumption during winter -- would like taper as spring approaches.

Total crude stockpiles in the United States likely rose by about 800,000 barrels in the week to February 21, according to a survey of analysts by The Wall Street Journal.

A rise in stockpiles indicates weak demand in the United States, putting downward pressure on prices.

The US Department of Energy will release official inventory figures later Wednesday.

Analysts will also be monitoring fresh US economic data to assess the impact of months of frigid weather on its tepid recovery.
