Oil prices fell in Asian trading Thursday as the dollar climbed, but traders said the outlook was for further gains amid worries about global supplies, according to AP. Midday in Singapore, light, sweet crude for July delivery was down 91 cents at US$135.47 a barrel in electronic trading on the New York Mercantile Exchange. Oil prices rose sharply Wednesday after the U.S. Energy Department said oil inventories fell 4.6 million barrels last week. Analysts surveyed by energy research firm Platts expected a much smaller decline of about 1.4 million barrels. The contract jumped US$5.07 to settle at US$136.38 a barrel Wednesday after reaching as high as US$138.30.
