Oil prices were little changed on Thursday after rising to a near one-week high in the previous session, as an industry report showing a buildup in U.S. crude stockpiles pressured the market.

Brent futures were up 34 cents, or 0.5%, at $76.38 a barrel by 1407 GMT. U.S. West Texas Intermediate crude rose 26 cents, or 0.4%, to $72.51.

Oil prices edged lower on Thursday because of the stock build in the U.S., said Saxo Bank analyst Ole Hansen.

"The market continues to lack a clear direction, with supply disruptions in Kazakhstan and the OPEC+ production increase delay being offset by global demand worries," Hansen said.

Separately, Russia said Caspian Pipeline Consortium oil flows, a major route for crude exports from Kazakhstan, were reduced by 30%-40% on Tuesday after a Ukraine drone attack on a pumping station.

A 30% cut would equate to the loss of 380,000 barrels per day of market supply, Reuters calculations show.

However, other factors and potential boosts to oil supply added to concerns about prices.

Potential restarts of oil flows from Iraq's Kurdistan region were offsetting supply risks, analysts at ING said in a note.

Turkey, which hosts the port of Ceyhan that loads the Iraqi oil from the Kurdistan region, did not receive confirmation from Iraq on the resumption as of Thursday, the country's energy minister told Reuters.
