Spokesman Cameron Yost said the actual number of job reductions at the Canadian operation had not yet been finalized, adding it would be "well below" 10 percent.

The cuts were announced to Shell employees internally on Thursday.

"It's not layoffs in the traditional sense of the word," Yost said. "It's adjustments to the organizational structure."

Albian Sands is the mining portion of Shell's Athabasca Oil Sands project near Fort McMurray, Alberta, which also includes the 255,000 barrel-per day Scotford upgrader.

Last February, Shell halted work on its proposed 200,000 bpd Pierre River oil sands mine in Alberta, saying it was re-evaluating the timing of various asset developments.

Asked whether the reductions were related to the halving of global oil prices in the past six months, Yost said: "Even if oil price had remained stable we would still be looking at these areas of our business."

Global oil prices sank to their lowest level since April 2009 on Friday on persistent worry over a global supply glut.
