Halliburton Co., the world's No. 2 oilfield services company, expects the conflicts in the Middle East and North Africa and weather-related events in North America and Australia to trim first-quarter earnings.

The conflicts in North Africa and the Middle East, particularly the sanctions on Libya, will cut earnings by 3 to 4 cents per share, while the seasonal impacts of weather will be at the high end of 5 to 8 cent per share effect typically seen, it said.

Analysts have on average forecast Halliburton would report first quarter earnings of 61 cents per share, according to Thomson Reuters I/B/E/S.

Earlier on Monday, larger rival Schlumberger Ltd said the North African and Middle Eastern turmoil would trim earnings by 8 to 10 cents per share.
