Oil fell $1.02 to $100.82 per barrel Monday morning as traders/investors continued to lock-in profits and Saudi Arabia underscored its plans to boost production capacity, Reuters reported Monday.

The other major energy commodities were mixed in early trading Monday. Heating oil fell about 1 cent to $2.97 per gallon, unleaded gasoline rose 1 cent to $2.60 per gallon, and natural gas rose about 2 cents to $9.09 per million BTUs.

The crude oil decline Monday represents a continuation of a short-term downward trend, after oil surged more than $20 in less than two months, prompting some traders to take short-term profits, amid signs of likely slower oil demand growth in the United States.

The market early Monday was also responding to comments from Saudi Arabia, which said Sunday it is working to increase both oil production and refinery capacity in order to maintain global economic growth, according to Reuters.

Oil Analysis: The market will appreciate any comments and efforts by Saudi Arabia indicating it is striving to increase production and refining capacity. True, it takes time to increase production, but the market will take any expansion comments by the Saudis as a sign that more supply is on the way, which will lower oil prices considerably -- a welcome sight for oil importing nations and consumers.
