Slumping crude prices and chemical sales pushed down Occidental Petroleum Corp.’s first quarter earnings.

Occidental reported first-quarter net income of $1.2 billion ($1.43 per share), a 1.5 percent dip from $1.23 billion ($1.43) for the same period a year earlier.

Sales for the Los Angeles-based oil company also slid 6.6 percent to $4.1 billion hurt by slumping crude prices near the end of the year and a 45 percent tumble in sales from the company’s chemicals business.

Shares in Oxy were down 17 cents to $51.28 in afternoon trading Tuesday on the New York Stock Exchange.
