Occidental Petroleum Corp. said that production has resumed in some parts of its Elk Hills oil and natural-gas field, less than a week after a fire shut down nearly 95 percent of the facility.

The Los Angeles-based oil company didn’t specify how much gas or oil the field was generating. It is the largest natural gas producer in the state.

The facility produced 70,000 barrels of oil and natural-gas liquids and 280 million cubic feet of gas annually before a pipeline leak caused a fire on Feb. 6. Occidental owns a 78 percent stake in the field.

Shares in Oxy closed up 61 cents on Tuesday to $46.60.
