TORONTO, June 28 (Reuters) - ConocoPhillips (COP.N) said it planned to upgrade the coker at its 64,000 barrel-per-day Billings, Montana, refinery but would not give details as to when the work would begin.
"We are not specifying the details about the upgrade schedule and unit run rates beyond saying we expect to complete the work next year," said Bill Stephens, a spokesman for the company.
According to various published reports, the company is transporting two giant loads of coker drums via barge and road in a three-week journey. The first tranche will leave early July and the second in September. The cost of the upgrade is estimated at $50 million. (Reporting by Janet McGurty)
