* Conoco says Wood River fire impacted one unit
* Refinery expansion is 78 percent complete
TORONTO, April 29 (Reuters) - ConocoPhillips’s (COP.N) 306,000 barrel per day joint venture Wood River refinery in Roxana, Illinois, is up and running after an early morning fire in a unit associated with gasoline-making was extinguished, a company spokesman said on Thursday.
The refinery’s fire crew put out the fire quickly and there were no injuries or offsite impact, he said.
“The refinery remains in operation with the exception of the unit experiencing the fire, the S-Zorb unit, which removes sulfur from gasoline,” said Bill Stephens, a spokesman for Conoco, which operates the refinery.
The refinery is jointly-owned by ConocoPhillips and Canada’s Cenovus Energy Inc (CVE.TO).
Cenovus executives said on Thursday the coker and refinery expansion, aimed at boosting capacity to process Canadian heavy crude, is 78 percent complete. They said ConocoPhillips is due to reassess the costs in May, but do not expect major changes to the current estimate of about $3.6 billion.
