<article><p>BP is this week ramping up rates on its largest crude unit following unscheduled repairs at its 410,000 b/d refinery in Whiting, Indiana. </p><p>The company today said fuel production would "ramp up over time" and that the rest of the refinery continued to operate. </p><p>BP shut the unit on 8 August for unplanned repairs, and at the time offered no timeline for its return. </p><p>The outage sent Chicago gasoline prices rocketing higher and smothered West Canadian Select (WCS) crude prices. <i>Argus</i> assessments immediately following the outage climbed higher by 44.75¢/USG for regular Chicago CBOB and by 48.75¢/USG for regular Chicago RBOB. </p><p>Differentials for WCS, the heavy crude BP reconfigured its refinery to process over the past three years, fell to $20.75/bl in the wake of the outage, its widest discount in more than a year, based on <i>Argus</i> assessments. Both gasoline and heavy crude prices returned to more normal levels as confidence in a restart grew.</p><p>eb/tdf</p><p><br> Send comments to <a href="mailto:feedback@argusmedia.com" target="_parent"> feedback@argusmedia.com </a></p><p><u><a href="http://www.argusmedia.com/Info/General/News" target="_TOP"> Request more information </a></u> about Argus' energy and commodity news, data and analysis services. </p><p><i> Copyright © 2015 Argus Media Ltd - <a href="http://www.argusmedia.com/" target="_TOP"> www.argusmedia.com </a> - All rights reserved. </i></p></article>
