MarkWest Energy Partners LP said Friday that its Houston Processing and Fractionation facility in southwest Pennsylvania was still shut down and will remain so until further notice. Severe thunderstorms that rolled through much of the region on Wednesday led to a lightning strike at one of the complex's three processing plants (see Shale Daily, May 29). The company said it will likely notify investors and the news media when the plant is brought back online. A company spokesman said damage at the plant was still being assessed and repairs were being made. The 355 MMcf/d facility primarily serves Range Resources Corp., which said Thursday that some of its wells were shut in as a result of the problems at the Houston plant. Some production is being rerouted to MarkWest's Majorsville complex in Marshall County, WV, about 30 miles southwest of the Houston facility in Chartiers Township in Washington County.
