Shell Oil Co. has shelved plans to develop an oil-by-rail transfer facility at its refinery in Anacortes, Wash. The company says low oil prices, slow production and the project’s $95-million price tag are behind the suspension of its three-year effort to secure permits for the project, which would have included a 5,500-ft rail spur as well as facilities to unload crude oil produced in North Dakota’s Bakken fields. Currently, the 145,000-barrel-per-day facility receives most of its feedstock oil via tankers from Alaska’s North Slope.
