A case in point came when Exxon Mobil (XOM) inspected a pipeline in Arkansas in February using a smart pig, only for the line to split open a month later and spill 5,000 barrels of crude. The device didn’t find the minute cracks along the seam of the pipe that caused the burst.
The boom in U.S. oil output is straining the country’s 184,000 miles of pipeline, with the volume of spillages jumping by 77% so far this year to 93,000 barrels.
Companies affected include EEQ, EEP, BKEP, MWE, KMR, KMP, SXE, EPD, PAA MMP, HEP and PSXP.
