North America's energy production boom is prompting firms to set aside funding for pipelines and other infrastructure to transport oil and natural gas, observers say. Since the current U.S. pipeline network wasn't developed to accommodate the new production sites, companies are seeking innovative ways to move hydrocarbons, including through tanker trains and barges. "Now we have this tectonic shift where we can become an energy surplus nation. That means we have to transform, upgrade and rearrange our logistics," said Joseph Stanislaw, an independent senior energy adviser to Deloitte.
