Global consultant Accenture is acquiring Schlumberger Business Consulting for an undisclosed sum to expand its upstream business. The 11-year-old Schlumberger Ltd. unit, which employs about 250 people worldwide, helps operators refine and manage strategies, operations, workers, capital projects and mergers/acquisitions. Accenture has a workforce of more than 300,000. "The upstream oil and gas sector is undergoing a fundamental transformation, partly driven by oil price volatility, but also by increased regulation and technology advances," said Accenture Resources Group CEO Jean-Marc Ollagnier. "This acquisition will enhance our capabilities in helping clients navigate these challenges with a combination of business, digital and technology know-how that differentiates us in this global market." The transaction requires regulatory approval.
