Meet the oil world’s most secretive operator: Schlumberger. It’s ubiquitous in fossil fuel operations across the world, has more staff than Google, turns over more than Goldman Sachs, and is worth more than McDonald’s — yet you won’t have heard of it. Operating largely behind the public face of oil and gas producers, the company supplies the technical backbone of hydraulic fracturing across shale basins. State regulators have cited the firm for environmental violations in certain jurisdictions, including improper waste handling and permit noncompliance. Even the most expansive service companies accumulate a regulatory record as drilling scales.
