Schlumberger is the leading oilfield services company (its primary competitors in this area are Halliburton and Baker Hughes).  But Schlumberger is more an IT company than a stereotypical iron/bricks/mortar company.  After all, finding oil & gas, and managing its efficient maximum extraction is an information-intensive challenge. Schlumberger's oilfield operations are more IT-related than anything else.

In 2006, Schlumberger's revenues were US$18 billion, and operating income exceeded US$2 billion.  Schlumberger has about 50,000 employees (representing more than 100 nationalities), and maintains permanent operations in more than 100 countries.  In 2003 the legal department had 135 professionals (27 different nationalities) in 20 countries -- most of these directly support assigned operating units.

I worked at Schlumberger from 1984 through 2004, the last eight years as deputy general counsel, responsible for substantive IT legal issues across the company, setting overall policy direction for the operating units in areas of security, privacy, web-standards, and employee/customer/vendor policies.  I also managed the legal department's "knowledge management" initiative  (which we conceived in coordination with the company's VP of KM as the first functional KM project for the entire company).  My professional c.v. is here, and there is more discussion about Knowledge Management here.
