Early AI Applications at Schlumberger

Schlumberger was one of the early companies to invest in artificial intelligence (AI). In this article, we summarize the work done on AI applications in the first twenty years of that investment. We highlight contributions to the company's well-known oilfield services business, as well as the technology businesses it has since divested. We also include contributions beyond Schlumberger, a bibliography of publications, and reflections from our personal experience.
