Schlumberger Melodramatic 1930s

I do not come from a family that has a background in the oil world. It is hence safe to assume none of my folks got any clue about my job or industry in general. The video is a melodramatic version of the first resistivity log done by my company in the US. The b/w movie is taken in 1932 in California - since then both the industry and Schlumberger have come a long way and look very different.
