Company History

MJ Systems is in reality two separate corporations. The Canadian company is headquartered in Calgary, while the US corporation operates out of Denver. The marketing, sales, production and distribution of products has been consolidated by the two corporations to simplify client interactions.

Founded in 1971, MJ Systems revolutionized the oil & gas industry with the introduction of microfiche well logs. In the 1990's MJ Systems introduced Raster Image Well Logs to the industry and has continued to deliver affordable, effective services to thousands of users – ranging from individual geologists to some of the world’s top exploration companies.
