The Electro-Magnetic (EM) method is a newly developed technology aiming at heavy oil and in-situ bitumen production in an environmentally friendly way with smallest possible surface footprint. This paper outlines the process of the development of the new EM technology for heavy oil and in-situ bitumen production. It documents the step-by-step approach following the roadmap from the white-paper technology analysis to the commissioning and performing of field tests. A reservoir simulation example is provided for in-situ production with EM-heating. The current status of the technology is R&D; pilot operation is expected from 2012/13 on.
