This paper highlights the concept of complex well through various advanced or emerging technologies involved during the well life process. The current state of the art states that drilling technology is more mature than production and treatment technologies.

The well life process is divided into four phases: pre-project, conception, realisation and exploitation. Each phase is studied in terms of productivity on one side, cost on the other. New concepts such as limitation of well oversizing or anticipation of field maturity are regarded through actual examples. It is finally concluded that this technical revolution can only be a success if culture and human organisation evolve at the same rythm. Well being the most transverse object of the E&P chain, it represents a fantastic opportunity for all disciplines to work in close collaboration within integrated teams and not anymore through conventional isolated petroleum professions.
