The function of development wells is to “effectively and efficiently recover maximum
hydrocarbon from the reservoir in a reasonable production lifetime, maximizing
economic return and resource recovery within necessary environmental limits.” These
development wells not only include producing oil and gas wells, but may also include gas
injection, water injections, and other types of service wells, to optimize the development
of the reservoir. Some wells which are to be used as producing wells for the first several
years may converted in injections wells later in the life of the reservoir, according to this
development plan.
