ABSTRACT:
A well drilled with air or gas as a circulating medium traversing pay zones with greater than normal pressures or pressures such that hydrocarbons would permeate drilling fluids and cement is drilled and completed while permitting a continuous flow of hydrocarbons from the well until it is desired to shut the well in at the surface. The intermediate casing string and the production casing string cooperate with the tubing so that the cement for the production string may be positioned without contact with the hydrocarbons.
