| In one embodiment, a method for drilling a wellbore includes injecting drilling fluid through a drill string disposed in the wellbore and rotating a drill bit disposed on a bottom of the drill string. The drilling fluid includes a liquid and a gas. The drilling fluid is injected at the surface. The drilling fluid exits the drill bit and carries cuttings from the drill bit. The drilling fluid and cuttings (returns) flow to the surface via an annulus formed between the drill string and the wellbore. The liquid is injected at a rate so that a liquid velocity of the returns in the annulus is sufficient to transport the cuttings. The method further includes drilling through at least a portion of a non-productive formation. | ||||||

| Method for controlling bottomhole pressure in a borehole during managed pressure drilling. In the drilling procedure fluid is circulated down a drillstring and and to surface through an annulus between the drillstring and an inner-wall of the borehole. A compressor/pump is used to inject gas into the returning drilling fluid at a gas injection point. The method comprises receiving a target bottomhole pressure;determining actual bottomhole pressure during the procedure;and adjusting a variable as directed by a feedback controller,which operates to reduce the difference between the target pressure and the measured pressure. The manipulated variable may be one or any combination of: (1)pressure of drilling fluid at the entry of the fluid into the drillstring, (2) the flow rate of drilling fluid out of the drillstring into the annulus, (3)pressure of the gas exiting from the compressor, and (4) the injection rate of the gas. | ||||||

| The present invention relates to air drilling and an apparatus, system and process for air storage for speeding up and making the air drilling process in a wellbore more efficient. The present air storage system is used to divert high pressurized air from the air compressors into an air storage tank for storage during drilling process of adding another piece of pipe to the well. In the present invention, the compressed air can be stored in the air storage system until the connection is made and the driller is ready to resume drilling. This high pressurized, large volume of stored air in the air storage system helps the compressors quickly build up enough air to resume the drilling process thus reducing the amount of drill downtime during the process of making a new pipe connection in a well. | ||||||
