An integrated control system (ICS) for a well drilling platform is provided, which well drilling platform has a plurality of control systems and devices. The ICS includes an ICS controller is in communication with a master control. The ICS controller includes a memory device coupled to a processor. Instructions executed by the processor cause the ICS controller to: communicate with each of the control systems to determine a status of each of the control systems; cause the master control display to display status information for at least one of the control systems; in response to an operator input perform a well drilling platform function, the function requiring a coordinated state between a first control system and at least a second control system, configure the first control system and the second control system into a coordinated state.

Integrated control system for a well drilling platform

The present invention relates to a managed pressure and/or temperature drilling system () and method. In one embodiment, a method for drilling a wellbore into a gas hydrates formation is disclosed. The method includes drilling the wellbore into the gas hydrates formation; returning gas hydrates cuttings to a surface of the wellbore and/or a drilling rig while controlling a temperature and/or a pressure of the cuttings to prevent or control disassociation of the hydrates cuttings.

Managed pressure and/or temperature drilling system and method

In one embodiment, a method for drilling a wellbore includes an act of drilling the wellbore by injecting drilling fluid through a tubular string disposed in the wellbore, the tubular string comprising a drill bit disposed on a bottom thereof. The drilling fluid exits the drill bit and carries cuttings from the drill bit. The drilling fluid and cuttings (returns) flow to a surface of the wellbore via an annulus defined by an outer surface of the tubular string and an inner surface of the wellbore. The method further includes an act performed while drilling the wellbore of measuring a first annulus pressure (FAP) using a pressure sensor attached to a casing string hung from a wellhead of the wellbore. The method further includes an act performed while drilling the wellbore of controlling a second annulus pressure (SAP) exerted on a formation exposed to the annulus.
