A control system for a pressure management apparatus (PMA) of a drilling system has an onsite device in close proximity to and in communication with the PMA and an offsite device at a remote location. Both the onsite and offsite devices are connected to a network, such as the Internet, through which the devices can communicate with one another. The onsite device receives data in real-time from the PMA and the offsite device can access the data in real-time via the network. The offsite device can generate a command based on the data or user input at the offsite device and send the command to the onsite device to modify one or more settings of the PMA. A control panel is displayed on the user interface of the offsite device to allow an operator to remotely control the PMA.

A method for drilling a wellbore comprises using drilling mud having a mud weight less than the formation pore pressure while drilling the horizontal section, to release some formation gas to mix with the drilling mud. As the mixture flows up the wellbore annulus, the resulting pressure in the vertical section is within the mud weight window (MWW) of the weak zones, thereby maintaining wellbore stability without the need for intermediate casings. The wellbore is killed by introducing a volume of heavy mud via a circulation sub in the drill string and periodically introducing additional heavy mud to fill the void left behind by the drill string as it is pulled uphole. The ratio of light mud and heavy mud in the killed well is such that the resulting pressure in the vertical section is within the MWW of the weak zones.
