Claim 9:
10. A control system for a managed pressure drilling system having a drill string and a drill bit extended into a wellbore, an eclectic drilling recorder system, a mud pump, and a pressure management apparatus (PMA) in communication with an annulus defined between the drill string and the wellbore, the control system being in communication with the pressure management apparatus, the control system comprising:
an onsite device in communication with a control unit of the pressure management apparatus and the electronic drilling recorder system to receive data in substantially real-time, the data being collected by a plurality of sensors of the pressure management apparatus and the electronic drilling recorder; and
an offsite device comprising:
a user interface having a display;
a control panel accessible via the display; and one or more processors in communication with the onsite device via a communication network, the one or more processors having access to a first set of instructions that, when executed by at least one of the one or more processors, causes the offsite device to: generate, on the control panel, one or more of: a hole depth indicator showing a depth of the wellbore; a bit depth indicator showing a depth of the drill bit; a block height indicator showing a remaining length to a subsequent drill string segment connection; a flow in indicator showing a pump rate of a drilling fluid entering the wellbore; a flow out indicator showing a flow rate of a drilling mud entering the pressure management apparatus; a mud weight in indicator showing a mud weight of the drilling fluid entering the wellbore; a mud weight out indicator showing a mud weight of the drilling mud exiting the wellbore; a surface backpressure indicator showing a surface backpressure; a target surface backpressure indicator showing a target surface backpressure; an intermediate casing point (ICP) pressure indicator showing an ICP pressure; and an ICP equivalent circulating density (ECD) indicator showing an ICP ECD; iteratively update the control panel to display the one or more of the hole depth indicator, the bit depth indicator, the block height indicator, the flow indicator, the flow out indicator, the mud weight in indicator, the mud weight out indicator, the surface backpressure indicator, the ICP pressure indicator, and the ICP D indicator in substantially real-time; and control the pressure management apparatus, via the onsite device, based at least in part on information displayed on the control panel;

wherein the first set of instructions further causes the offsite device to: generate, on the control panel, one or more of: a bottomhole pressure indicator showing a bottomhole pressure; a bottomhole ECD indicator showing a bottomhole ECD; a surface backpressure limit indicator showing a surface backpressure limit a surge pressure indictor showing a surge pressure; and a trip speed indicator showing a trip speed; and iteratively update the control panel to display the one or more of the bottomhole pressure indicator, the bottomhole ECD indicator, the surface backpressure limit indicator, the surge pressure indicator, and the trip speed indicator in substantially real-time;
wherein the pressure management apparatus has a first choke, wherein the first set of instructions further causes the offsite device to: generate, on the control panel: a first choke status indicator showing a status of the first choke; and a first choke position indicator showing an openness of the first choke; and iteratively update the control panel to display the first choke status indicator and the first choke position indicator in substantially real-time;
wherein the first set of instructions further causes the offsite device to: generate, on the control panel, a graphical representation displaying one or more of: the depth of the wellbore; the depth of the drill bit the remaining length; the pump rate of the drilling fluid; the flow rate of the drilling mud; the mud weight of the drilling fluid; the mud weight of the drilling mud; the surface backpressure; the target surface backpressure; the ICP pressure; the ICP ECD; the bottomhole pressure; the bottomhole ECD; the surface backpressure limit the surge pressure; the trip speed; the status of the first choke; and the openness of the first choke, for a range of block heights of the wellbore; and iteratively-update the control panel to display the graphical representation in substantially real-time;
wherein the pressure management apparatus has a second choke, wherein the first set of instructions further causes the offsite device to: generate, on the control panel, a second choke status indicator showing a status of the second choke; generate, on the control panel, a second choke position indicator showing an openness of the second choke; and iteratively update the control panel to display the second choke status indicator and the second choke position indicator in substantially real-time;
wherein the onsite device comprises a user interface having a display; an onsite control panel accessible via the display of the onsite device; and one or more processors having access to a second set of instructions that, when executed by at least one of the one or more processors of the onsite device, causes the onsite device to: generate, on the onsite control panel, one or more of: a gain/loss gauge; a surface backpressure gauge, an ICP pressure gauge; a standpipe pressure gauge; a bottomhole pressure gauge; an ICP ECD gauge; a bottomhole ECD gauge; an annular friction losses gauge; a custom depth ECD gauge; and a custom depth pressure gauge; and iteratively update the onsite control panel to display the one or more of the gain/loss gauge, the surface backpressure gauge, the ICP pressure gauge, the standpipe pressure gauge, the bottomhole pressure gauge, the ICP ECD gauge, and the bottomhole ECD gauge in substantially real-time;
wherein the first choke comprises a choke cartridge, and wherein the second set of instructions further causes the onsite device to: generate, on the onsite control panel, a choke cartridge status indicator showing whether the choke cartridge is inserted or removed; and iteratively update the onsite control panel to display the choke cartridge status indicator in substantially real-time; and
wherein the first choke cartridge indicator comprises interactive buttons to allow a position of the choke cartridge to be set by the user, and wherein the second set of instructions further causes the onsite device to control the pressure management apparatus based at least in part on the interactive buttons of the first choke cartridge indicator.
