5. A drilling monitoring and control system comprising:
a display apparatus; and
a computer comprising,
a machine control connection, the computer being configured to transmit machine control signals to at least one machine which is used to drill a wellbore via the machine control connection,
a user operable machine control input apparatus operatively connected to the computer, and
a parameter input port,
wherein,
the computer is connected to a plurality of sensors for receipt of a data stream of readings from the plurality of sensors via the parameter input port, the readings from each of the plurality of sensors providing a parameter,
the parameters are divided into a first group of parameters and a second group of parameters,
the computer is programmed to use the display apparatus to display the parameters in the first group of parameters on a first of a plurality of partially overlapping tabs on the display apparatus and to display the second group of parameters on a second of a plurality of partially overlapping tabs on the display apparatus, to compare each parameter in both the first group of parameters and the second group of parameters with at least one parameter boundary, and to use the display apparatus to display a visual alert if any of the parameters in the first group of parameters or in the second group of parameters falls outside a respective parameter boundary,
the visual alert is provided on the display apparatus in a position which is permanently visible on the display apparatus,
instructions inputted into the user operable machine control input apparatus based on the visual alert are transmitted to the computer so as to bring the parameter of the first group of parameters or the parameter of the second group of parameters back within the respective parameter boundary, and
the computer transmits the instructions, via the machine control connection, as the machine control signals, to make an operational change to the at least one machine which is used to drill the wellbore.
