Abstract: A drilling rig includes a drill floor with a well center opening, a derrick having a drilling machine which is suspended above the well center opening, a pipe supply area which is arranged adjacent to the well center opening on the drill floor, and a pipe handling machine. The pipe supply area has at least one pipe rack which horizontally stores pipe sections. The pipe handling machine moves at least one of the pipe sections between a horizontal storage position in the at least one pipe rack and a vertical position or a substantially vertical position above the well center opening.

Abstract: A method for scheduling a maintenance event for a machine used in drilling which includes providing a first well plan for a first well to be drilled over a first time period (tA) and a second well plan for a second well to be drilled over a second time period (tB), controlling a first computer program module for determining a projected first duty profile for the machine in the first time period and a projected second duty profile for the machine in the second time period, controlling a second computer program module for scheduling a maintenance event (tM1) for the machine based on the projected first duty profile and the projected second duty profile, and creating a new maintenance event (tM2) at a time prior to the second time period if the maintenance event (tM1) falls within the second time period.

Abstract: A method for analyzing a drilling operation includes obtaining a first set of logged operational data from the drilling operation through a first time interval, obtaining a set of operational activity dividers that delimit second time intervals within the first time interval, allocating one of a plurality of pre-defined activities to each of the second time intervals, wherein a first activity is one of the plurality of pre-defined activities, calculating a first performance indicator parameter for the second time intervals which have been allocated to the first activity, generating a time-dependent profile of the first performance indicator parameter for the second time intervals, and outputting at least one calculated value of the first performance indicator parameter to an operator. The first performance indicator parameter is calculated as a function of a duration of a respective second time interval which has been allocated to the first activity.
