Abstract

A method of handling a short tubular on a drilling rig. The drilling rig includes a drill floor, a short tubular storage apparatus on which a short tubular is arranged, a vehicle which moves and transports the short tubular storage apparatus on the drill floor, and a tube handling apparatus having a base supported by the drill floor, an arm with a first end pivotally mounted on the base and a second end on which a pick up tool is mounted, and an actuator which pivots the arm relative to the base. The pick up tool holds the short tubular. The method includes using the vehicle to transport the short tubular storage apparatus to a location on the drill floor, and operating the actuator to move the pick up tool to engage the short tubular, to lift the short tubular, and to move the short tubular on the drill floor.

Abstract

An integrated well construction system for constructing a well includes equipment controllers which control drilling equipment, and a process controller operatively connected to the equipment controllers. The process controller includes a drilling control module which defines an operational drilling scheme and a task manager module. The operational drilling scheme has a first part to control the drilling equipment, a second part with manual tasks and/or automated tasks to be performed, and a relation between an execution of control of the drilling equipment via the first plan and of manual tasks and/or the automated tasks via the second plan. The task manager module has a user interface, a task refinement component which updates the second part, and a user interaction device which provides a manual addition of new manual tasks and/or new automated tasks, and a removal or amendment of at least one of the manual tasks and/or the automated tasks.

Abstract

A drilling plant management system includes a database having information of equipment items on a drilling rig and in a well, a controller having a processor, and a tracker module. The information includes an identification and a location of each of the equipment items on the drilling rig or in the well. The controller receives update messages with the identification of an equipment item and information related to the equipment item, and updates the database with the information in the update message. Via the processor, the controller tracks a location of each of the equipment items and, once handled by a handling equipment, transmits an update message to the database with the identification of the equipment item and the location of the equipment item.

Abstract

A drilling system includes machines, process sensors, and a drilling ECU. Each machine has machine sensor which senses an operating state and an operating range with a lower and upper limit. Each process sensor has a process sensor value and a process range with a lower and upper limit. The drilling ECU includes a data processing apparatus and a memory. The memory includes a process model with expected values of the process sensors as a function of a drilling depth, and a reservoir model with geological data. The drilling ECU receives the process sensor value and the operating state, calculates first differences between the process sensor values and the upper limit and/or the lower limit of the process range, calculates second differences between the operating state and the upper limit and/or lower limit of the operating range, and displays the first and second differences on a drilling screen.

Abstract

A lifting arm arrangement for lifting a pipe includes a pipe stacking tool comprising a first end, a second end, and a pipe handling head arranged at the second end. The pipe handling head is configured to grip around the pipe. A gripper head is connected to the first end of the pipe stacking tool. A tilt shaft is configured to connect the pipe stacking tool and the gripper head so as to form an articulated joint. The articulated joint comprises a locked position in which the pipe stacking tool is prevented from tilting about the tilt shaft, and a neutral position in which the pipe stacking tool is allowed to tilt about the tilt shaft.
