Abstract

A system for directing the drilling of a well at a drill-site includes an instructing unit, an instructed unit, and a central unit. The instructed unit receives drilling instruction from an instructing driller, sends drilling instructions to the central unit, and presents to the instructing driller drilling instructions and instruction confirmations received from the central unit. The instructed unit receives instruction confirmations from an instructed driller, sends instruction confirmations to the central unit, and presents to the instructed driller drilling instructions received from the central unit. The central unit stores and forwards drilling instructions and instruction confirmations to the instructing unit and instructed unit, and generates and stores slide sheet information from the drilling instructions.

Claims

1. A system for directing the drilling of a well at a drill-site, comprising:

(a) an instructing unit communicatively coupled with a central unit, the instructing unit configured to receive one or more drilling instructions from an instructing driller, send received drilling instructions to the central unit, receive one or more instruction confirmations from the central unit, and present received instruction confirmations to the instructing driller;

(b) an instructed unit located at the drill-site and communicatively coupled with the central unit, the instructed unit configured to receive one or more instruction confirmations from an instructed driller, send received instruction confirmations to the central unit, receive one or more drilling instructions from the central unit, and present received drilling instructions to the instructed driller;

(c) a central unit communicatively coupled with the instructing unit and instructed unit, comprising;

(i) a receiver configured to receive one or more drilling instructions from the instructing unit and one or more instruction confirmations from the instructed unit;

(ii) a memory having stored therein a data structure for storing received drilling instructions, received instruction confirmations, and slide sheet information;

(iii) a logger communicatively coupled to the receiver and the memory, the logger configured to store received drilling instructions and received instruction confirmations in the memory;

(iv) a slide sheet manager communicatively coupled to the receiver and the memory, the slide sheet manager configured to generate slide sheet information from the received drilling instructions and store the slide sheet information in the memory; and

(v) a transmitter communicatively coupled to the receiver, the transmitter configured to transmit received drilling instructions to the instructed unit and received instruction confirmations to the instructing unit.

2. The system in claim 1, wherein the instructing unit is located remote to the drill-site.

3. The system in claim 1, further comprising a plurality of instructing units.

4. The system in claim 1, wherein:

(a) the system further comprises an alarm unit located at the drill-site, the alarm unit configured to receive an alarm instruction from the central unit and generate an audible alarm upon receipt of the alarm instruction;

(b) the central unit further comprises an alarm manager communicatively coupled to the receiver, the alarm manager selectively configurable to issue the alarm instruction upon receipt of one or more drilling instructions by the receiver of the central unit; and

(c) the transmitter of the central unit is further configured to transmit the alarm instruction issued by the alarm manager to the alarm unit.

5. The system in claim 1, wherein:

(a) the system further comprises a monitoring unit communicatively coupled with the central unit, the monitoring unit configured to receive one or more drilling instructions and instruction confirmations from the central unit, and present received drilling instructions and instruction confirmations to a user;

(b) the transmitter of the central unit is further configured to transmit received drilling instructions and received instruction confirmations to the monitoring unit.

6. The system in claim 5, wherein the system comprises a plurality of monitoring units.

7. The system in claim 1, wherein:

(a) the instructing unit is further configured to receive slide sheet information from the central unit and present slide sheet information to the instructing driller; and

(b) the transmitter of the central unit is further communicatively coupled to the slide sheet manager and is further configured to transmit slide sheet information to the instructing unit.

8. The system in claim 7, wherein:

(a) the instructed unit is further configured to receive slide sheet information from the central unit and present slide sheet information to the instructed driller; and

(b) the transmitter of the central unit is further configured to transmit slide sheet information to the instructed unit.

9. The system in claim 1, wherein:

(a) the instructing unit is further configured to receive drilling instructions from the central unit and present received drilling instructions to the instructing driller; and

(b) the transmitter of the central unit is further configured to transmit received drilling instructions to the instructing unit.

10. The system in claim 9, wherein:

(a) the instructed unit is further configured to receive instruction confirmations from the central unit and present received instruction confirmations to the instructed driller; and

(b) the transmitter of the central unit is further configured to transmit received instruction confirmations to the instructed unit.

11. The system in claim 5, wherein:

(a) the monitoring unit is further configured to receive slide sheet information from the central unit and present slide sheet information to the user; and

(b) the transmitter of the central unit is further communicatively coupled to the slide sheet manager and is further configured to transmit slide sheet information to the monitoring unit.

12. An apparatus for facilitating the drilling of a well at a drill-site, the apparatus comprising:

(a) a receiver configured to receive one or more drilling instructions from an instructing unit and one or more instruction confirmations from an instructed unit;

(b) a memory having stored therein a data structure for storing received drilling instructions, received instruction confirmations, and slide sheet information;

(c) a logger communicatively coupled to the receiver and the memory, the logger configured to store received drilling instructions and received instruction confirmations in the memory;

(d) a slide sheet manager communicatively coupled to the receiver and the memory, the slide sheet manager configured to generate slide sheet information from the received drilling instructions and store the slide sheet information in the memory; and

(e) a transmitter communicatively coupled to the receiver, the transmitter configured to transmit received drilling instructions to the instructed unit and received instruction confirmations to the instructing unit.

13. The apparatus in claim 12, wherein:

(a) the apparatus further comprises an alarm manager communicatively coupled to the receiver, the alarm manager selectively configured to issue an alarm instruction upon receipt of one or more drilling instructions by the receiver; and

(b) the transmitter is further configured to transmit the alarm instruction issued by the alarm manager to an alarm unit located at the drill-site.

14. The apparatus in claim 12, wherein the transmitter is further configured to transmit received drilling instructions and received instruction confirmations to a monitoring unit.

15. The apparatus in claim 12, wherein the transmitter is further configured to transmit slide sheet information to the instructing unit.

16. The apparatus in claim 15, wherein the transmitter is further communicatively coupled to the slide sheet manager and is further configured to transmit slide sheet information to the instructed unit.

17. The apparatus in claim 14, wherein the transmitter is further communicatively coupled to the slide sheet manager and is further configured to transmit slide sheet information to the monitoring unit.
