Abstract

A drilling system, comprising: a plurality of drilling drive systems; a fracturing drive system; a centralized power supply system electrically coupled to said drilling drive systems and said fracturing drive system to supply power thereto; and a plurality of distributed power supply systems electrically coupled to said drilling drive systems to supply additional power thereto during peak loading of a respective one of the plurality of drilling drive systems.

Claims

1. A drilling system, comprising:

a plurality of drilling drive systems;

a fracturing drive system;

a centralized power supply system electrically coupled to said drilling drive systems and said fracturing drive system to supply power thereto; and

a plurality of distributed power supply systems electrically coupled to said drilling drive systems to supply additional power thereto during a peak loading of a respective one of the plurality of drilling drive systems.

2. The drilling system of claim 1, wherein the centralized power supply system comprises a plurality of diesel engines.

3. The drilling system of claim 1, wherein the centralized power supply system comprises an aero-derivative gas turbine.

4. The drilling system of claim 1, wherein the plurality of distributed power supply systems comprise one or more gas engines.

5. The drilling system of claim 1, wherein the plurality of distributed power supply systems comprise one or more energy storage systems coupled to the centralized power supply system to store power therefrom and later apply the additional power to the plurality of drilling drive systems during the peak loading.

6. A method, comprising:

supplying additional power from a plurality of distributed power supply systems to a plurality of drilling drive systems during a peak loading of a respective one of the plurality of drilling drive systems; and

supplying power from a centralized power supply system to a fracturing drive system to fracture a formation at the wells.

7. The method of claim 6, wherein the centralized power supply system comprises a plurality of diesel engines.

8. The method of claim 6, wherein the centralized power supply system comprises an aero-derivative turbine.

9. The method of claim 6, wherein the plurality of distributed power supply systems comprise one or more gas engines.

10. The method of claim 6, wherein the plurality of distributed power supply systems comprise one or more energy storage systems coupled to the centralized power supply system, the method further comprising:

storing power in the one or more energy storage systems from the centralized power supply system; and

applying the additional power from the one or more energy storage systems to the plurality of drilling drive systems during the peak loading.
