Abstract

The present disclosure is directed to a hydraulic fracturing system for fracturing a subterranean formation. In an embodiment, the system can include an electric pump fluidly connected to a well associated with the formation, and configured to pump fluid into a wellbore associated with the well at a high pressure so that the fluid passes from the wellbore into the formation and fractures the formation. The system can further include one or more ancillary units associated with the fluid pumped into the wellbore. The system can further include a first motor electrically coupled to the electric pump to operate the electric pump, and one or more second motors, each of the second motors electrically coupled to each of the ancillary units to operate the one or more ancillary units.

Claims (29)

1 . A chemical additive system configured to provide chemical additives for hydraulic fracture treatments, the chemical additive system comprising:

a chemical additive trailer;

chemical pumps installed on the chemical additive trailer, the chemical pumps being configured to pump chemical additives from one or more chemical sources to a blender disposed on a blender trailer for addition to a fracturing slurry produced by the blender trailer, the blender comprising a mixing tub that receives the chemical additives from the chemical pumps and a proppant auger that transports a proppant into the mixing tub;

electric motors installed on the chemical additive trailer and configured to drive the chemical pumps; and

a variable frequency drive (VFD) housing installed on the chemical additive trailer, the VFD housing comprising variable frequency drives configured to control the electric motors.

2 . The chemical additive system of claim 1 , wherein at least one of the chemical pumps is a redundant chemical pump configured to operate in the event that another chemical pump fails.

3 . The chemical additive system of claim 1 , comprising a dozen chemical pumps installed on the chemical additive trailer.

4 . The chemical additive system of claim 1 , wherein each of the electric motors is configured to drive a respective one of the chemical pumps.

5 . The chemical additive system of claim 1 , wherein the chemical additive system is configured to operate as a secondary source of chemical additives for the blender trailer.

6 . The chemical additive system of claim 1 , wherein the chemical additive system is configured to operate as a tertiary source of chemical additives for the blender trailer and a hydration trailer.

7 . The chemical additive system of claim 1 , wherein at least one of the chemical pumps is configured to pump a viscosifier additive to the blender trailer.

8 . The chemical additive system of claim 1 , further comprising the blender trailer, wherein the blender trailer comprises additional chemical pumps configured to provide other chemical additives for addition to the fracturing slurry.

9 . The chemical additive system of claim 1 , further comprising:

a discharge manifold fluidly coupled to the mixing tub and at least one fracturing pump;

a suction manifold that is fluidly coupled to the mixing tub.

10 . A method for providing chemical additives for hydraulic fracture treatments, the method comprising:

operating chemical pumps installed on a chemical additive trailer to pump chemical additives from one or more chemical sources to a blender disposed on a blender trailer for addition to a fracturing slurry produced by the blender trailer, the blender comprising a mixing tub that receives the chemical additives from the chemical pumps and a proppant auger that transports a proppant into the mixing tub;

operating electric motors installed on the chemical additive trailer to drive the chemical pumps; and

operating variable frequency drives installed on the chemical additive trailer to control the electric motors.

11 . The method of claim 10 , wherein operating the chemical pumps comprises operating at least one of the chemical pumps as a redundant chemical pump configured to operate in the event that another chemical pump fails.

12 . The method of claim 10 , wherein operating the chemical pumps comprises operating a dozen chemical pumps.

13 . The method of claim 10 , wherein operating the electric motors comprises operating each of the electric motors to drive a respective one of the chemical pumps.

14 . The method of claim 10 , wherein operating the chemical pumps comprises operating the chemical pumps as a secondary source of chemical additives for the blender trailer.

15 . The method of claim 10 , wherein operating the chemical pumps comprises operating the chemical pumps as a tertiary source of chemical additives for the blender trailer and a hydration trailer.

16 . The method of claim 10 , wherein operating the chemical pumps comprises operating at least one of the chemical pumps to pump a viscosifier additive to the blender trailer.

17 . The method of claim 10 , comprising operating additional chemical pumps installed on the blender trailer to provide other chemical additives for addition to the fracturing slurry.

18 . The method of claim 10 , further comprising:

introducing the chemical additives to the mixing tub through a suction manifold;

discharging the fracturing slurry from the mixing tub through a discharge manifold.
