Abstract

A system for powering wellsite surface equipment comprises at least one prime mover in communication with a fuel source for powering the prime mover and having at least one heat source, at least one pump arranged to be driven by the prime mover, the at least one pump in fluid communication with at least one wellbore and at least one fluid for use in the wellbore, and at least one auxiliary system in communication with the heat source from the at least one prime mover.

Claims (26)

1. A system for powering wellsite surface equipment, comprising:

at least one prime mover in communication with a fuel source for powering the prime mover and having at least one heat source, wherein the prime mover is selected from the group consisting of a compression ignition reciprocating engine, a spark ignition reciprocating engine, a fuel cell, and a turbine engine;

at least one pump arranged to be driven by the prime mover, the at least one pump adapted to introduce at least one fluid for use in at least one wellbore and be supplied at least one fluid from the at least one wellbore; and

at least one auxiliary system in communication with the heat source of the at least one prime mover, wherein the at least one auxiliary system comprises a heat exchanger configured to transfer heat from the heat source to the at least one fluid from the at least one wellbore, to boil off a portion of the at least one fluid from the at least one wellbore from another portion of the at least one fluid from the at least one wellbore.

2. The system of claim 1 wherein the fuel source is a combustible gas fuel source.

3. The system of claim 2 wherein the combustible gas fuel source is selected from the group consisting of natural gas supplied directly from the wellbore, natural gas supplied by a producing well, natural gas supplied from a production facility, and combinations thereof.

4. The system of claim 2 wherein the combustible gas fuel source is selected from the group consisting of compressed natural gas (CNG), liquefied natural gas (LNG), natural gas from a pipeline or storage field, compressed hydrogen, compressed propane, liquefied butane, and combinations thereof.

5. The system of claim 1 wherein the fuel source comprises a liquid fuel.

6. The system of claim 1 wherein the at least one pump is selected from the group consisting of a positive displacement plunger pump, a centrifugal pump, a progressing cavity pump, and combinations thereof.

7. The system of claim 1 wherein the heat source is selected from the group consisting of an exhaust gas outlet, a prime mover cooling system, an auxiliary cooling system, and combinations thereof.

8. The system of claim 1 wherein the auxiliary system comprises a waste heat driven refrigeration system.

9. The system of claim 1 further comprising a noise reduction system.

10. The system of claim 1 further comprising an air inlet for supplying the prime mover with a source of air, the air inlet comprising an air heat exchanger for cooling or heating the source of air.

11. The system of claim 10 wherein the air heat exchanger is in fluid communication with the auxiliary system.

12. The system of claim 1 wherein the fluid for use in the wellbore is selected from the group consisting of a fracturing fluid comprising at least one of a fluid and a proppant, an acid, a cement slurry, a gravel pack mixture, a drilling fluid, a completion fluid, a compressed gas, and combinations thereof.

13. A method, comprising:

providing a system for powering wellsite equipment, the system comprising at least one prime mover in communication with a fuel source for powering the prime mover and having at least one heat source, at least one pump arranged to be driven by the prime mover, the at least one pump adapted to introduce at least one fluid for use in at least one wellbore and be supplied at least one fluid from the at least one wellbore, and at least one auxiliary system in communication with the heat source of the at least one prime mover;

positioning the wellsite equipment and system adjacent the wellbore; and

performing at least one well services operation in the wellbore with the wellsite equipment;

wherein the prime mover is selected from the group consisting of a compression ignition reciprocating engine, a spark ignition reciprocating engine, a fuel cell, and a turbine engine; and

wherein the at least one auxiliary system comprises a heat exchanger configured to transfer heat from the heat source to the at least one fluid from the at least one wellbore, to boil off a portion of the at least one fluid from the at least one wellbore from another portion of the at least one fluid from the at least one wellbore.

14. The method of claim 13 wherein the well services operation is selected from the group consisting of a fracturing operation, an acid treatment operation, a cementing operation, a well completion operation, a sand control operation, a coiled tubing operation, and combinations thereof.

15. The method of claim 13 wherein the fuel source comprises a combustible gas fuel source.

16. The method of claim 15 wherein the combustible gas fuel source is selected from the group consisting of natural gas supplied directly from the wellbore, natural gas supplied by a producing well, natural gas supplied from a production facility, and combinations thereof.

17. The method of claim 15 wherein the combustible gas fuel source is selected from the group consisting of compressed natural gas (CNG), liquefied natural gas (LNG), natural gas from a pipeline or storage field, a compressed combustible gas, a liquefied hydrocarbon gas, and combinations thereof.

18. The method of claim 13 wherein the heat source is selected from the group consisting of an exhaust gas outlet, a prime mover cooling system, an auxiliary cooling system, and combinations thereof.
