Abstract

A reserve fuel system can be used to supplement fuel provided to an engine of wellsite equipment. For example, a fuel supply line can transport gaseous fuel at a wellsite to an engine of an equipment coupled to the fuel supply line. A reserve fuel tank can store gaseous fuel diverted from the fuel supply line. The reserve fuel tank can include a first valve coupling a first end of the reserve fuel tank to the fuel supply line to divert the gaseous fuel and a second valve coupling a second end of the reserve fuel tank to the engine. The second valve can be in a closed position to prevent the stored gaseous fuel from transferring to the engine or an open position to transfer the stored gaseous fuel to the engine. A control system can adjust the second valve based on a pressure of the fuel supply line.

Dependent claims

A system comprising:

a fuel supply line configurable to transport gaseous fuel at a wellsite;
an engine of an equipment coupled to the fuel supply line, the engine configurable to perform a wellsite operation at the wellsite using gaseous fuel received from the fuel supply line;
a reserve fuel tank configurable to store gaseous fuel diverted from the fuel supply line, the reserve fuel tank comprising:
a first valve configurable to couple a first end of the reserve fuel tank to the fuel supply line to divert gaseous fuel from the fuel supply line into the reserve fuel tank;
and
a second valve configurable to couple a second end of the reserve fuel tank to the engine, the second valve being positionable in (i) a closed position to prevent the stored gaseous fuel in the reserve fuel tank from transferring to the engine and (ii) an open position to transfer the stored gaseous fuel from the reserve fuel tank to the engine;
and
a control system configurable to adjust the second valve from the closed position to the open position in response to detecting that a pressure of the fuel supply line is lower than a predetermined threshold, and wherein the control system is further configurable to adjust the second valve from the open position to the closed position in response to detecting that the pressure of the fuel supply line is above the predetermined threshold.

A method comprising:

storing, by a reserve fuel tank, gaseous fuel received at a first end via a first valve from a fuel supply line transporting gaseous fuel at a wellsite to supply an engine of an equipment at the wellsite;
adjusting a second valve coupling a second end of the reserve fuel tank to the engine from a closed position to an open position;
transferring the stored gaseous fuel from the second end of the reserve fuel tank to the engine of the equipment via the open position of the second valve;
determining, by a control system, that a pressure of the fuel supply line is lower than a predetermined threshold;
and
adjusting, by the control system, the second valve to the open position based on determining that the pressure of the fuel supply line is lower than the predetermined threshold.

3 more elements

A reserve fuel tank comprising:

a tank configurable to store gaseous fuel diverted from a fuel supply line that is configurable to transport the gaseous fuel at a wellsite to an engine of an equipment configurable to perform a wellsite operation at the wellsite;
a first valve configurable to couple a first end of the tank to the fuel supply line to divert gaseous fuel from the fuel supply line into the tank;
a second valve configurable to couple a second end of the reserve fuel tank to the engine, the second valve being positionable in (i) a closed position to prevent the gaseous fuel stored in the reserve fuel tank from transferring to the engine and (ii) an open position to transfer the gaseous fuel stored in the reserve fuel tank to the engine;
and
a control system configurable to adjust the second valve from the closed position to the open position in response to detecting that a pressure of the fuel supply line is lower than a predetermined threshold, wherein the control system is further configurable to adjust the second valve from the open position to the closed position in response to detecting that the pressure of the fuel supply line is above the predetermined threshold.
