Abstract
A modular pump skid includes a base, a prime mover mounted on the base, and one or more hydraulic pump circuits removably mounted on the base and operationally coupled to the prime mover, wherein each hydraulic pump circuit has a hydraulic pump operationally coupled to the prime mover and a hydraulically driven pump fluidly coupled to the hydraulic pump. Each hydraulic pump circuit is in a closed loop independent of other hydraulic pump circuits.
Claims20
A modular pump skid, comprising:
- a base;
- a prime mover mounted on the base;
- and
- one or more hydraulic pump circuits removably mounted on the base and operationally coupled to the prime mover, wherein each hydraulic pump circuit comprises:
- a hydraulic pump operationally coupled to the prime mover;
- and
- a hydraulically driven pump fluidly coupled to the hydraulic pump,
- wherein the hydraulic pump and the hydraulically driven pump are in a closed loop;
- wherein each hydraulic pump circuit is independent of other hydraulic pump circuits.

A system, comprising:
- one or more modular pump skids, comprising:
- a prime mover mounted on a base;
- one or more hydraulic pump circuits removably mounted on the base and operationally coupled to the prime mover, wherein each hydraulic pump circuit comprises:
- a hydraulic pump;
- and
- a hydraulically driven pump fluidly coupled to the hydraulic pump,
- wherein each hydraulic pump circuit is in a closed loop independent of other hydraulic pump circuits;
- one or more high-pressure fluid conduits coupled to the hydraulically driven pump;
- and
- a fluid manifold coupled to a well, wherein the one or more high-pressure fluid conduits is fluidly coupled to the fluid manifold,
- wherein the hydraulically driven pump is configured to inject fluids into the well.
8 more elements
A method, comprising:
- independently powering at least two hydraulic pump circuits on a modular pump skid with a single prime mover mounted on the modular pump skid, wherein each hydraulic pump circuit comprises a hydraulic pump and a hydraulically driven pump fluidly coupled to the hydraulic pump;
- providing horsepower, with the prime mover, to each hydraulic pump of the hydraulic pump circuits;
- redistributing an unused horsepower, when one of the at least two hydraulic pump circuits breaks down, to one or more operating hydraulic pump circuits;
- flowing a fluid from the hydraulically driven pump to a high-pressure fluid conduit;
- and
- injecting the fluid into a well via a fluid manifold fluidly coupled to the high-pressure fluid conduit.
