Embodiment Construction

[0030]The following description may use terms such as “horizontal”, “vertical”, “lateral”, “back and forth”, “up and down”, “upper”, “lower”, “inner”, “outer”, “forward”, “rear”, etc. These terms generally refer to the views and orientations as shown in the drawings and that are associated with a normal use of the invention. The terms are used for the reader's convenience only and shall not be limiting.

[0031]Referring initially to FIGS. 2, 3, and 4, the invented plant is in this illustrated embodiment arranged as a mobile unit 18 on a trailer 19 and enclosed by a housing 20. Doors in the housing provide access to the plant, and rear doors may allow the movable unit comprising fluid end 21 with its double-acting cylinders 22 to be moved out and down (see FIG. 3) when the plant is in operation. Pipes 21a are configured for connection to well piping (not shown).

[0032]Referring to FIG. 4, the mobile plant in the illustrated embodiment includes a gas turbine 26 connected via a duct 27a t...

Abstract

A plant for delivering a fluid in a conduit (10) comprises a prime mover (2), for example a gas turbine, which is configured to drive one or more fluid delivery systems (34a-c, 35a1-c1, 35a2-c2) for delivering a fluid in the conduit (10). A first sensor (16) is configured for sensing pressure variations in the pipe (10) and is connected to a first controller (7). The first controller (7) is configured to provide control signals to control valves (36a-c, 37a-c) for at least one fluid delivery system and to a control system (4, 3) for the prime mover (2). One or more hydraulic pumps (9a-c) are configured to operate the fluid delivery systems and are driven by the prime mover, whereby interaction between the hydraulic pumps and the prime mover is controlled based on sensed pressure in the pipe (10).

Description

RELATED APPLICATIONS[0001]This application is a continuation under 35 U.S.C. § 365 to International PCT Application No. PCT / NO2017 / 050307 filed Nov. 28, 2017, which claims priority to Norwegian Application No. 20161911 filed Nov. 30, 2016; the disclosure of each is incorporated herein in its entirety by reference.FIELD OF THE INVENTION[0002]Embodiments of the invention generally concern methods of controlling a prime mover which is configured to drive one or more fluid delivery systems for delivering a fluid in a conduit. This may be particularly useful in the extraction of shale oil and / or gas by means of pressure pumping equipment for well stimulation, commonly known as “hydraulic fracturing” or “fracking”, but is not limited to such operations.BACKGROUND OF THE INVENTION[0003]The majority of the equipment used for pressure pumping has been following the same principle for several decades: a trailer or truck mounted power pack (diesel-powered reciprocating engine, or a gas turbine...
