Abstract
A method of conducting a pressure test on a piping and manifold system can include connecting a plurality of pumping units to a discharge manifold, connecting the wellhead of a well to the discharge manifold via a wellhead flowline, isolating the wellhead from fluid flow into the well to form a closed test system, and operating at least one and less than all of the plurality of pumping units to pressurize the closed test system to a predetermined pressure.
Claims21
A method of conducting a pressure test on a piping and manifold system configured to provide fluid flow from a plurality of pumping units into a well via a wellhead, comprising:
- connecting the plurality of pumping units to a discharge manifold, wherein a fluid outlet on each of the plurality of pumping units is in fluid communication with the discharge manifold via a discharge flowline;
- connecting the wellhead of a well to the discharge manifold via a wellhead flowline;
- isolating the wellhead from fluid flow into the well to form a closed test system;
- and
- operating at least one and less than all of the plurality of pumping units to pressurize the closed test system to a predetermined pressure, wherein fluid flows from the fluid outlet on each operating pumping unit through the discharge manifold to the fluid outlet on one or more non-operating pumping units.
A method of conducting a pressure test, comprising:
- isolating a pumping and piping system coupled to a wellhead of a well to form an isolated system by closing a valve to prevent fluid flow through the wellhead and into the well, wherein the pumping and piping system comprises a plurality of pumping units, each of the plurality of pumping units is in fluid communication with a discharge manifold via a discharge flowline, and the discharge manifold is coupled to the wellhead via a wellhead flowline;
- and
- pressuring the isolated system to a predetermined pressure with a fluid by operating less than all of the plurality of pumping units, wherein fluid flows from the operating pumping units through the discharge manifold to one or more non-operating pumping units,
- wherein each discharge flowline comprises a velocity fuse located between the discharge manifold and each of the plurality of pumping units.
An isolated pressurized test system, comprising:
- an isolated piping and manifold system coupled via a wellhead flow line to a wellhead of a well and having a closed valve to prevent fluid flow from the wellhead flowline through the wellhead and into the well,
- wherein the piping and manifold system comprises respective fluid outlets of a plurality of pumping units, and each of the respective fluid outlets is in fluid communication via a discharge flowline with a discharge manifold coupled via the wellhead flowline to the wellhead, and
- wherein the isolated pressurized test system is pressured to a predetermined pressure with a fluid by operation of less than all of the plurality of pumping units, wherein during pressurization fluid flows from one or more operating pumping units through the discharge manifold past a velocity fuse to one or more non-operating pumping units.
