Abstract
A method for minimizing over pressurization during a pressure test of a fluid distribution system comprises a plurality of pumping units in fluid communication with a wellhead via a manifold. The method comprises pressurizing the fluid distribution system with a fluid using an initial number of pumping units to an initial predetermined pressure, and further pressurizing the fluid distribution system with the fluid using a final number of pumping units to a final predetermined pressure. The final number of pumping units is less than the initial number of pumping units.
Claims21
A method for minimizing over pressurization during a pressure test of a fluid distribution system comprising a plurality of pumping units in fluid communication with a wellhead via a manifold, the method comprising:
- pressurizing the fluid distribution system with a fluid using an initial number of pumping units to an initial predetermined pressure, and
- further pressurizing the fluid distribution system with the fluid using a final number of pumping units to a final predetermined pressure,
- wherein the final predetermined pressure is greater than the initial predetermined pressure,
- wherein the final number of pumping units is less than the initial number of pumping units, and
- wherein the final number of pumping units is operated continuously from pressuring with the initial number of pumping units to the initial predetermined pressure until the final predetermined pressure is obtained.
13-14. (canceled)
A method of conducting a pressure test, comprising:
- isolating a pumping and piping system coupled to a wellhead to form a closed system by closing a valve upstream from the wellhead, wherein the pumping and piping system comprises a plurality of pumping units in fluid communication with the wellhead via piping and a manifold;
- pressuring the closed system with a fluid using an initial number of pumping units to an initial predetermined pressure;
- and
- further pressurizing the closed system with the fluid using a final number of pumping units to a final predetermined pressure,
- wherein the final predetermined pressure is greater than the initial predetermined pressure,
- wherein the final number of pumping units is less than the initial number of pumping units, and
- wherein the final number of pumping units is operated continuously from pressuring with the initial number of pumping units to the initial predetermined pressure until the final predetermined pressure is obtained.
A method of pressure testing a manifold and piping coupled to a wellhead and isolated from fluid flow through the wellhead, comprising:
- starting pumping of a fluid by first number of pumping units in fluid communication with the manifold and piping to pressurize the manifold and piping to a first predetermined pressure;
- upon reaching the first predetermined pressure, halting pumping of fluid by one or more of the first number of pumping unit;
- continuing pumping of fluid with a second number of pumping units that is less than the first number of pumping units to pressurize the manifold and piping to a second predetermined pressure;
- and
- upon reaching the second predetermined pressure, halting pumping of fluid by the second number of pumping units,
- wherein at least one pumping unit of the second number of pumping units is different from the pumping units of the first number of pumping units, and the at least one pumping unit is different by comprising a clutch or a different power source.
