Abstract: A secondary barrier is used adjacent a pump of a pumping unit that is in fluid communication with a wellbore services manifold system having a ballistic barrier. The secondary barrier includes a first portion configured to be disposed in proximity to a fluid end of the pump and configured to be disposed between the fluid end of the pump and a power end of an adjacent pumping unit pump, and a second portion configured to face the ballistic barrier and the wellbore services manifold system.

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.

Abstract: Disclosed embodiments include systems and methods for providing maintenance to a pump of a pumping unit in situ within a red zone of a pressurized wellbore services system. Ballistic barriers may be disposed between the pumping unit and the pressurized wellbore services manifold, and the pump may be remotely isolated from fluid communication with the wellbore services manifold and depressurized. Additionally, a secondary barrier, for example on a shielded work platform, may further protect workers, allowing for safe and efficient maintenance of the pump.

Abstract: A system and method for controlling a pumps configured to pump fluid from a fluid supply to a frac iron configuration. A pressure schedule is defined, the pressure schedule including a pumps assigned to sets of pumps, wherein each set of pumps is associated with a pressure level and wherein each set of pumps except a first set of pumps is a subset of a previous set of pumps. The first set of pumps is enabled to pump fluid continuously until the fluid in the manifold has reached a predetermined pressure level. A processor then automatically disables the electric pumps that are not in the next set of electric pumps, while allowing the next set of pumps to continue to pump fluid until the fluid in the manifold has reached the next pressure level. This continues until the manifold is at the desired pressure.
