The disclosure presents systems and methods for hot swapping pumps at a wellsite while minimizing the impact to the pumping operations. As one pump is swapped out, such as for maintenance, the remaining pumps in the set of pumps at the wellsite can continue pumping operations. In some aspects, the pumps can be arranged around a central open area where the manifold pipes are located on the outside perimeter. This arrangement allows for a pump moving apparatus to remove and locate pumps at various positions around the perimeter while minimizing movement and minimizing the time the pump moving apparatus spends off of matting. The pump moving apparatus can be shielded with a protective barrier to protect the equipment or user from discharges from other pumps that are under high pressure.

Continuous pumping operations using central pump area

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.

Wellbore services system with anytime access for pump maintenance

Regulating downhole fluid flow through a plurality of valves to treat wellbore sections while also allowing for production to continue. If it is determined that fluid flow through a valve of a plurality of valves is below a threshold, maintaining fluid flow through the below threshold valve may be maintained while restricting fluid flow through other valves of the plurality. This restriction fluidly isolates a section of a well from other sections of the well. Once isolated, a treatment substance may be injected through the below threshold valve into the isolated section of well. Afterwards, the closed valves may be reopened while restricting fluid flow through the treated section valve for a threshold period of time. the treated section valve may then be reopened after the threshold period of time.

The disclosure presents systems and methods for hot swapping pumps at a wellsite while minimizing the impact to the pumping operations. As one pump is swapped out, such as for maintenance, the remaining pumps in the set of pumps at the wellsite can continue pumping operations. In some aspects, the swapping of pumps can be performed by a user using a protection barrier to isolate the pump location where the pumps will be swapped. In some aspects, one or more of the steps to swap pumps can be performed through automation thereby minimizing danger to a user. In some aspects, the pump being located at the pump system can be primed and pressure tested prior to be located to improve the time to enable the pump for pumping operations.

A pressure switch system provides a safety mechanism for equipment at a well site environment to prevent the opening or release of certain components when an unsafe condition exists. A pressure switch assembly of the system includes a diaphragm that transitions to an extended position as pressure of a pressurized fluid is flowed through a fluid pathway of the assembly. The diaphragm couples to a pin that transitions along with a dart based on the pressure at the diaphragm. When pressure reaches or exceeds a threshold, the dart is transitioned to a location proximate to a sensor. The sensor triggers actuation of a switch to prevent release or opening of a remote connector of a hydraulics unit until the pressure is at or falls below the threshold. The threshold is set to a pressure based on the unsafe condition.
