Abstract: A syringe assembly for a hydraulic fracturing system includes a syringe having a material chamber, a base fluid chamber, and a piston. The material chamber is configured to be fluidly connected to a fluid conduit. The piston retracts to draw material into the material chamber. The piston extends to push the material into the fluid conduit. The syringe assembly includes a diverter fluidly connected to the base fluid chamber and moveable between first and second positions. The first position of the diverter fluidly connects the base fluid chamber to a base fluid reservoir of the hydraulic fracturing system and fluidly disconnects the base fluid chamber from an outlet of a frac pump of the hydraulic fracturing system. The second position of the diverter fluidly connects the base fluid chamber to the outlet of the frac pump and fluidly disconnects the base fluid chamber from the base fluid reservoir.

Abstract: The invention relates to a tool and associated method for making closed operation in subsea wells possible, without the use of cable or coiled tubing up to the rig or ship. The object of this solution is to move such operations to lighter and more cost efficient vessels or ships which are not necessarily required to handle hydrocarbons up to the deck of the vessel. The basis of maintaining two independent well barrier envelopes is met even if the tool and the method for operation does not require cutting functions for isolating the well from the environment. The tool comprises a hoist arrangement, a seal element and connection points. The localization and arrangement of these are essential for the invention. The invention also adapts for use of traditional workover systems as alternative, independent operation, if the new technique should not complete the operation as planned.
