As reported in the biography, quartz is the most sensitive mineral to the action of the water-jet, showing a good proportionality between the volume of the crater produced by the erosion and the pressure of the flow [39]. On quartz crystal, the water-jet mainly produces irregular cavities irrespective to the mineral form.

We jet the block on 4 sides and remove the block with plugs and feathers on the backside. The Water Jet uses approx 7.5 l/m (2 gpm) running at310,000 kPa (45,000 psi) to erode the crystals @ 1sm/h (10sf/h).The 0.533mm (.021") nozzle oscillates back and forth to achieve an approx 5cm (2") channel. Using the Jet, we do not lose corners or ...

The water jet drilling technology has shown significant effects in improving ROP. However, previous studies believed that water jets play a role in rock cleaning and assisting rock breaking (Lu et al., 2005; Li et al., 2020). Contrarily, we believe that water jets can release the stress at the well bottom, thereby enhancing the drillability of ...

A water jet cutter, also known as a waterjet, is a tool capable of slicing into metal or other materials (such as granite) using a jet of water (pure waterjet) at high velocity and pressure, or a mixture of water and an abrasive substance (abrasivejet).The process is essentially the same as water erosion found in nature but greatly accelerated and concentrated.
