Claim Text:
1. A method of shearing an invert well fluid and flowing a well fluid into a well, comprising: forming a mixture comprising oil and water; pumping the mixture into an input chamber at a high pressure; dividing the mixture into a plurality of flow segments; reducing a pressure of the plurality of flow segments by flowing the plurality of flow segments through a plurality of nozzles to reduce the size of and elongate the water droplets, wherein the nozzles comprise convergent-divergent nozzles; discharging separate streams of the plurality of flow segments from the plurality of nozzles into a low-pressure stabilization chamber; intersecting the separate streams in the low-pressure stabilization chamber to form an emulsified invert well fluid; and flowing the emulsified invert well fluid from the low-pressure stabilization chamber through a low pressure fluid outlet into the well.
