as the diverting agent is pumped into formation zone 14 the diverting agent will act to seal the fractures 24 and 24 a including any newly propagated fractures thereby reducing the permeability of the formation zone 14 and causing the fracturing fluid that follows the diverting fluid to flow to next most highly permeable formation zone such as formation zone 16 where the process is repeated until all of the formation zones 12 14 and 16 have been treated to increase the permeability of all of the formation zones 12 14 and 16 once all of the formation zones 12 14 and 16 have been treated the formation zones are not initially permeable due to the diverting agent that has been forced into each zone however with the presence of the catalyzing agent the diverting agent begins to break down in a few hours it is generally accepted that upon 80 of the diverting agent degrading the diverting agent is then able to flow out of the well once the diverting has degraded and begins to move out of the fractures and the formation zones the now increased permeability of the formation zones is restored fig2 and 4 depict a fluid loss control test fig2 depicts a slotted disk 100 having a 0 1 inch wide slot 102 through the slotted disk 100 fig3 depicts the fluid loss cell 110 the slotted disk 100 from fig2 is placed in to bottom.
