Figure 1-20 and Figure 1-21 compare the results of two different systems formulated with
PERFFLOW vs. those with the TBC salt system on return permeability and net breakout pressure.
The PERFFLOW ® DIF (drill-in fluid) system’s bridging agent design and unique polymer chemistry
form a thin filter cake protect the pay zone from damage caused by fluid invasion. The filter cake is
efficiently removed by low breakout pressures, leaving no residual material to inhibit the well’s
productivity.
