Profile Liner Technology
for isolation of complicated zones
while drilling
Our factory PERECRYVATEL LLC
Profile Liner Technology
Applicable:
 For isolation of complicated zones with total loss while drilling
 For isolation of productive layers from blocking it by drilling mud and cement
 For casing repairing while drilling
Application area:
 Vertical wells
 Deviated wells
 Horizontal wells
Technology for well design simplification
Standard
With PL application
• Profile liner set in series when meet
the loss zones
• Isolate the layers without diameter
loss
• Make the well design more simple

Profile pipe before and after expanding
After expanding 1 m of profiled
pipe can withstand to 150 Klbs
(70 t) of axial load
Underreamers
The well should be reamed by underreamer before PL running
Roller Reamers
Applicable for reaming of cylindrical part of PL and for
calibration of inside parts of PL after PL setting in a well

ECONOMIC EFFICIENCY
1. Time reduce for well drilling
2. Cost reduce for casing using
3. Cost reduce for drilling mud services
4. Cost reduce for transportation
5. Additional oil production due to the period of well drilling reduced
TECHNOLOGICAL EFFICIENCY
1. Solve the problem with total loss while drilling
2. Time reduce for well drilling
3. Isolate the layers without loss in diameter
4. Applicable without cementing
5. Intermediate casing excluded
6. Simplification of well design
7. Profile liner set in series when meet the loss zones
8. Reduced energy and materials
