Definition and Properties of a Slick line
 Small diameter wire with sufficient strength to accomplish the
operation without breaking – why small?
 Minimize the load of its own weight
 Minimizing the cross-sectional area reduces the effect of wellhead
pressure
 Enables the use of smaller diameter spools, reels and sheaves
without overstressing the material when bending

Schlumberger

Definition and Properties of a Slick line
When selecting Slickline, several factors should be considered
 Minimum breaking strain
 Resistance to corrosion
 Effects of bending
 Environmental conditions, desert dust, seawater, temperature
 Well Pressure
 Effecting the magnitude of force on the line diameter
 Influencing the effects of H2S

Slick line - testing
 Testing of Slicklines
 Before each operation, during the operation, when finished
 Three methods in use

 Other indicators
 Coil of the wire
 Marking, pittingof the line

Schlumberger

Slick line – bending cycles
 Bending stresses are created
whenever wire deviates fromthe a
straight line condition
 This in conjunction with sheave
size is the most common reason
for line failure
 When hand ‘jarring’ the cycling of
the sheave causes the material to
crystallize
 14bending cycles to run in and out
of the hole
