Wireline Origins & the Wire

1912: Conrad Schlumberger conceives the idea for electrical measurements

1927: First electrical downhole log in Pechelbronn, France1930’s: Introduction of ‘Round’ Slickline

Hand powered - wells were shallow

Measuring device hand held against the wire

Line Tension – felt by operators leather covered hand on the wire

Mechanically driven reels

Slickline Intervention and Diagnostics

Benefits

small footprint, mechanical integrity, logistical simplicity,

operational efficiency, cost effectiveness

Limitations

clarity of toolstring status

depth precision

downhole tool capability

over dependence on slickline operator’s experience level

. . . maintain the benefits, overcome the limitations

Digital Slickline Case Study – Non explosive setting

Accurate depth setting of 2.75” bridge plugs in 3.5” tubing

Six plugs set at depths ranging from 4,100 ft to 12,699 ft

Application: Digital Slickline LIVE Set

Six Plugs set without explosives using digital electro-hydraulic setting tool

Real time accurate setting depth achieved using real-time GR and CCL correlation

Plug setting QC provided through real time downhole tool status monitoring on surface

Wireline Efficiency Gaps – A Brief Summary

Torque/ Bird Caging/ Stranded armors

Gas Migration/ High Pressure Sealing

Excessive friction in deep wells

Limited running Speeds

Grease Injection & spillage

Large WHE and grease tubes

Limitations in Subsea Intervention

“Kinked “electric line

Bird-Nested electric line

Polymer encapsulated logging cable

Smooth jacketed outer profile

Compact Dual Packoff

New Generation Wireline

Improvements of Polymer Filled Wireline Cables

Creates a seasoned cable:• Faster running speed

• Time and risk reduction

Better sealing on high pressure wells:• Minimizes the use of grease for sealing

• Allows for faster running speeds

• Reduces risk of hydrocarbon release

Minimizes torque in the cable:• Allows for more runs between cable servicing

• Standard alloy cable requires servicing every 1-3 jobs

• Reduces incidents due to bird-caging / torque etc.

Eliminates gas migration:

• Between the core and inner armor wires

• Between inner and outer armor wire

Conventional Polymer Filled

Polymer Coated

Polymer Filled Wireline – Efficiency Gains

Torque/ Bird Caging/ Stranded armors

Gas Migration/ High Pressure Sealing

Excessive friction in deep wells

Limited running Speeds

Grease Injection & spillage

Large WHE and grease tubes

Limitations in Subsea Intervention

√ Torque Balanced Armor package

√ Sealable polymer filled cable

√ Friction reduced by 40%

√ Limited only by safe winch policy

√ Unique Well Control (no grease)

√ Compact “EziSeal” packoff

√ Enables deepwater intervention

Advanced Wireline Benefits

Faster RIH/POOH, Faster Rig Up

Encapsulated armors

No grease

Less friction

GRE (Glass-Reinforced-Epoxy) Lined tubing protection is applicable

Efficiency

Lower Risks

Reach the “Unreachable ” reservoir information

Environmentally Friendly
