Slickline and e-line services play a critical role in well optimization, intervention, and data acquisition. Slickline tools focus on mechanical well interventions, while e-line tools enable data logging, perforation, and complex diagnostics. These are QWC core technologies used in modern oil and gas well servicing and optimization operations.
Slickline Jobs (Mechanical Interventions)
1. Setting and Retrieving Plugs – Bridge plugs, gauge hangers, and other downhole isolation tools.
2. Shifting Sleeves and Valves – Adjusting sliding sleeves to control reservoir flow.
3. Fishing Operations – Retrieving lost or stuck objects (e.g., wire, tools, tubing) from the wellbore.
4. Swabbing Operations – Removing fluids to initiate or improve well production.
5. Deploying and Retrieving Downhole Gauges – Installing and recovering pressure/temperature gauges.
6. Running Dump Bailer Operations – Placing sand, cement, or chemical treatments in precise downhole locations.
7. Paraffin and Scale Removal – Cleaning out accumulated debris and deposits.
8. Valve Actuation – Opening or closing downhole safety valves and subsurface control valves.
9. Tubing End Locator Runs – Identifying the end of the production tubing for future operations.
10. Wax and Hydrate Cutting – Breaking up and removing obstructions in tubing or flow paths.
11. Memory Gauge Runs – Deploying electronic pressure/temperature gauges for reservoir monitoring.
12. Cutting Wire and Tubing – Downhole wire and small-diameter pipe cutting.
13. Wellbore Cleaning – Running brushes or scrapers to clean tubulars.
14. Seating and Unseating Gas Lift Valves – Adjusting artificial lift systems.
15. Running Dummy Runs – Verifying well access and tool passage before critical runs.
16. Chemical Treatment Deployment – Spotting chemicals for corrosion control or stimulation.
E-Line (Electric Wireline) Jobs (Logging, Perforation, & Intervention)
1. Cased Hole Logging – Evaluating reservoir properties and well integrity (e.g., gamma ray, neutron, density logs).
2. Production Logging (PLT) – Measuring downhole fluid movement and diagnosing production issues.
3. Cement Bond Logging (CBL) – Assessing the quality of cement around casing.
4. Perforation Services – Running perforating guns to create communication between the wellbore and reservoir.
5. Pipe Recovery – Cutting or severing tubing/casing using explosives or mechanical tools.
6. Correlation Logging – Depth verification using gamma ray or casing collar locator (CCL) runs.
7. Caliper Logging – Measuring internal casing/tubing diameter for wear and deformation.
8. Downhole Camera Runs – Capturing visual footage of wellbore conditions.
9. Tractor-Conveyed Operations – Deploying tools in deviated or horizontal wells using e-line tractors.
10. Downhole Flow Monitoring – Using sensors to measure production flow rates and diagnose well issues.
11. Resistivity Logging – Measuring formation resistivity to determine hydrocarbon saturation.
12. Induction Logging – Evaluating conductivity in the formation for fluid identification.
13. Pulsed Neutron Logging – Determining oil/water saturation behind casing.
14. Hydraulic Fracturing Perforating and Logging – Pre- and post-frac well evaluation.
15. Leak Detection Logging – Identifying casing leaks or wellbore integrity issues.
16. Radioactive Tracer Logging – Monitoring fluid movement and fractures.
17. Fiber Optic Logging – Using distributed acoustic sensing (DAS) and temperature sensing.
18. Setting and Pulling Downhole Devices – Plugs, packers, and other well-control tools.
19. Explosive Services – Tubing punchers, jet cutters, and setting charges.
20. Well Abandonment Logging – Confirming integrity before plug and abandonment.
