5. Critical Design Features

  • Electrically Isolated Joints: Prevents current leakage for e-line tools

  • Smooth Bore Geometry: Minimizes wireline friction (Ra < 8 µin surface finish)

  • Magnetic Permeability < 1.05 μ (for logging tool accuracy)

  • API 5DP/ISO 11961 compliance with supplemental wireline standards

6. Field Applications

  • Cased Hole Logging:

    • Cement bond evaluation

    • Production profiling

  • Well Intervention:

    • Scale removal with chemical bailers

    • Stuck tool recovery

  • Completions:

    • Intelligent well component installation

    • Downhole sensor deployment

7. Maintenance Requirements

  • Post-job Inspection:

    • Eddy current testing for microcracks

    • Thread profile verification (API RP 7G-2)

  • Reconditioning:

    • Hardbanding repair on tool joints

    • Seal groove re-machining

  • Retirement Criteria:

    • 3% wall loss in critical sections

    • Cumulative fatigue damage >80%
