Presentation Transcript

  1. Lecture items • Resistivity Logs * Definition. * Types * Units & Presentation. * Theories of measurement. * Factors affecting on log readings. * Applications.

  2. Resistivity Logs - Conventional resistivity logs. - Focused resistivity Logs. - Microspherically focused logs. - Induction logs.

  3. Resistivity logs “Definition” Such logs measure and record either resistivity or conductivity of the drilled sequence versus depth. Units & Presentations Units of measurements are Ohm.m or m.mhos/m Presentations: Tracks 2 &or 3 on logarithmic scale

  4. Conventional resistivity logs

  5. Normal and Lateral R. L.

  6. Short & Long Normal and Lateral RL.

  7. Theory offocusing system

  8. Spherically focused logsLL7, LL3 and SFL

  9. Dual Latero- logsLLS & LLD

  10. LLS & LLD logs

  11. Hydrocarbon effects on resistivity logs
