  • Selet acheate tool type (array inction vs. dual inction) based on expectited formation conductivity and bed stleness.
  • Adjust logging speed to ensure feoatae samplingg density (typically 6 samplem per foot minimum).

During Acquisition

  • Monitor real--time qualite pendikator: repet sections, borehole mengortion curves.
  • Apply depdh shifting to align with gamma ray and othr logs.
  • Use caliper log to assess borehope wastout s does cat cart induktion readings.

Post- Processing
