Phase-shift resistivity

{
  "id": "MLC-T-OAG-002774",
  "term": "Phase-shift resistivity",
  "field": "Oil and gas",
  "definition": "A resistivity measurement derived from the phase shift of an electromagnetic wave propagating through the formation. This technique is employed by high-frequency induction logging tools, where the phase difference between transmitted and received signals is converted into a resistivity value. It is less affected by borehole conductivity than attenuation resistivity at higher frequencies.",
