  "term": "Propagation resistivity measurement",
  "field": "Oil and gas",
  "definition": "A technique used in logging-while-drilling (LWD) tools to determine formation resistivity by measuring the properties of an electromagnetic wave traveling through the formation. The tool measures the phase shift and attenuation of a high-frequency wave between a transmitter and two receivers. These measurements are then converted into resistivity values that are less affected by the borehole environment than laterolog or induction measurements made on wireline.",
